摘要
Abstract
The epoxy resin matrix with different cross-linked structure was obtained by changing the ratio of the resin with different de-gree of functionality.The effects of epoxy resin with different cross-linked structure characteristics on longitudinal compressive perform-ance of domestic made T800 carbon fiber reinforced composites were studied in this paper.The results show that,with the content of the trifunctional epoxy resin increasing,the crosslinking density of resin matrix is increased,the modulus of resin matrix is increased, and the Poisson's ratio of unidirectional carbon fiber composites laminates is decreased too.It is found that the longitudinal compressive strength of carbon fiber composites is increased with the resin matrix crosslinking density increasing.The effect of crosslinking density of resin matrix on the compressive modulus of unidirectional composite laminates is not obvious.关键词
