Abstract

The present work focuses on further verification of the hypothesis that the level of apparent IFSS in glass fibre-reinforced thermoplastic composites can be modelled satisfactorily by assuming that the main component of the IFSS is actually due to a combination of thermal residual stress and static friction at the fibre-polymer interface. In order to obtain information on the temperature dependence of glass fibre - polypropylene IFSS we have adapted a thermo-mechanical analyser to enable interfacial microbond testing to be carried out in a well controlled temperature environment. Test results obtained by TMA-microbond testing showed excellent comparability with those obtained by normal microbond testing. The temperature dependence of IFSS of glass fibre - polypropylene was measured in the range from -40°C up to 100°C. The IFSS showed a highly significant inverse dependence on testing temperature.
