摘要：
Low cycle fatigue crack propagation(FCP)behavior of two PC/ABS blends with a weight ra-tio of PC to ABS being 80/20 and 60/40,respectively,is investigated.Experiments are carried out by usingstandard compact tension(CT)specimens.The fracture surfaces are examined with a scanning electron mi-croscope(SEM).It is shown that the FCP resistance of PC/ABS blend with 20% ABS particles is higherthan that of PC/ABS blend with 40% ABS particles.It is found that proper ABS particle content can resultin the toughening of PC/ABS blends through particle cavitation and shear yielding in matrix.
