he influence of crosshead velocity and in-situ environmental conditioning i.e. high temperature and cryogenic temperature on micromechanical performance of glass fiber/epoxy, carbon fiber/epoxy and Kevlar fiber/epoxy polymer composites has been studied. 3-point short beam shear tests were
conducted on the conditioned specimens to evaluate the interfacial properties and failure modes which are related to mechanical properties of the composites. The effect of crosshead velocity (within the range 1-103 mm/min) on the interlaminar shear strength (ILSS) of all the three composite systems at different temperatures was studied. The glass transition temperature (Tg) of conditioned samples was measured by differential scanning calorimetry (DSC) in the ¬¬¬temperature range of 25°C to 150°C temperature. At 1 mm/min loading rate, for both glass/epoxy and carbon/epoxy composites the maximum increase in ILSS value was about 85.72% with respect to ambient, while for Kevlar/epoxy composite 31.77% reduction in ILSS was observed at -100°C temperature.
