Abstract: With the use of carbon fiber reinforced plastics (CFRP) poised to significantly increase in the automotive, aerospace, and sporting goods industries, there is an urgent need to develop recycling pathways for composite scrap and end-of-life parts. This work was performed to compare two different pathways of recycling CFRP waste: mechanical versus chemical recycling. Cured epoxy-matrix CFRP was mechanically recycled via pulverization, and then this pulverized CFRP was used in a chemical recycling process to liberate fibers. These two feedstocks were compounded with Nylon 6,6 into two different thermoplastic short fiber composites to study their impacts as a filler/reinforcement. Each material was injection molded into test specimens for analysis of their thermal (melt and crystallization), physical (density), and mechanical properties (tensile). Values obtained from the recycled molding compounds are compared to literature values of commercially available virgin materials.
