摘要: 将碳纤维预浸芳基乙炔后进行空气等离子处理,使芳基乙炔接枝在碳纤维上,并用扫描电镜、红外光谱、紫外光谱、X射线衍射、拉曼光谱等多种方法进行研究。结果表明经过等离子处理以后的碳纤维/芳基乙炔复合材料的层间剪切强度(ILSS)最大可提高12.4%,而碳布接枝了PAA单体以后,可使复合材料的层间剪切强度最大提高到51.27%。

Abstract: Carbon fiber was treated with plasma technology after dipped with polyarylacetylene(PAA) monomer, which enables PAA monomer to graft on the fiber. Interface characterizations of carbon fiber reinforced polyarylacetylene composite were studied by the aid of scanning election microscope, infrared spectra, ultraviolet spectra, X-ray diffraction spectra, Raman spectroscopy, etc. The results showed that the interlaminar shear strength (ILSS) of C/PAA composite was improved by 12.4% after carbon fiber was treated with plasma technology and improved by 51.27% after the fiber grafted with PAA monomer.-
