Abstract
This article investigated the influence of thermoplastic elastomer like acrylonitrile–butadiene–styrene (ABS) high rubber powder (HRP), and ethylene methylacrylate (EMA) on the mechanical performances, flow ability, and morphology of glass fiber‐reinforced polycarbonate (PC)/ABS blends. Blending was carried out through a twin‐screw extruder, and all testing specimens were shaped by an injection molding machine. Experimental results showed that the toughening effect of EMA was more obvious than HRP due to fracture mechanism like crazing, shear yielding occurred in corporation with EMA. About 15 wt% glass‐fiber (GF) reinforcement and 6 wt% EMA toughening can get a balanced behavior among strength, stiffness, and toughness for superior performance of the polymer. POLYM. ENG.
