High performance polyphenylene sulfide biocomposites with lightweight and sustainable hybrid fillers: biocarbon and recycled carbon fibers

Abstract

Sustainable hybrid fillers including biocarbon (BioC) and recycled carbon fibers (rCF) are used to reinforce the polyphenylene sulfide (PPS). The PPS biocomposites were compared with the conventional talc filled counterparts. The PPS/BioC/rCF biocomposites have comparable specific mechanical properties and thermal stability to the PPS/talc/rCF composites. However, the former has higher content of sustainable fillers, which provides better energy saving and emission reduction properties. The biocomposites filled with BioC/rCF showed a similar degradation process as talc/rCF counterparts during the heat aging process. This study can help open high-end application options (e.g. Electric Vehicle (EV) parts) of PPS composites reinforced by sustainable carbon fillers.
