Abstract
The degradation of glass fiber reinforced composite materials (GFRP) in hydrothermal environment is a problem to be solved in the engineering research.Artificial accelerated aging method is a good and common way to study hydrothermal aging.In this paper,two different systems of glass fiber/resin were investigated by artificial accelerated aging method combined with open water storage environment,which reinforced composite materials in the environment of 35 ℃ water immersion,65 ℃ water immersion and salt spray.The properties of mechanical,water absorption,hardness,bending strength were investigated and the service life were predicted by two models.The study shows that the hardness of the material changes obviously in the early period,and tends to be stable in the later stage.The water absorption rate almost fit the Fick law.The temperature has a significant effect on the retention rate of the flexural strength,and the salt spray is the second factor.The median aging formula has a higher fitting degree than the empirical formula,which even exceed by 7.6％.关键词
