This work investigates the combined effect of water immersion and temperature on interlaminar shear static fatigue strength glass fiber epoxy composites. Interlaminar tests were performed I-beam shaped samples which enable faster fluid saturation at 20, 40 60 °C, both in air immersion. Analysis parameters optical micrography enabled understanding phenomena that govern degradation for each case. The dry properties are dominated by matrix resistance room fiber/matrix interface higher temperature. immersed degradation. An analytical model based Arrhenius theory is presented building a mastercurve accounts modelled accounting change transition material. results show describes well conditions tested, provided material remains below its
