Composites are a group of materials applied more extensively in aviation constructions. Their good physicalchemical and mechanical properties, and particularly from the ratio of strength to low density give a dominant place for applying in thin- walled constructions as a load carrying-capacity structure. One of the most effort parts of the helicopter is the thin-walled structure of rotor blade. The numerical calculations are a very helpful tool for solutions and analysis of materials. In this paper was presented the preliminary analysis of the effort of composite materials. Then it was possible to identify the region where is the high risk of failure in load-carrying capacity structure. The numerical tool applied to the analysis was the ABAQUS/Standard program. The estimation of the level of effort in the composite materials in the performed studies were the maximum stress criterion, the Tsai-Hill criterion, the tensor Tsai-Wu criterion and the Azzi-Tsai-Hill criterion. The mechanical properties required for analysis were performed in the way of experiments way, according to the standard specifications for this type of materials. FEM analysis was shown the effort elements of the construction, where were the highest level of tension stresses.
