Study on Toughening of Chinese Herb Residue Fiber/Recycled ABS Composites

Abstract

The Chinese herb residue (CHR) fiber obtained by blasting through a continuous steam explosion device, and recycled acrylonitrile-butadiene-styrene (ABS) were blended to prepare reABS/CHR fiber composites by a vane extruder. Three kinds of thermoplastic elastomers: POE, SEBS and TPU were used to toughen composites. The results of toughening effects, mechanical properties and thermal stability properties show that: there were significant effects of these agents on impact strength; the compatibility not only affects toughening result, but also other properties; the best toughening agent for reABS/CHR fiber composites is TPU.
