利用甘蔗渣纤维作为增强剂，回收的聚丙烯塑料作为基体，并添加MAPP为偶联剂，通过熔融混合、注射成型法制成蔗渣纤维/PP 复合材料，研究蔗渣纤维和偶联剂对复合材料静态及动态力学性能的影响。结果表明：与PP相比，添加了蔗渣纤维和MAPP后，除抗拉强度外，复合材料的静态力学强度有所提高；复合材料的储能模量和损耗模量增加，而损耗因子降低；蔗渣纤维/PP复合材料的玻璃化转变温度Tg为61.8℃。

Bagasse fiber reinforced polypropylene composites were prepared by melt compounding and injection molding with bagasse fiber as the reinforcement, recycled polypropylene as the matrix material and MAPP as the coupling agent. The objective of this experiment was to study the influence of bagasse fiber and coupling agent on the static and dynamic mechanical properties of the composites. The results showed that with the addition of bagasse fibers and MAPP, the static mechanical properties of composites improved compared to PP. The storage modulus and the loss modulus increased with the addition of bagasse fiber and the loss factor decreased. The glass transition temperatures Tg of bagasse fibers/PP composites were at 61.8℃.
