Carbon fiber composite material hydrogen storage tank preformed body weaving forming method

Abstract

The invention discloses a carbon fiber composite hydrogen storage tank preformed body weaving forming method. The method comprises the following steps that size design is carried out according to a hydrogen storage tank preformed body, inner layer forward fiber weaving is carried out on the surface of a hydrogen storage tank core mold, then fiber winding is carried out, and reverse fiber weaving is carried out on an outer layer. The weaving process is started from the head of the hydrogen storage tank, weaving is conducted to the tail of the hydrogen storage tank for a stroke, the tail is fixed through an adhesive tape or a ribbon, then weaving is conducted again, fiber winding is conducted after the preset thickness of the inner layer is achieved, and finally reverse weaving is conducted on the wound outer layer. The hydrogen storage tank is preformed in a forward weaving-winding-reverse weaving mode, the phenomenon that fibers of a hydrogen storage tank preformed body are uneven in longitudinal and transverse stress due to single weaving or winding can be avoided, the wrapping performance of the hydrogen storage tank preformed body is improved, meanwhile, raw materials can be saved, and the weaving cost can be reduced.

Description

technical field [0001] The invention relates to a weaving and molding method for a carbon fiber composite material hydrogen storage tank preform, which belongs to the application of a carbon fiber composite material weaving molding method in the manufacturing process of a hydrogen storage tank. Background technique [0002] Hydrogen and methane are clean fuels, especially hydrogen. The product after combustion is water vapor, which will not cause pollution and harm to the environment. As a fuel, hydrogen faces a big problem in the storage of hydrogen. At present, the key problem in the use of hydrogen is to store hydrogen safely. There are three main storage methods: (1) Hydrogen storage by adsorption, mainly using hydrogen storage materials for hydrogen storage. adsorption to achieve the purpose of storing hydrogen; (2) low-temperature liquefaction hydrogen storage, this method has a large storage capacity per unit volume container, but requires a lower temperature; (3) hig...

AI Technical Summary

Problems solved by technology

The traditional hydrogen storage tank preform is wound and formed, resulting in uneven thickness of the fibers. Since carbon fiber composites are anisotropic materials, the force on the hydrogen storage tank is unbalanced, which affects the overall mechanical properties of the material.
