摘　　要：利用常压介质阻挡放电等离子体对超高分子量聚乙烯和聚丙烯纤维进行表面改性,研究了处理前后聚乙烯纤维的力学性能的变化和纤维束与环氧树脂粘合性能的改善情况,以及等离子体处理对聚丙烯纤维吸湿改性的影响。结果表明,纤维束在断裂强度相对较低的情况下,纤维与树脂的层间剪切应力有比较大的提高,此外,等离子体处理后经观察发现,聚丙烯纤维的微观表面出现了明显的凹坑和裂纹,其吸湿性能得到了提高。Surface modification about ultrahigh molecular weight polyethylene fibers and polypropylene fibers is done by dielectric barrier discharge plasma in this paper. The changes of mechanical properties of fiber bundle before and after treatment and improvement situation about bonding performance between fiber bundle and epoxy resin are studied. This paper also discusses improvement situation about wetting property of polypropylene fibers. The experimental results show that interlamination shear strength between fibers and epoxy resin has higher improvement accompanying with lower descent of abruption stress. What is more, after treatment, microscopic surface of polypropylene fibers have ruts and cracks and its wetting property gains improvement.
