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