| 摘 要： | 超高分子量聚乙烯(UHMW-PE)纤维经过低温氧等离子体处理后,与环氧树脂基体的界面粘结性能明显改善.本文通过单纤维拔出实验、XPS、SEM、接触角测算等研究了表面改性的作用机理.对影响界面粘结的作用力进行了定量分析,揭示了表面刻蚀坑引起的界面机械铰链力,以及由多种含氧极性基团引起的化学键力和界面非极性分子色散力,它们分别对界面粘结强度的贡献,及其随等离子体处理参数的变化关系.

| Abstract: | The fiber-resin adhesion has been reinforced by plasma treatment on Ultra-high Molecular Weight Polyethylene (UHMW-PE) fibers. The mechanism of the surface change, as is reported in this paper, has been studied by the pull-out test, XPS, SEM, contact angle measurements. Giving the quantitative analysis of the applied forces affecting the surface adhesion, we discuss the roles of the three main factore playing in the fiberresin adhesion, and their relation to plasma parameters. The three main factors are the key mechanical effects, the chemical bonding effects and nonpolar dispersion force. |
