Abstract
The impact fatigue tests were performed on glass-cloth reinforced epoxy resin laminates at various temperatures up to 200°C. From the experiments, the temperature-dependence of impact fatigue strength was clarified. The scatter of this strength at each temperature was statistically analyzed and its temperature-dependence was also clarified. The safety factor and the allowable stress for the laminates under service impact loads were. studied with regard to the influence of circum-temperature used, on the basis of reliability theory. The results obtained are as follows:<br>(1) The impact fatigue strength σt of the laminates shows a scatter of logarithmic distribution at high temperatures and can be estimated statistically by the formula of σtNfmt=DtμtStu.<br>(2) The parameters of impact fatigue property, mt and Dt, and the strength scatter St are dependent upon temperature. Both of mt and Dt can be estimated from the statistic (σB, SσB) of static tensile strength σB at room temperature (20°C).<br>(3) The safety factor and the allowable stress of the laminates under service impact loads can be determined according to the expectative reliability with regard to the circum-temperature practically used. This result is very useful for the optimum structural design.
