Abstract


Originally developed for high-tech applications, carbon/epoxy composites
have been increasingly used in leisure and sports industries, for several
years. Nevertheless, the carbon reinforcement is an expensive constituent,
and it has been recently shown that it is also the most environmentally
impacting in a composite part manufacturing. In this way, recycling these
materials (even restricted to the reinforcement recovery) could lead to
reduce economic and environmental inadequacies, while satisfying
legislative requirements for their end-of-life.
This article is the basis for a life cycle analysis that assesses benefits and
environmental challenges of this recycling loop. The recovery of the carbon
reinforcement (based on the solvolysis of the matrix by water under
supercritical conditions) offers an average gain of 70% for all ecoindicators.
