Problems solved by technology

[0002] At present, most of the blades used in wind power generation equipment in the world use FRP as the main structure, but for blades with a length of more than 30 meters, it is usually necessary to add expensive carbon fiber to make up for the lack of material stiffness, which undoubtedly increases production. The cost of manufacturing, the production cycle is long, and the waste products in the manufacturing process of such blades and the damaged products after use are not easy to recycle, and random discarding will definitely cause environmental pollution, making it costly to dispose of these waste products and damaged products reasonably manpower and material resources

Abstract

The invention discloses a bamboo-made composite material wind power vane and a vacuum infusion technique. According to the technique scheme provided by the invention, the bamboo-made composite material wind power vane comprises a vane body which is composed of a vane-shaped upper vane and lower vane, wherein the vane root is arranged at the root part of the vane body, the top end of the vane body is a vane tip, the upper and the lower vanes are adhered into an integral by mold adhesive bar and makes the periphery form a cavity, a bamboo cordwood is filled in the vane root and / or upper vane and / or lower vane, a vane root premolding part is arranged on the bottom end corner of the vane outer-boundary of the vane body. The vane is prepared by each procedure such as preparing equipment material, preparing mould, paving each kind of material, laying out tube, infusing, doing subsequent process and the like. The vane is low in preparation cost, short in preparation period, which is beneficial to protect environment, easy to control the preparation procedure and obtain raw materials.

Description

technical field [0001] The invention discloses a wind turbine blade made of bamboo composite material and a vacuum infusion process of the wind turbine blade made of bamboo composite material. Background technique [0002] At present, most of the blades used in wind power generation equipment in the world use FRP as the main structure, but for blades longer than 30 meters, it is usually necessary to add expensive carbon fiber to make up for the lack of material stiffness, which undoubtedly increases production. The cost of manufacturing, the production cycle is long, and the waste products in the manufacturing process of the blades and the damaged products after use are not easy to recycle. Random discarding will definitely cause environmental pollution, making it costly to dispose of these waste products and damaged products reasonably human and material resources. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in t...
