ABSTRACT

To enhance the interfacial adhesion between carbon fibre and epoxy resin matrix, phenolic resin surface treatment agent has been carried out. The influence of phenolic resin treatment agent on interfacial adhesion of carbon fibre reinforced epoxy resin composites were investigated by interlaminar shear strength, atomic force microscopy, X-ray photoelectron spectroscopy and scanning electron microscopy. The results indicated that the interfacial adhesion was improved greatly after carbon fibre treated by phenolic resin surface treatment agent.

Keywords: Interfacial adhesion, phenolic resin, surface treatment agent, carbon fibre, composites.
