Abstract

In order to obtain information on the temperature dependence of the interfacial shear strength (IFSS) in glass fiber – polypropylene composites we have adapted a thermomechanical 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 fiber – polypropylene was measured in the range from -40°C up to 100°C. The IFSS showed a highly significant inverse dependence on testing temperature.
