Ramie fiber (RF) was used to reinforce the polypropylene (PP).The composites were prepared with a melting hybrid technology.Tests had been performed on PP and composites with different RF contents (10,20,and 30 wt%).The effects the RF loading were assessed on the basis of morphologies and mechanical properties.The results show that the tensile strength of composites decreases by the presence of RF.And the impact strength of the composites is improved by the unmodified RF.As the unmodified RF is used directly,combined with the low price,so,a facile and economic preparation pathway is given by using unmodified natural fiber to reinforce polymer and composites with good mechanical performance are obtained.

Dyneema复合材料层合板由体积比为83％的超高分子量聚乙烯纤维和17％的聚亚安脂基体构成.本文就由该Dyneema复合材料层合板切割而成的悬臂梁进行了实验和数值模拟分析.从实验结果可以看出短梁发生弹性变形以及纵向剪切主导的塑性破坏:长梁变形过程中发生微屈曲(microbuckling)并在固定端附近形成一个塑性铰(plastic hinge),该塑性铰由两个楔形扭折区(kind band)组成
近些年来,以高性能工程塑料为基体的热塑性复合材料由于其自身耐热性能的提高,外加其更高的耐冲击性和抗疲劳性,可回收再利用,工艺周期短,制造成本低,越来越受到研究者们的关注.本课题组开发的含有杂萘联苯结构的聚芳醚( PPAE)是一种既可溶解,又耐高温的高性能工程塑料.本实验用连续碳纤维(T700-12K)作为增强材料,杂萘联苯共聚芳醚砜(PPBES,Tg=260℃)为树脂基体,采用溶液浸渍和模压成型的
