A fundamental aspect in the wind blades design is the choice of the correct materials, because several parameters (weight, load and fatigue behaviour, physical properties, etc.) are influenced by this basic decision. Several years ago materials as varied as wood, steel and aluminium where used to produce wind blades.

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.

Wind power windmill the vertical axis blades with unique design and operation; security wind speed 60m/s,noise-free rotation; based on the principle of aerodynamics,streamling shape as wings of aero plane. in addition,the multipole design can generate high voltage even at minimum rotation speeds and realize high-power output and imprved efficiency in the range from low to …

Blades Glass fibre, with a high-density polyurethane core and a root reinforcement provides optimum strength and performance. 1 Variable Pitch Patented system allows for passive control of the angle of attack of the blades. This innovative system has 2 speeds of action: the first 30 degrees absorb wind gusts and the next 15 degrees act to limit runaway during sustained high …

Fig 2. Inside mechanical components of the nacelle in a wind turbine. Rotor blade. The rotor generates aerodynamic torque from the wind with its rotating motion as the blades spin. Optimization of the shape and material of the blades should allow for the blade to spin faster and capture wind at lower velocities to increase turbine efficiency.

A composite material consists of two or more materials combined to obtain properties different from those of the individual materials.-Reinforcing fibres (to add strength and stiffness )-Matrix (holds and protects fibres, and distributes the load) Polymer Matrix Composite (PMC) materials are typically used in wind turbine blades.

A composite material based on a continuous basalt fiber is used in the manufacturing of vertical wind turbine blades (VAWT – Vertical Axis Wind Turbines). The produced blades are light, flexible but much stronger than metal or plastic ones. Moreover, the composite material is both resistant to the adverse factors and environmentally friendly.

fibre reinforced plastics, which have proven to be optimal materials for both wind turbine blades and pipe systems on oil and gas rigs. Both now face the challenge of finding good solutions for decommissioning these materials in the coming decades. For the wind sector, that is an urgent challenge here and
