Summary An advanced epoxy resin used in commercial applications has been pre-pregged with three different types of carbon fibres with differing surface finish. The interface dominant mechanical properties of the unidirectional materials have been assessed. Thus, interlaminar shear strength (ILSS), transverse strength and transverse modulus as well as unidirectional tensile strength and modulus have been measured. Single fibre fragmentation testing has been carried out using the same fibre and resin combinations. The correlation between fibre-matrix interface quality and the composite mechanical properties has been examined.
Keywords Single fibre fragmentation test, carbon fibre-reinforced epoxy, carbon fibre/epoxy composites, interlaminar shear strength, transverse strength.
