Abstract
The strength of unidirectional carbon-fibre epoxy laminates has been m easured for combined compression and shear loading. Failure was by pla stic microbuckling. The axial compressive strength decreased linearly to zero as the shear stress parallel to the fibres was increased from zero to the shear strength. These experimental results support the pre dictions of Budiansky and Fleck and suggest an average fibre misalignm ent angle of 2-degrees-3-degrees.
