POSTECH researchers develop new high-strength, lightweight steel
February 27, 2015
Researchers at Pohang University of Science and Technology (POSTECH) in South Korea have developed a new type of steel with improved tensile strength and lightness. In their approach, they effectively utilized a brittle intermetallic compound (B2) that metallurgists usually try to suppress by modifying B2 morphology and dispersion in the steel matrix.
The specific tensile strength and ductility of the developed steels improve on those of the lightest and strongest metallic materials known, titanium alloys, the researchers said. The results, reported in a paper in the journal Nature, demonstrate how intermetallic compounds can be harnessed in the alloy design of lightweight steels.
Magna unveiling lightweight plug-in hybrid sportscar at Geneva show
Global automotive supplier Magna International Inc. will debut MILA Plus, an two-seat plug-in hybrid sports car, at the upcoming Geneva Motor Show. The lightweight (1,520 kg, 3,351 lb) concept vehicle, the latest member of the MILA family of concept vehicles (earlier post), offers an all-electric range of 75 km with reduced CO2 emissions of 32g/km.
System power output is 200 kW (272 hp), with 580 N·m of peak torque. The MILA Plus accelerates from 0-100 km/h in 4.9s; electric acceleration from 0-80 km/h takes 3.6s. The performance of the three-cylinder gasoline engine is enhanced by the addition of two electric motors—one between the internal combustion engine and transmission to drive the rear axle, and one on the electric front axle. This arrangement results in an electric all-wheel-drive system which transmits more torque to the road and results in improvement of vehicle maneuverability and dynamics.
Lux: carbon fiber to go mainstream in automobiles by 2025
February 22, 2015
Driven by a faster-than-expected pace of technology development, carbon-fiber reinforced plastics (CFRPs) will be poised to gain widespread adoption for automotive lightweighting by 2025, according to a new report from Lux Research, “Scaling Up Carbon Fiber: Roadmap to Automotive Adoption.”
Advances already underway in fiber, resin and composite part production will lead to a $6 billion market for automotive CFRPs in 2020, more than double Lux’s earlier projection. (Earlier post.) Even this figure is dwarfed by the full potential for CFRPs in automotive if they can become affordable enough for use in mainstream vehicles, Lux posits.

Researchers suggest hybrid graphene oxide/cellulose microfibers could supersede carbon fibers
January 16, 2015
Researchers from Nanjing Forestry University and the University of Maryland have designed high-performance microfibers by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers. The resulting well-aligned, strong microfibers have the potential to supersede carbon fibers due to their low cost, the team suggests in an open access paper published in the journal NPG Asia Materials.
The hybrid microfibers are much stronger than microfibers composed of 1D NFC or 2D GO alone. In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

January 14, 2015
|The new Ford GT on display in the Ford stand at NAIAS. Click to enlarge.|
In December, Ford President and CEO Mark Fields said Ford would focus on five key areas of innovation, one of them being performance. He said that more than 12 new performance vehicles would be introduced through 2020. (Earlier post.) At the North American International Auto Show (NAIAS) in Detroit this week, Ford delivered first proof of that focus with the reveal of the new Ford GT carbon-fiber supercar, as well as the new F-150 Raptor based on the new aluminum F-150 and the Shelby GT350R Mustang.
The stunning Ford GT—which received the EyesOn Design Award at NAIAS for best production vehicle—serves as a technology showcase for top EcoBoost engine performance, aerodynamics and lightweight carbon fiber construction. Beginning production late next year, the GT will the road in select global markets in honor of the 50th anniversary of Ford GT race cars placing 1-2-3 at the 1966 24 Hours of Le Mans. However, unlike today’s hybrid drive Le Mans racers, or the new Acura NSX hybrid supercar, also revealed at NAIAS (earlier post), the GT—nor any of the other Ford performance vehicles unveiled at NAIAS—makes no use of electric drive technology.
ASG life-cycle study finds aluminum Ford F-150 “Best Full-size Truck of 2015” from environmental and economic perspective
According to the latest annual life-cycle study from the Automotive Science Group (ASG), the all-new lightweight aluminum 2015 Ford F-150 leads the full-size light-duty truck competition in all environmental and economic performance areas; accordingly, ASG selected the F-150 as its Best Full-size Truck of 2015. According to ASG and the principles of ecological economics, environmental and economic considerations are equally important in determining a vehicle’s overall value. ASG’s proprietary vehicle rating platform—the Automotive Performance Index—analyzes both performance areas for a comprehensive vehicle assessment. ASG’s 2015 Study assessed 225 light-duty truck models.
Although the gasoline-fueled F-150 with 2.7L EcoBoost delivers 22 mpg (10.68 l/100 km) combined—1 mpg shy of RAM’s EcoDiesel—the F-150’s life-cycle environmental and economic performance “leaves RAM and others in the dust,” according to ASG. According to ASG, the 2015 F-150 holds the smallest life-cycle carbon footprint and lowest cost of ownership of any full-size truck in the North American market today. Ford has produced a lightweight aluminum-intensive truck that costs less and performs better than its conventional truck counterparts over the vehicle’s life-cycle, says Colby Self, managing director of ASG.
University of Tennessee to head $250M advanced composites manufacturing institute; Ford, Honda and Volkswagen members
January 09, 2015
The Department of Energy and a consortium of 122 companies, nonprofits, and universities led by the University of Tennessee-Knoxville will invest more than $250 million—$70 million in federal funds and more than $180 million in non-federal funds—to launch a Manufacturing Innovation Institute for Advanced Composites—the fifth institute to be awarded of the eight national institute competitions launched earlier (earlier post).
The new Institute for Advanced Composites Manufacturing Innovation (IACMI), announced today by President Obama, will focus on advanced fiber-reinforced polymer composites that combine strong fibers with tough plastics to yield materials that are lighter and stronger than steel. While advanced composites are used in selective industries such as aircraft, satellites and cars, these materials remain expensive, require large amounts of energy to manufacture and are difficult to recycle. IACMI is dedicated to overcoming these barriers by developing low-cost, high-production, energy-efficient manufacturing and recycling processes for composites applications.

New high-entropy alloy is as light as aluminum, stronger than titanium alloys
December 11, 2014
Researchers from North Carolina State University and Qatar University have developed a new high-entropy alloy that has a higher strength-to-weight ratio that they say is unmatched by any other metallic material. The researchers used mechanical alloying to combine lithium, magnesium, titanium, aluminum and scandium to make a low-density, nanocrystalline alloy (Al20Li20Mg10Sc20Ti30) with an estimated strength-to-weight ratio that is significantly higher than other nanocrystalline alloys and is comparable to ceramics. An open access paper on their work is published in the journal Materials Research Letters.
High-entropy alloys (HEAs) are a new class of multi-component alloy systems in which the design of the alloys is based not on adding to a single base element, but on choosing elements that will form solid solutions when mixed at near-equiatomic concentrations. (Earlier post.) HEAs

Industry report says steel can deliver weight savings to meet CAFE targets; aluminum growth in LDVs to peak around 2018
October 06, 2014
Steel can easily deliver the weight savings required to meet federally mandated fuel economy targets for most vehicles, according to a new 300-page analysis by the steel-industry information service World Steel Dynamics: “AutoBody Warfare: Aluminum Attack.” The report, based on WSD’s independent consultation with steel, aluminum and automotive experts, is formally being presented to steel executives today at the worldsteel Annual Conference in Moscow.
The report, say the authors, comes in the context of the “high-stakes contest” between the world’s leading steel and aluminum companies instigated by the rise in the US Government’s CAFE standards. Aluminum companies are in an “ebullient mood”, WSD says, due in part to the aluminum-bodied 2015 Ford F-150 (earlier post) and an Aluminum Association report, authored by the Ducker Worldwide consulting group, forecasting that by 2025 three-in-four pickup trucks will have an all-aluminum body. (Earlier post.)

Citroën will unveil its new C4 Cactus AIRFLOW 2L concept at the Paris Motor Show. With the C4 Cactus AIRFLOW 2L concept, Citroën is demonstrating fuel consumption of 2l/100 km (118 mpg US) through the use of optimized design with a 20% improvement in aerodynamics; lower rolling resistance (Tall&Narrow) tires; efforts to use lighter parts and thus reduce overall vehicle weight by 100 kg; and the implementation of Hybrid Air technology (earlier post), which cuts fuel consumption by 30%.
The C4 Cactus AIRFLOW 2L project was conducted as part of the “2l/100 km vehicle” program set up by the Plateforme de la Filière Automobile, an industry group. The objective was to deliver practical solutions to reduce the impact of vehicle running costs, on household expenditure and to reduce the eco-footprint of car travel.
MAHLE NanoNapier Steel piston ring helps reduce weight and improve quality
MAHLE has developed a piston ring with new technology that offers engine manufacturers improvements in weight, quality and overall value. MAHLE’s new “second” piston ring uses chrome-silicon steel to replace cast iron traditionally used for the second of three rings found on gasoline-powered spark-ignition engines. MAHLE’s thinner, lighter-weight steel-wire design for the second ring is based on the company’s own NanoNapier Steel (NNS) technology for which a patent is pending.
Conventionally, there are two types of piston rings: compression and oil control. A piston assembly includes one or more compression rings that generate a seal between the outer surface of the piston and the wall of the cylinder to prevent high-pressure combustion gases and air from escaping the combustion chamber. Today’s engines have three piston rings: two compression rings: top (or first) and second and the oil control ring. The second ring is known as a Napier ring.

|EOLAB. Click to enlarge.|
Renault has presented EOLAB, a new prototype which explores ways to deliver ultra-low fuel consumption. EOLAB delivers NEDC combined cycle fuel consumption of 1 liter/100 km (235 mpg US), equivalent to 22g of CO2/km. To achieve such low figures, the designers focused their efforts on three main areas: minimizing weight; leveraging aerodynamics with active systems; and using the “Z.E. Hybrid” plug-in hybrid system—the last offering all-electric trips of up to 60 km (37 miles) at speeds of up to 120 km/h (75 mph).
Conceived around a B-segment platform, the prototype incorporates around 100 new, realistic technological developments that are designed to be introduced gradually on upcoming Renault vehicles. EOLAB features materials such as magnesium and aluminium, which are extremely light and also much cheaper than titanium. Meanwhile, the notion of such a car being produced in large numbers within the next 10 years was dialed into the plan from the start.

Mercedes-Benz outlines synergies between F1 motorsport and production car engineering
July 10, 2014
Mercedes-Benz has outlined areas of actual synergies between its F1 motorsport activities with Mercedes AMG Petronas and Mercedes-Benz Cars. While there is definitely a technology transfer between race and road car engineering, said Paddy Lowe, Executive Director (Technical) at Mercedes AMG Petronas, “it’s a more subtle process than bolting bits from one car onto another.”
There are examples of direct transfer—such as the Nanoslide technology used to coat cylinder bore surfaces (earlier post)—and then there are examples of indirect transfer, such as F1 serving as a research laboratory for developing new solutions and showing the world what is possible, he noted.

LLNL/MIT team creates ultralight, ultrastiff metamaterials; possible applications for automotive and aerospace
June 20, 2014
Researchers at Lawrence Livermore National Laboratory and Massachusetts Institute of Technology (MIT) have developed materials with the same weight and density as aerogel (“frozen smoke”) but with 10,000 times more stiffness using additive micro-manufacturing processes. The research team’s findings are published in an article in the journal Science.
The micro-architected metamaterials maintain a nearly constant stiffness per unit mass density, even at ultralow density. This performance derives from a network of nearly isotropic microscale unit cells with high structural connectivity and nanoscale features, the structural members of which are designed to carry loads in tension or compression, the researchers said. Materials with these properties could someday be used to develop parts and components for aircraft, automobiles and space vehicles.
The technology behind Ford’s Lightweight Concept Vehicle; prospects for Mach-II with 50% mass reduction difficult
June 18, 2014
Earlier this month, Ford unveiled its Lightweight Concept vehicle, which uses advanced materials to explore future weight-reduction solutions that could improve performance and fuel efficiency while reducing CO2 emissions. The Ford Lightweight Concept reduces the weight of a 2013 Fusion to that of a Ford Fiesta, resulting in a nearly 25% weight reduction. (Earlier post.)
The Ford vehicle is based on the first phase (Mach-I) of work of the DOE-supported Multi-Material Lightweight Vehicles project (Award DE-EE0005574) by Vehma International (an engineering and prototype division within the Cosma International operating unit of Magna) and Ford. The $20.3-million project ($10 million from DOE, $10.3 million from Vehma/Ford) has two main objectives. First, to design and build the “Mach-I” prototype vehicle maintaining donor vehicle architectural space and using commercially available or demonstrated materials and processes while delivering a 22% reduction compared to the baseline vehicle. The result of this is reflected in the Ford concept.
New robotic friction stir welding method for mixed materials; potential application for battery integration
June 11, 2014
|New friction stir welding tool also functions as a temperature sensor for improved quality. Click to enlarge.|
Researchers at University West in Trollhättan have addressed two drawbacks to the robotic friction stir welding (FSW) joining process for mixed materials—path accuracy and temperature—with the development of a deflection model and integral temperature controller.
Car manufacturers are increasingly looking to a hybrid or mixed materials design, in which a combination of different materials such as steel and aluminium are joined, for weight reductions in their vehicles. With classic welding methods, joining of dissimilar materials has not been possible. With friction stir welding (FSW), on the other hand, high quality dissimilar joints can be obtained. (Earlier post.) The use of industrial robots also allows FSW of materials along complex joint lines.

By 2025, more than 75% of all new pickup trucks produced in North America will be aluminum-bodied, according to a survey of automakers conducted by global consulting and research firm Ducker Worldwide and commissioned by The Aluminum Association’s Aluminum Transportation Group (ATG). The study surveyed all major automakers and forecasts that Ford, General Motors and Fiat Chrysler will become the biggest users of aluminum sheet in the next decade.
It also forecasts that the number of vehicles with complete aluminum body structures will reach 18% of North American production, from less than 1% today. Vehicle segments revealed as emerging aluminum content leaders are pickup trucks, sport-utility vehicles (SUVs) and both mid-sized and full-size sedans.

Ford Motor Company unveiled its Lightweight Concept vehicle, which uses advanced materials to explore future weight-reduction solutions that could improve performance and fuel efficiency while reducing CO2 emissions. The Ford Lightweight Concept reduces the weight of a 2013 Fusion to that of a Ford Fiesta, resulting in a nearly 25% weight reduction.
The vehicle represents the latest phase of Ford’s research into developing sustainable technology solutions that are affordable for consumers and can be produced in large volumes across the product lineup. This research has also led to the significant weight reduction of up to 700 pounds (318 kg) in the all-new F-150 through the use of high-strength steel and aluminum. (Earlier post.)
Ford and Samsung outline R&D efforts for next-generation non-hybrid battery technology; dual-battery systems and lightweight Li-ion
In an event in San Francisco, Ford Motor Company and Samsung SDI, an affiliate of Samsung Group, outlined several collaborative research efforts on next-generation battery technology for non-hybrid vehicles. For the near term, they have been working on a dual-battery combining a lithium-ion battery with a 12-volt lead-acid battery that could enable regenerative braking technology in non-hybrid vehicles for greater fuel savings. Ford suggested the dual battery system might go into production soon.
Ford and Samsung SDI said they are also are researching a longer-term (e.g., about 10 years) ultra-lightweight lithium-ion battery that could one day supplant lead-acid batteries. The research advances lithium-ion battery technology currently available on Ford’s electrified vehicles.

Due to the high demand for carbon fiber in automotive production, SGL Automotive Carbon Fibers, a joint venture between the BMW Group and the SGL Group, will triple the capacity of the carbon fiber plant in Moses Lake, Washington. SGL and BMW made the announcement at the groundbreaking ceremony for the planned site expansion. The expansion will be funded by an investment of US$200 million, on top of the previously invested US$100 million.
The site expansion, scheduled to be completed by early 2015, will make the plant in Moses Lake the world’s largest carbon fiber plant. At present, the Moses Lake plant operates two production lines, exclusively for BMW i, with an annual output of approx. 3,000 tons of carbon fiber. The expansion of the site in Moses Lake will make it possible for the BMW Group to apply carbon fiber material also in other model series in the future, at competitive costs and in large quantities.

The GM China Advanced Technical Center (ATC) in Shanghai announced the operation of its magnesium alloy Vertical Squeeze Casting (VSC) machine—the first designed for developing next-generation magnesium castings. GM said that this achievement marks a breakthrough in its lightweight materials research.
Squeeze casting is a process in which molten metal is introduced to casting cavities with minimum turbulence and then solidifies under very high pressure (typically above 100 MPa) within closed dies. The absence of turbulent metal flow, aided by the high applied pressure, can suppress gas porosity, notes Ohio State University Professor Alan Luo in a 2013 review of magnesium casting technologies.

The 2015 Chevrolet Colorado uses engineering techniques and lightweight materials to create fuel-efficient pickup capability in a mass-efficient mid-size package. The 2015 Colorado 4x4 crew cab, which GM expects to be the most popular version of the new trucks, weighs 880 to 1,400 lbs (363 to 635 kg) less than a full-size truck. Chevrolet expects EPA fuel economy estimates for Colorado this summer.
This weight saving is a result of the slightly smaller overall dimensions of the Colorado, along with extensive use of lightweight materials, including high-strength steels and aluminum.
