– Recovery of High Quality Carbon Fibers from End-of-life Carbon Fiber Reinforced Plastics

 - 

Carbon Fiber Reinforced Plastics (CFRPs) recycling is very challenging and yet is in high demand, consequence of the increasing use of this material in the automobile and wind energy industries and the high cost of carbon fibers in the market. The existing solutions for CFRPs recycling today often impact on the quality of obtained recycled fibers, thus preventing their use in high-value applications. Aiming to mitigate some of the inconveniences of these processes, we developed a new technology that uses vaporsolvolysis at low temperature and low pressure to degrade the composite resin and recover high quality fibers. In this work, we present the preliminary study and process optimization that led to the final technology as well as the versatility tests proving that the chosen process is compatible with different thermoset and thermoplastic resins.
