Abstract
This paper describes a method of calculating the water content of a composite material as a function of ageing and the degree of damage. The material studied is a glass fibre/epoxy laminate. Tubular specimens were manufactured by filament winding. The mechanical damage was created by tensile fatigue tests. Once damaged, the specimens were aged in demineralized water at 60°C. The paper describes the results of ageing tests on virgin and damaged material. The parameters of the Langmuir model and the diffusion law are determined. The water content in the damaged material can be calculated from the increased rate of absorption. The paper also proposes a model of the phenomena based on this principle.
