Strength and elastic response of symmetric angle-ply carbon fibre reinforced plastics

Abstract

Comparisons between experimentally determined strengths and the theoretical predictions using four simple failure criteria are presented for symmetric angle-ply carbon fibre reinforced plastics laminates under tensile and compressive loads. The effects of non-linearity and failing strain are considered, and a correlation is given between the non-linear behaviour of unidirectional material subjected to shear and the non-linear elastic response of balanced angle-ply test specimens under tension.
