Embodiment 1

[0034] The manufacturing process of the carbon tube in the bamboo composite wind generator blade of the present invention adopts the following process steps:

[0035] 1. Equipment and material preparation:

[0036] According to the conventional infusion process, the required size and shape of carbon tubes are equipped with moulds, vacuum pumps, air compressors, and vacuum gas storage tanks; materials: carbon fiber cloth, matrix materials and various paving materials are used for organic materials.

[0037] 2. Prepare the mold:

[0038] (a), prepare the mandrel 3 and the upper and lower female molds 1, 6; first remove the impurities on the surface of the mandrel 3, so that the surface of the entire mandrel 3 is smooth; clean the upper and lower female molds 1, 6, and wipe the mold cleaner on the surface , Release agent.

[0039] (b), fix the mandrel 3: wrap the sealing material 2 with silicone liquid and wrap it outside the mandrel 3. After the liquid silica gel is cured, a l...

Abstract

The invention relates to a process for manufacturing a carbon tube in a blade of a wind turbine with bamboo compound material, which belongs to a technical field of the processing of the blade of the wind turbine. The process for manufacturing the carbon tube in the blade of the wind turbine with the bamboo compound materials is characterized in that a mandrel is adopted to support on a clamp which is clamped and fixed by a clamp head; a layer of sealed material is firmly wrapped outside the mandrel; a ply material is wrapped between the sealed material and a female die and a pipe work instillation is arranged outside the ply material; the two ends of the pipe work are sealed by sealed glue so that the ply can be sealed inside the pipe work so as to form a sealed space; the female die is firmly pressed outside the ply and fixed and formed through vacuum instillation matrix epoxy resin. In the process for manufacturing the carbon tube in the blade of the wind turbine with the bamboo compound material, high requirement is needed for the shape and size of the carbon tube; an irregularly shaped hollow shell forms through vacuum instillation process in one time and no mechanical process is required and the process can meet the requirements of surface precision, shape and size and application performance as well as high strength.

Description

technical field [0001] The invention relates to a manufacturing process of a carbon tube in a wind-driven generator blade made of bamboo composite material, and belongs to the technical field of wind-driven generator blade component processing. Background technique [0002] The blade prefabricated carbon tube is used to be installed in the blade tip of the wind turbine blade, and the inside of the carbon tube passes through the transmission part (shaft) of the blade brake system. Its dimensions, surface accuracy and strength requirements are high. In the existing technology, the prefabricated carbon tubes in the wind turbine blades are mainly made of organic carbon fiber cloth as the base material, and after being infused with epoxy resin, they are cooled and solidified; deal with. Due to the high requirements on its outer surface and external dimensions, conventional mechanical processing methods will destroy the mechanism of the material and cannot meet the requirements ...
