Study of Wettability of Vinyl Resin on Carbon Fiber

摘要

The tensile performance of the vinyl resin casting body, epoxy resin casting body, carbon fiber(CF) reinforced vinyl composites and CF/epoxy composites has been presented. The morphology of tensile fracture surface of CF/epoxy and CF/vinyl has been compared, and the interface adhesion has been analysed. The results show the tensile strength for vinyl resin casting body is lower than epoxy resin casting body's, the tensile modulus of them are close. But the tensile strength and modulus of CF/vinyl composites are both close to CF/epoxy composites. And the vinyl has the better interface adhesion and wettability on CF than epoxy.
