摘　　要：晶须是一种单晶纤维,具有很高的强度和弹性模量,作为树脂基复合材料的填充体具备填充度高、增强效果明显等优点。晶须树脂基复合材料可以制备出形状复杂的薄壁、高尺寸精度、表面光滑的零部件。采用平行双螺杆挤出机熔融共混后注射成型制备一系列晶须含量的镁盐晶须/ABS复合材料,结合力学性能测试和扫描电镜分析镁盐晶须对ABS的增强作用。实验结果表明:镁盐晶须的加入可以提高复合材料的力学性能,拉伸强度和拉伸模量都随着晶须含量的增加而增加,其中弹性模量的增强作用更为显著,但同时,晶须的加入限制了树脂基体的变形,断裂应变和冲击强度都有一定程度的降低。The M--HOS/ABS composites with varied content of whiskers were compounded by extru- der and molded by injection molding. Mechanical testing and scanning electron microscope （SEM） were performed to investigate the effects of addition of M--HOS whiskers on reinforcement of ABS resin. The results show that mechanical properties of the composites have improved. The tensile strength and tensile modulus increase as whisker content increases. The modulus reinforcement of whisker to composites is significant. However, breaking strain and impact strength decrease, to a degree, due to the strong restriction effect of M-HOS whiskers on the matrix deformation.
