Study on the Behavior of Accelerated Ageing Fabric-Reinforced Epoxy Composites

摘要

This paper presents an experimental investigation result of the effects of accelerated ageing upon the hygrothermal flexural and interlaminal shear properties of a graphite fabric-reinforced epoxy matrix that cured at moderate temperature. Two common used accelerae ageing methods that are either immersing specimens in water at temprature up to boiling point for 48 hours or exposing specimens in a hot-wet chamber in which the temprature and relative humidity were kept constantly at 70 deg C and 100
