LeMond Carbon obtains independent verification of its carbon fiber rapid oxidation technology

LeMond Carbon announced the results of an independent technical audit conducted by Bureau Veritas (BV) of its carbon fiber manufacturing process.

The audit was conducted on a pilot line at Deakin University’s Carbon Nexus facility in Geelong, Australia. The total oxidation time and material properties verified by BV support LeMond’s claims to lower costs and significantly increased output versus traditional carbon fiber technology.

From Bureau Veritas audit of LeMond’s carbon fiber manufacturing process.


Bureau Veritas, founded in 1828, is a world leader in laboratory testing, inspection, and certification services. Widely regarded as a trusted brand synonymous with quality, BV is highly experienced at auditing innovative technologies and manufacturing processes.

For the audit of LeMond’s technology, BV measured total oxidation times of sub-15 and sub-20 minutes over two separate production campaigns of 24K standard modulus (SM) carbon fiber, achieving fiber tow properties in excess of 270 GPa tensile modulus and 3,500 MPa tensile strength.

The BV audit was conducted on Carbon Nexus’s 100 metric ton (nameplate) pilot line which is currently producing samples for trials with LeMond’s target customers in several SM industrial markets.

In addition to accurately measuring oxidation times and assuring process traceability, BV oversaw the fiber sampling, packaging and shipping of audit samples for extensive testing at the BV laboratories in Pessac, France. Composite tow tests of the LeMond fiber were completed according to ASTM D 4018-17 standards.

LeMond and Deakin University are teamed to commercialize this innovative technology which enables reductions of 75% and 70% in capex and energy consumption per kilo of output respectively. The rapid oxidation process enables LeMond to produce carbon fiber with the lowest embodied energy of any standard PAN-based carbon fiber available today.

This is a significant milestone for our company. Having our technology independently verified by BV validates the revolutionary nature of our technology. My team and I are excited to bring our high-performance low-cost carbon fiber to the global market, and look forward to expanding into new markets where the current high cost of carbon fiber has been a significant barrier to adoption.

—Greg LeMond, founder and chairman of the board of LeMond Carbon

Having proven the capability to successfully produce a competitive standard modulus carbon fiber, LeMond has launched a new capital raise to develop a 5,400-metric ton (nameplate) production facility in Oak Ridge, Tennessee. To date, parent LeMond Companies LLC has raised approximately US$18.6 million of seed capital from individual and institutional investors, including Deakin University.

Founded in 2016, LeMond Carbon Inc, headquartered in Oak Ridge, Tennessee, is commercializing carbon fiber manufacturing technology under a global 20-year license from Deakin University. Upon expected commencement of operations in 2021, LeMond Carbon intends to produce and to sell carbon fiber composite products to the wind, aerospace, oil and gas and auto industries where there is significant interest in our technology and strong adoption potential for lower-cost carbon fiber products.

Cheaper carbon fibre - sounds good to me,
Especially for aerospace.

As a bicycle enthusiast I took note of Lemond buying the technology back in 2016 and was wondering recently what had become of it. It is interesting to see how long it takes to move from the lab to production even in the modern fast paced world of today. If even a small proportion of the technological advances we read about here come to fruition, we're in for an avalanche of change in the coming decade.

I'd imagine reducing the weight by only a few hundred kg is equivalent to a major advance in battery energy density.

CF slows production regardless of cost. With the same unit cost but 30-50% faster, maybe this would be the real breakthrough? Also the news that BMW are writing-off i-cars with cracked chassis after impacts is alarming. These cars were supposed to be repairable. Lifetimes of CF frames should decades, not weeks. Maybe that is why the Porsche Taycan is heavier than the heaviest F150?
