	The paper presents FEA numerical analysis of composite structure subjected to complex loading conditions (tension and shear) . The layered structures were characterized fro m the standpoint of optim al selection and strength parameters. Th e subject of the examin ations was a composite: glass fibre s reinforced polymers-M12/26%/TVR380R-glass prepreg system (Hexcel, R-glass fibres-undirectional, M12 epoxy resin). The composite system is use in helicopter blades. It exhibits good fatigue life and hot/wet performances up to 100ºC. The strength properties were investigated according to ISO and ASTM standards. The composites for the study were produced by autoclave technique. The Layup-Ply method with ABAQUS/Standard program was applied as an analysis tool which was ca rried out the leading of ca lculation. It was used an incremental iterative Newton-Raphson’s method in a range of nonlinear geometric. Numerical calculation was made as a part of introduction to failure analysis composite materials. The risk of laminate’s damage could be estimated as a possible appearing in dangerous points of construction. There were taken four criteria: the Maximum Stress Criterion, Tsai-Hill’s Criterion, tensor criterion of Tsai-Wu and Azzi-Tsai-Hill’s criterion.
