Abstract

Abstract: Hygrothermal ageing test of carbon fiber composites were carried out with three temperature conditions of 40 ℃, 60 ℃ and 80 ℃ in 90%RH, and dynamic and mechanical properties of the composites were tested. Based on the results of SEM, mechanical characteristics,IR and DSC, two kinds of hygrothermal ageing models were selected, then formulas of two hygrothermal ageing models were proposed in 90%RH after parameters were calculated. The results show that the dynamic model should be chosen in the conditions with different temperatures, while the residual strength model should be chosen in the conditions with extended time variable.

Key words: carbon fiber, composite materials, hygrothermal ageing, aging model
