Abstract

Abstract: An epoxy-matrix composite, reinforced by CCF800H, a domestic high strength intermediate modulus carbon fiber, was prepared. A thermoplastic resin was used as the toughening agent of the resin. Effects of the content of toughening agent were investigated on the resin elastic modulus by regulating its content in the epoxy resin. Furtherly, effects of the content of toughening agent were studied on the longitudinal compressive performance of the composite. The results show that the resin modulus decreases with the increase of the thermoplastic resin content, and the Poisson's ratio of the composite increases correspondingly. The compressive strength of the carbon fiber composite decreases with the increase of the thermoplastic resin content. The thermoplastic resin content shows little influence on the compressive modulus of the composite.

Key words: epoxy resin, composites, compressive strength, Poisson's ratio
