Abstract
The invention discloses a fiber layering method for manufacturing wind power blades, which mainly includes laying multi-layer fiber layers in the mold of wind power blades, each fiber layer is composed of a plurality of spanwise fiber cloths and a plurality of chord direction fiber cloths overlap each other. Among them, the spanwise fiber cloth is laid in the first area of the wind power blade mold, and the laying direction of the spanwise fiber cloth is consistent with the span direction of the wind power blade mold, and multiple pieces of spanwise fiber cloth overlap each other. In the second area of the wind power blade mold, chord fiber cloth is laid. The laying direction of the chord fiber cloth is consistent with the chord direction of the wind power blade mould. Multiple pieces of chord fiber cloth overlap each other. Lap each other to the fiber cloth. By adopting the above method, it is possible to simultaneously solve the problem that it is difficult to balance laying difficulty and laying efficiency when wind power blades are produced by spanwise or chordwise layup.
Description
technical field [0001] The invention relates to a fiber lay-up method for manufacturing wind power blades. Background technique [0002] As a high-quality renewable energy, wind energy is an effective way to deal with climate and environmental issues. Wind power blades, as the core components of wind turbines, are rapidly developing towards the direction of large-scale blades. After the blade size becomes larger, the manufacturing difficulty of the composite material blade also rises sharply. In the area where the height and curvature of the blade mold change greatly, it is difficult for construction personnel to reach, and the manual laying of fiber reinforced materials is difficult, and special tooling is required to assist in laying. [0003] In the production process of wind turbine blades, the following two methods are generally used to lay fiber cloth. One method is that the laying direction of the cloth is all consistent with the span direction of the blade. This m...
