摘　　要：以桦木锯屑和聚丙烯为原料,马来酸酐(MAPP)为偶联剂,采用SJSH30/SJ45双阶单双螺杆挤出机组制作木材纤维/聚丙烯复合材料。试验结果表明,随着桦木锯屑加入量的增加,复合材料强度呈下降趋势,当偶联剂的添加量为5%时,除桦木与聚丙烯塑料比例为30∶70复合材料的弹性模量有下降外,其余材料均表现出力学强度和弹性模量的显著增强;当偶联剂的添加量进一步增大到8%时,复合材料弹性模量的增加趋缓,因此,确定偶联剂的添加量为5%。Take birch sawdust and PP as raw material. MAPP as coupling agent. Use SJSH30/SJ45 two -stage single and double screw extrusion machine, it produced wood fiber/PP composite . The result showed that with the increasing of addition amount of birch sawdust, the strength showed that the decreasing tendency when the addition content of coupling agent was 5%, except the MOE of the composite in which the percent of birch and PP was 30：70 reduced, the mechanical strength and MOE of other composite all obviously increased. When the addition of coupling agent increased to 8% , the increasing of MOE became slowly. So the addition of coupling agent was 5 %.
