Uniformly loaded, simply supported and clamped, antisymmetric cross- and angle-ply strips fabricated from GFRP and CFRP materials are analysed in order to quantify the influence of the in-plane fixity on the initial flexural failure loads and associated strip deflections. The initial failure response is found to be independent of the in-plane fixity for clamped cross-ply, and simply supported and clamped angle-ply strips. In the case of simply supported cross-ply strips it is shown that the in-plane boundary condition has a substantial effect on the initial failure response.
