[Abstract] To date, one of the major tasks in effective energy is to increase the wind energy's share in the world energy balances. It is expected that, by 2020, this share will be increased up to 12%. In the energy supply of rural and remote regions, the small wind energy systems can play a very important role. In order to further enable this ecologically-friendly type of energy, which is mainly focused on private customers, the energy efficiency of wind turbines needs to increase, and the cost of production of stable energy, needs to decrease, even at moderate winds. In order to achieve these goals, we propose a new material for the manufacture of turbine blades, where the reinforcing is achieved by hybrid structures containing carbon, basalt and other type of fibers. In addition, we propose modified epoxy resins to be used as matrix, containing amplifying fillers with a high modulus of elasticity in the form of ultra-dispersive powders. This presentation demonstrates the physical, mechanical and deformation characteristics of new material, as well as the results of its testing in atmospheric conditions (dry climate zone, subtropical type). The proposed time extrapolation of a wind turbine in atmospheric conditions estimated for 35 years, causes the reduction of the coefficient of operating condition of composites being considered in present work up to 0.70 °C 0.85.
