The Synergy Effects of Styrene-Maleic Anhydride Copolymer and Epoxy Resin on Interface Adhesion of ABS/Short Glass Fiber Composites

Abstract

The effects of styrene-maleic anhydride copolymer (SMA) and epoxy resin (ER) on the interfacial interaction of Acrylonitrile-butadiene-styrene terpolymer/Short glass fiber composites were investigated by means of scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), and mechanical properties. The experimental results demonstrate that SMA and ER could effectively improve interfacial interaction between the ABS and SGF. Based on SEM, good interfacial adhesion between ABS and SGF in ABS/SMA/ER/SGF and ABS/ER/SGF composites was observed. DMA results showed that SMA and ER decreased the glass transition temperature (Tg) and height of tanδ compared with ABS/SGF composites. The synergy effects of SMA and ER on the interface interaction was investigated. All results in this paper were consistent, and showed a good interaction between ABS and SGF, which was proven by the mechanical properties of the composites.
