Surface free energy study of virgin and recycled carbon fiber reinforced thermoplastic composites

This research paper reports the composite adhesion behavior of thermal treated recycled carbon fibers through contact angle and surface energy measurements and its results compared with virgin carbon fibers. Virgin and recycled carbon fiber composites in a hybrid Polypropylene/Polyamide12 (PP/PA12) matrix had its pure blend surface data measured from 50% up to 80% PA12 weight content compared with its selected 20%-80% PP/PA12 modified Maleic …
