| 摘 要： | 以木纤维、竹纤维和聚苯乙烯为主要原料,加入偶联剂、润滑剂、增塑剂等加工助剂,经挤出注塑制备聚苯乙烯/木纤维复合材料。研究了植物纤维种类和添加质量分数、偶联剂KH-550添加质量分数对PS木塑复合材料力学性能的影响。结果表明：木纤维和偶联剂的加入都使复合材料的力学性能呈先增大后减小的趋势。当木纤维添加质量分数为25%,偶联剂KH-550添加质量为木纤维添加质量的1.5%时,复合材料具有最大的拉伸强度、弯曲强度和断裂伸长率,分别为30.2MPa,86MPa和8.74%,缺口冲击强度随木纤维添加质量分数的增加而减小。木纤维和竹纤维填充的两种复合材料的拉伸强度、弯曲强度和冲击强度相差不大。

| Abstract: | Natural fiber, bamboo fiber and PS were used as raw materials to prepare the fiber reinforced composites with certain coupling agents, lubrication agents and plasticizer. The results show that: the mechanical performances of the composites increase with concentration of both fiber and coupling agent, with the optimum value of 25wt% natural fiber and 1.5wt% coupling agent KH550, where the tensile strength, bending strength and elongation rate at break reach 30.2MPa, 86MPa, 8.74% respectively, but the notched impact strength decreases; there exists little deviation on mechanical properties between natural wood fiber and bamboo fiber filled polymer composites. |
