Abstract
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 properties 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.
