Caractérisation du comportement mécanique d'un composite (tissu de verre/résine époxyde) à différentes périodes de vieillissement hygrothermiques

Abstract

Characterization of the mechanical behaviour of composite

(woven fabric glass/epoxy resin) at different times during hygrothermal ageing

This paper considers the analysis of the mechanical behaviour of a laminate constituted of 12 layers of glass fiber fabric/epoxy resin conditioned at different relative humidities of 0, 60 and 96 % at 60 °C. The analysing of the experimental results obtained of hygrothermal ageing on the mechanical response has permited to show that the influence of the moisture concentration on the ultimate mechanical properties becomes significant and  important  for the composite conditioned at relative humidity of 96 % to the periods I and II (state of saturation and ageing).
