To investigate the effect of morphology of multiphase polymer on the mechanical properties, Experiments are carried on Polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS) and PC/ABS blends. The yield stress, Possions ratio and tensile strength follow the law of mixture. On the other hand, the maximum value of fracture resistance is obatained for PC/ABS of weight ratios 80/20. For this PC/ABS, ABS particels are distributed in PC matrix. It was also shown that the fracture strain and the fracture plastic strain energy density decrease for PC and PC/ABS blends, but increases for ABS, with the increase of stress triaxiality. It can be concluded that tensile stress triaxiality makes PC brittle, but results in the toughening of ABS and PC/ABS blends, which is significantly different from the conventional metallic materials. It is also shown that rubber content has important effect on the deformation, fracture and toughening of PC/ABS blends.

为了研究多相聚合物的形态结构对力学性能的影响，对聚碳酸酯（PC）、丙烯腈-丁二烯-苯乙烯（ABS）和PC/ABS共混物进行了实验研究。屈服应力、泊松比和抗拉强度遵循混合律。当PC/ABS质量比为80/20时，材料的断裂抗力最大。对于这种PC/ABS，ABS颗粒分布在PC基体中。随着应力三轴度的增大，PC和PC/ABS共混物的断裂应变和断裂塑性应变能密度减小，而ABS的断裂应变和断裂塑性应变能密度增大。结果表明，拉伸应力的三轴性使PC发生脆化，但使ABS和PC/ABS共混物发生增韧，这与传统的金属材料有很大不同。橡胶含量对PC/ABS共混物的变形、断裂和增韧有重要影响。
