Abstract
A simple and accurate test method is presented to investigate the influence of shear stresses on tensile failure of unidirectional carbon fibre/epoxy. Glass/carbon hybrid laminates are used to eliminate stress concentrations and avoid premature failure at the end-tabs. Free-edge delamination is suppressed using thin-plies. Angle-ply carbon/epoxy laminates have been designed to achieve combinations of tensile and shear stresses. It is shown that in-plane shear does not significantly affect the fibre failure strains.
