EN The paper presents FEA numerical analysis of composite structure subjected to complex loading conditions (tension and shear). The layered structures were characterized from the standpoint of optimal selection and strength parameters. The subject of the examinations was a composite: glass fibres reinforcedpolymers-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 100° C. The strength properties were investigated according to ISO and ASTM standards. The composites for the study were pro duce d by autoclave technique. The Layup-Ply method with ABAQUS/Standard program was applied as an analysis tool which was carried out the leading of calculation. 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-HiU's criterion.
