Abstract
The in-plane shear and transverse properties are measured for T800-924 C carbon fibre reinforced epoxy unidirectional material. Non-linearity in the shear response is ascribed partly to plasticity and partly to micro-crack growth within the matrix. The stress-strain response under proportional and non-proportional stressing supports the use of a def ormation theory of plasticity. A failure envelope is measured and pres ented in both stress space and in strain space for the composite; fail ure is associated with distributed tensile micro-cracking within the m atrix.
