Crashworthiness of recycled carbon fiber composites

The crashworthiness of discontinuous recycled carbon fiber composites was studied. Sinusoidal crush specimens were manufactured of acrylonitrile butadiene styrene, polyphenylene sulfide, and a common structural epoxy reinforced with recycled carbon fibers. Samples were tested at a range of strain rates and temperatures representative of automotive conditions. Crush debris size was quantified using sieving to correlate with energy absorption. The...
