Cadillac CT6 mixed-material body structure saves 90 kg over predominantly steel construction
March 15, 2015
Cadillac will use an advanced mixed-material approach for the lightweight body structure of the upcoming CT6 range-topping full-size sedan, which will debut 31 March at the New York International Auto Show. The structure is aluminum-intensive, but the new Cadillac also includes 13 different materials customized for each area of the car to advance driving dynamics, fuel economy and cabin quietness; the mixed material approach saved 90 kg (198 pounds) compared to a predominately steel construction.
Sixty-four percent of the CT6 body structure is aluminum, including all exterior body panels. Thirteen complex high-pressure die cast components make up the lower structure of the CT6 body, along with aluminum sheets and extrusions. The vehicle underbody uses steel close-out panels on the lower structure to create a bank vault-quiet cabin without the added weight of extensive sound-deadening material, often used to compensate for aluminum panels in the occupant compartment.
Making the Mirai fuel cell vehicle
February 24, 2015
In Japan, Toyota Motor held a production ceremony at the Motomachi Plant, which first began production in 1959, to mark the production of the Mirai fuel cell vehicle, which the company launched in November 2014, and began selling in Japan in December 2014. (Earlier post.)
Motomachi has been home to some of Toyota’s most notable models, including the Publica, Corona, Cresta, Soarer, Supra, RAV4, and the Lexus LFA supercar. The former “LFA Works”—where craftspeople hand-built each of the 500 series limited Lexus supercars—is now the home of the Mirai. Toyota released a set of 5 short videos giving an overview of Mirai production, which delivers an estimated 3 units per day.
New human-robot cooperation in Audi’s final assembly processes
February 16, 2015
At its main plant in Ingolstadt, Audi has for the first time deployed a robot that works “hand-in-hand” with humans—without a safety barrier and ideally adapted to the employees’ working cycles. It is the first human-robot cooperation at the Volkswagen Group to be applied in final assembly. The technology makes work easier for the assembly employees and makes ergonomic improvements, the company said.
Formerly, employees of the A4/A5/Q5 assembly lines at Ingolstadt had to bend over material boxes to take out the coolant expansion tanks. This might seem a simple task, but with frequent repetitions it can lead to back problems. Now, however, the task will be taken over by a specialized KUKA robot, known internally as “PART4you” (Produktions-Assistent reicht Teil). (Volkswagen AG is increasingly working with Germany-based robot manufacturer KUKA; in late 2012, the Group awarded KUKA a contract for 6,000 robots for various plants—KUKA’s largest single blanket order.)

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 KIT process could triple manufacturing speed of electrode foils for Li-ion batteries
October 23, 2014
|Intermittent coating with precise edges: The process developed by KIT allows for the coating of electrode foils at new record speed. (Photo: M. Schmitt/KIT) Click to enlarge.|
Scientists at the Karlsruhe Institute of Technology (KIT) have developed a new manufacturing process for the batch-wise coating of Li-ion battery electrode foils that they say can boost the conventional processing rate by about a factor of three to 100 meters per minute. The team headed by Professor Wilhelm Schabel and Dr. Philip Scharfer of the Thin Film Technology (TFT) group of the KIT Institute of Thermal Process Engineering developed a flexible slot die process that enables production of any pattern with high precision and at high speeds.
So far, a rate of about 25-35 meters per minute has been the industrial state-of-the-art. In its just-released “Roadmap for Battery Production”, the German Engineering Association (VDMA) is targeting reaching a coating speed of 70-100 meters per minute by 2030. (In a recent techno-economic analysis of Li-ion battery manufacturing, a CMU/MIT team used 10 meters per minute as the assumed coating processing rate. Earlier post.)
CMU/MIT study finds large-scale battery manufacturing will do little to reduce unit costs past a 200-300 MWh annual production level
October 22, 2014
A new techno-economic analysis by researchers at Carnegie Mellon University (CMU) and MIT has found that economies of scale for manufacturing current Li-ion batteries for light-duty EV applications (in this case, prismatic pouch NMC333-G batteries and packs) are reached quickly at around 200-300 MWh annual production. Increased volume beyond that does little to reduce unit costs, except potentially indirectly through factors such as experience, learning, and innovation, they determined.
“That’s comparable to the amount of batteries produced for the Nissan Leaf or the Chevy Volt last year,” said CMU’s Dr. Jeremy Michalek, the corresponding author of a paper on the research published in the Journal of Power Sources. “Past this point, higher volume alone won’t do much to cut cost. Battery cost is the single largest economic barrier for mainstream adoption of electric vehicles, and large factories alone aren’t likely to solve the battery cost problem.”

Pilot at BMW Munich plant evaluating use in vehicle assembly of custom orthotic devices produced by 3D printing
A pilot project in BMW’s Munich vehicle assembly plan is exploring the benefits of a new and innovative ergonomic tool—a flexible finger cot, which protects workers against excess strains on the thumb joints while carrying out certain assembly activities. The project is part of a dissertation in cooperation with the Department of Ergonomics at the Technical University of Munich.
Each of the flexible assembly aids is a unique piece, customized to the match the form and size of a worker’s hand. The BMW Group makes these orthotic devices in-house, using additive production procedures—i.e., “3D printing”.
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.
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.

May 27, 2014
|New two-wet monocoat paint process. Click to enlarge.|
Ford began production of the North American Transit at Kansas City Assembly Plant on 30 April, and vans will be available in US and Canada this summer. Transit vehicles built in Kansas City are the first to use a new two-wet monocoat paint process developed by Ford and its paint suppliers. The technology results in more durable paint, uses less energy and water, and reduces carbon dioxide and particulate emissions compared with conventional paint processes.
The new paint was subjected to testing simulating typical conditions the vehicle will see over 10 year—e.g., resistance to chipping and scratching, pollutants and sun exposure. Data from preliminary advanced weathering testing indicates that paint applied with the new two-wet technology will retain 90% of its gloss at four years in service compared to 1% gloss retention for paint applied using a conventional monocoat process.

|Magnesium alloy VSC machine. Click to enlarge.|
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.
