The influence of temperature and matrix chemistry on interfacial shear strength in glass fibre epoxy composites
Abstract
The present work focuses on further investigating the influences of the chemistry of an epoxy system and the testing temperature on the stress-transfer capability of the fibre-matrix interface in a glass fibre-reinforced composite. We discuss how the apparent interfacial shear strength (IFSS) is influenced by the hardener-to-epoxy ratio and testing temperature. The results indicated that the IFSS was strongly dependent on both matrix chemistry and testing temperature. It was observed that the IFSS showed a significant inverse dependence on testing temperature, with IFSS dropping as the temperature was increased for all ratios. Notably it was shown that once the testing temperature was raised above the glass transition temperature (Tg) that ratios possessing excess hardener had larger IFSS values. From the results presented it is hypothesized that residual radial compressive stresses at the interface are influenced by the chemistry of the matrix system and relax away at the higher testing temperatures.
