Problems solved by technology

[0003] The traditional metal gas cylinder bracket is welded by square steel profiles. The manufacturing process is cumbersome, the connection accuracy is low, and the maintenance performance is poor. Once damaged, the entire gas cylinder bracket needs to be replaced as a whole, which is costly and consumes a lot of man-hours
In addition, different cylinder brackets need to be designed for different models, the design process and assembly process are different, and mass production and processing cannot be carried out

Embodiment Construction

[0028] The invention provides a preparation process for a pultruded composite material modular gas cylinder bracket, comprising the following steps:

[0029] (1) Production module raw materials: use continuous fibers to impregnate the resin, and make the raw material 1 of the long rod-shaped gas cylinder bracket module with equal cross-section through mold pultrusion. The top surface and the bottom surface of the raw material 1 of the bottle bracket module are symmetrical up and down with the axis of the raw material 1 of the gas cylinder bracket module. The left and right sides of the top surface of the raw material 1 of the gas cylinder bracket module are both horizontal, and the top surface of the left side of the raw material 1 of the gas cylinder bracket module is provided with a first positioning piece 6, and the top surface of the right side is provided with a second positioning piece 7. The first positioning The first positioning member 6 and the second positioning mem...

Abstract

The invention discloses a preparation process of a pultrusion composite material modularized gas cylinder support. The preparation process comprises the following steps that a uniform-section long-rod-shaped gas cylinder support module raw material is obtained through pultrusion of composite material, low-cost large-scale production is achieved, a gas cylinder support module, a module base and a module top cover can be obtained through simple cutting, the gas cylinders are arranged and assembled according to the requirement of a vehicle for the number of the gas cylinders, so that the production work of the gas cylinder support can be realized, the gas cylinders with different numbers can be assembled in different forms, the design and processing links of the traditional steel gas cylinder support are omitted, the production cycle is greatly shortened, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of composite material production, and in particular relates to a preparation process for a pultruded composite material modular gas cylinder bracket. Background technique [0002] Under the call of global energy conservation and emission reduction, the lightweight development of auto parts has become an inevitable trend. The gas cylinder bracket is used for hydrogen energy trucks or passenger cars to carry hydrogen gas cylinders. The use of lightweight and high-strength composite material gas cylinder brackets to replace traditional metal gas cylinder brackets has become a key direction for the lightweight development of passenger and cargo hydrogen energy vehicles. [0003] The traditional metal gas cylinder bracket is welded by square steel profiles. The manufacturing process is cumbersome, the connection accuracy is low, and the maintenance performance is poor. Once damaged, the entire gas cylinder bracke...
