本文使用短茇麻纤维（RF）增强聚丙烯（PP）复合材料，通过双螺杆挤出和注射成型工艺制备。实验结果表明，复合材料的强度和模量随茇麻纤维含量增加而显著提高。当茇麻纤维含量达30 wt%时，拉伸强度和弯曲强度分别高达67和80 MPa。这是短天然纤维增强PP复合材料的最佳结果之一。形态学分析显示，高长径比纤维和良好的界面相容性是实现高性能的关键因素。

Short ramie fiber (RF) was used to reinforce the polypropylene (PP). The composites were prepared in a twin-screw extruder followed by injection molding. The experimental results showed that both the strength and the modulus of the composites increase considerably with increasing RF content. The tensile strength and flexural strength are as high as 67 and 80 MPa by the incorporation of ramie up to 30 wt %. To the best of our knowledge, this is one of the best results for short natural fiber-reinforced PP composites. Morphological analysis revealed that it is the high aspect ratio of the fiber and good interfacial compatibility that result in the high performance of the composites.
