中文摘要：
采用多结构形态倍半硅氧烷（VMS—SSO）涂层结合等离子活化纤维表面的方法对碳纤维（CF）改性，研究了纤维表面处理对碳纤维／聚芳基乙炔复合材料界面性能的影响．结果表明，等离子活化前后纤维表面涂层处理使材料的ILSS分别提高25％和45％，在碳纤维与树脂之间引入了过渡层．等离子活化纤维在碳纤维与涂层间通过VMS-SSO引入了化学键连接．含活性官能团的多形态倍半硅氧烷涂层在等离子活化纤维前后处理碳纤维，都能提高复合材料的界面性能．但是效果不同．其原因是，碳纤维与树脂间相互作用的不同，前者主要是过渡层效应，后者在碳纤维与树脂间引入了化学键．
英文摘要：
Silsesquioxane coating was used to modify carbon fibre surface before and after plasma activation and the influence of the modification on the Interfacial Properties of CF/PAA Composites was investigated. The results showed that interlaminar shear strength of carbon fibre/polyarylacetylene composites increased to 25% and 45% before and after plasma activation. There were transitional layer between carbon fibre and polyarylacetylene resin. The silsesquioxane could improve the interfacial properities of carbon fibre/polyarylacetylene composites without or with plasma activation. The former is due to the transitional layer while the latter results from the chemical interaction between fibres and resin.
