抄録

<p>In the present study, a matrix stress-strain relationship is calculated from the off-axis stress-strain relationship of CF/PP laminates by inverse analysis based on Eshelby model combined with Mori-Tanaka theory. Then, the stress-strain relationship and yield shear stress at various temperatures is estimated by viscoelastic characteristic. Next, the temperature dependence of strength and strength variation of unidirectional CF/PP are predicted from the matrix yield shear stress and Weibull distribution using the extended GLS model, which takes into account the existence of initial defects. Comparison of the predicted strength of CF/PP with the test results in previous studies shows the validity of the prediction method of the temperature dependence of strength by the extended GLS model.</p>
