摘要

制备了具有环氧丙基侧链的对位芳纶（PPTA-ECH)和间位芳纶(PMIA-ECH)，并将其用做对位芳纶 (PPTA)织物/环氧树脂复合材料中PPTA织物的涂覆剂。采用场发射扫描电子显微镜(FE-SEM)及XPS等方法对PPTA织物表面的PPTA-ECH涂层结构进行了表征。考察了 PPTA-ECH和PMIA-ECH涂覆的PPTA织物/环氧树脂复合材料的层间剪切强度和面内剪切强度，并与未经涂覆的PPTA织物复合材料的性能作比较。结果表明，PPTA-ECH和PMIA-ECH可显著改善PPTA织物和环氧树脂之间的界面性能。涂覆了 PPTA-ECH及PMIA-ECH的PPTA织物/环氧树脂复合材料的层间剪切强度(ILSS)比未经涂覆的复合材料分别提高了 26. 20%和 14.76%，面内剪切强度(ISS)分别提高了 26.98%和11.86%。由于PPTA-ECH对 PPTA纤维具有更强的亲和能力，因此PPTA-ECH在层间剪切强度和面内剪切强度方面的增强效果均优于 PMIA-ECH。对PPTA-ECH在PPTA纤维表面铺展与吸附及对复合材料的增强机理也进行了初步探讨。作为新型涂覆剂，PPTA-ECH在对位芳纶复合材料的开发应用方面具有潜在的应用前景。

Abstract

Epichlorohydrin modified poly ( p-phenylene terephthamide) ( PPTA-ECH ) and poly ( m-phenylene isophthalamide) (PMIA-ECH) were prepared and used as coating agents for PPTA fabric in PPTA fabric/epoxy resin composites. Field emission scanning electron microscopy (FE-SEM)

Fourier Transform Infrared Spectroscopy (FTIR)

and x-ray photoelectron spectroscopy (XPS) were used to characterize the structure of PPTA-ECH coating on the surface of PPTA fibers. The interlaminar shear strength (ILSS) and in-plane shear strength (ISS) of composites of PPTA-ECH and PMIA-ECH coated PPTA fabric/epoxy resins were investigated

which were compared with that of the pristine PPTA fabric/epoxy resin. The results showed that the coatings of PPTA-ECH and PMIA-ECH can significantly improve the interfacial properties of PPTA fabric with epoxy resins. The ILSS values of PPTA-ECH and PMIA-ECH coated PPTA fabric/epoxy resin composites were increased by 26. 20% and 14. 76%

and the ISS values of them were increased by 26. 98% and 11. 86%

respectively

compared with that of pristine PPTA fabric/epoxy resin. The reinforcement effects of PPTA-ECH on ILSS and ISS are better than those of PMIA-ECH due to the stronger affinity of the former for PPTA fiber. The spreading and adsorption of PPTA-ECH on the surface of PPTA fibers and its reinforcement mechanism for PPTA fabric/epoxy resin composite were discussed. Thus PPTA-ECH has great potential as new coating agent for the fabrication of PPTA materials.
