Mechanical Properties of Recovered Carbon Fibers


The use of Fiber Reinforced Polymers (FRP) has grown significantly since their introduction. Increased interest in environmental issues could inhibit their growth unless a cost effective way to recycle FRP is developed. This test program investigates the feasibility of using pyrolysis to recover carbon fibers from FRP composite scrap. Several runs were done on a bench scale pyrolysis unit to optimize the processing parameters. A larger pyrolysis unit was used to recover enough carbon fibers to perform mechanical property tests. The recovered fibers and virgin fibers were formulated into a molding compound. Panels were press molded and samples were tested in tension. The testing proved that pyrolysis could be used to successfully recover carbon fibers from scrap FRP composites.
