Abstract

The influence of hygrothermal environment on compressive property of woven carbon fiber epoxy resin composite was investigated via tensile and compress tests under different hygrothermal environment. Moisture absorption, tensile and compressive properties, failure modes, FTIR and dynamic mechanical property were analyzed. The results show that the moisture absorption of woven carbon fiber epoxy resin composite is not high. The hygrothermal environment has larger influence on the compressive property than the tensile property. The failure modes of composite laminate with holes are hole failure, the tensile fracture is flush, the compressive fracture has an obvious fiber push-into phenomenon of the hole sides. There is no new peak in FTIR after moisture absorption, representing that no chemical reaction occured of the epoxy resin. The glass transition temperature Tg of the composite after moisture absorption is 173 C, which fells 14 C than the dry counterpart.
