Numerical analysis is performed in order to investigate deformation behavior and strength of antisymmetric laminates under tension caused by axial load. It is determined that antisymmetric orientation of external layers of in-plane balanced laminate can be used to ensure the necessary adaptive warping and strength of composite under action of tensile stresses. The efficiency of the use of carbon and glass epoxy laminates as well as wooden laminate (birch plywood) in wind rotor blades is analysed.
