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).
