Rail transit carbon fiber composite vehicle lower outer cover and manufacturing method

Abstract

The invention relates to a rail transit carbon fiber composite vehicle lower outer cover and a manufacturing method. The lower outer cover structurally comprises an outer cover main part, a metal embedded part, an outer cover auxiliary part and 3K appearance fabric, and the metal embedded part is embedded in the outer cover main part; the outer cover main part and the outer cover auxiliary part are integrally formed by adopting a carbon fiber material, the outer cover main part and the outer cover auxiliary part are bonded into a whole, and 3K appearance fabric is bonded on the whole outer surface after the outer cover main part and the outer cover auxiliary part are bonded into a whole. The lower outer cover is a rail transit appearance decoration assembly which is formed by a carbon fiber composite material through autoclave external curing forming and machining appearance combination. The lower outer cover is wide in application range, simple in structure and easy to manufacture and implement, has the light-weight effect and has the advantages that the appearance of the texture of the carbon fiber cloth is consistent, the functional requirement is met, and meanwhile the manufacturing cost is greatly reduced, and the manufacturing period is greatly shortened.

Description

technical field [0001] The invention relates to an under-vehicle cover structure and a manufacturing method, in particular to an under-vehicle cover of rail transit carbon fiber composite material and a manufacturing method with wide application range, simple structure, simple manufacture and simple implementation. Background technique [0002] With the increasing frequency of economic and trade exchanges around the world and the gradual improvement of urbanization, high-speed railways have entered a new round of rapid development. Providing passengers with safer, faster, more comfortable and more environmentally friendly transportation services is the eternal theme of train design . The world's rail transit equipment is facing new challenges: how to achieve lightweight, reduce wheel and rail wear and motion resistance, and reduce maintenance costs; integrate functions, simplify manufacturing, reduce materials, and reduce costs; meet anti-corrosion, flame-retardant, sound in...
