以玉米淀粉和聚乳酸(PLA)为原料,甘油为增塑剂,通过熔融挤出法制备玻璃纤维增强淀粉/PLA复合材料。研究了玻璃纤维用量对复合材料断面形貌、力学性能、耐水性能和熔融性能的影响。结果表明,随着玻璃纤维用量增多,纤维与基体间的机械咬合作用使复合材料断裂面变得粗糙;纤维用量超过4%后,纤维之间产生相互缠结,对复合材料基体的增强效果减弱,使得断裂面的粗糙度下降。受玻璃纤维对基体增强效果的影响,随着纤维用量增多,复合材料的拉伸强度、弯曲强度和断裂伸长率都逐渐增大,吸水率逐渐降低,玻璃纤维用量为4%达到临界值。复合材料的储能模量随着玻璃纤维用量增多而增大,而熔融指数和复数粘度却随着...

Glass fiber reinforced starch/polylactic acid (PLA) composites were prepared by melt extrusion with corn starch and PLA as raw materials and glycerol as plasticizer. The effect of glass fiber content on the fracture morphology, mechanical properties, water resistance and melting properties of composites were studied. The results show that, with the increasing of glass fiber content, mechanical interlocking between fiber and the matrix of composites was result in the roughness of fracture surface. When fiber content was more than 4%, the entangl...
