The role of residual thermal stress in interfacial strength of polymer composites by a novel single fibre technique

Research output: Contribution to conferenceSpeech

Abstract

The temperature dependence of the interfacial properties of glass fibre reinforced polypropylene and epoxy composites was investigated using a novel microbond test in the temperature controlled environment of a thermo-mechanical analyser. Highly significant inverse dependence of IFSS on testing temperature was observed in both systems. The temperature dependence of the GF-PP IFSS was accounted for by the variation of residual radial compressive stresses at the interface with the test temperature. On the other hand, it was found that the residual thermal stress did not seem to fully account for the temperature dependence of IFSS in GF-Epoxy. Nevertheless, the results clearly showed that GF-Epoxy IFSS had a strong correlation with the modulus of the epoxy matrix.
