Abstract: anical properties of laminated glass fiber plastics were examined both theoretically and experimentally. The theoretical evaluation of strength was accomplished by first expressing the stress components of the Kth constituent layer as a function of force resultants. The fracture stress of the Kth constituent layer was evaluated and the load, which would cause incipient failure of laminate, was also determined. The theoretical values were compared with experimental data obtained from the quasi-static compression test at room temperature. A delamination failure surface with shear matrix cracking was observed. In general, the theoretical and experimental results for laminate stress were in agreement.
