Temperature-dependent tensile and shear response of P100/6061 graphite-aluminumThis paper summarizes the results of an investigation conducted to characterize tensile and shear response of P100/6061 graphite-aluminum composite in the temperature range -101 to 260 C. The off-axis tension test and Iosipescu shear test methods were employed to meet this objective. The experimental results indicate that both the fiber-dominated and matrix-dominated elastic properties exhibit relatively small changes in the considered temperature range. The effect of temperature on yielding and strength, however, is significant under longitudinal and shear loading. Residual stresses play a significant role in controlling the variation of the yield stress with temperature. The observed low transverse strength of the composite is explained by interfacial defects between adjacent precursor wires induced during fabrication.
