Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0029] like Figure 1 to Figure 4 As shown, a carbon fiber composite vehicle body of the present invention includes a vehicle body 1 and a bottom plate 2, and the bottom plate 2 is fixedly connected to the bottom of the vehicle body 1 through rivets. Both the vehicle body 1 and the bottom plate 2 are integrally formed. The outer skin 11, the sandwich layer 12 and the inner skin 13 are sequentially arranged from the outside to the inside. The inner skin 13 is bonded with a reinforcing rib 3, and the reinforcing rib 3 includes a U-shaped part and a A rectangular part consistent with the longitudinal section shape of the vehicle body 1, the two parts of the ribs 3 intersect at the lower part of the body 1; Vertical; the outer skin 11, inner skin 13, bottom plate 2 and ribs 3 are all made of carbon fiber prepreg; the sandwich layer 12 is honeycomb or fo...

Abstract

The invention discloses a carbon fiber composite vehicle body. The carbon fiber composite vehicle body comprises bodywork and a bottom plate, the bottom plate is connected with the bottom of the bodywork, the bodywork is manufactured through integral forming, the bodywork comprises an outer skin, a sandwich layer and an inner skin which are sequentially arranged from outside to inside, reinforcing ribs are bonded on the inner skin, and the carbon fiber composite vehicle body has the advantages of being high in rigidity and strength, light in mass, soundproof and heat resistant. The carbon fiber composite vehicle body is formed by connecting the bodywork which is manufactured through integral forming with the bottom plate, connecting structures of the vehicle body can be greatly reduced, the rigidity and the strength of the vehicle body are improved, and the safety of the vehicle body is facilitated. The invention further discloses a manufacturing method of the carbon fiber composite vehicle body, the degree of production integration is high, and the method has important meanings on reducing the manufacturing cost and improving the rigidity and the strength of the vehicle body.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a car body made of carbon fiber composite material and a manufacturing method thereof. Background technique [0002] The light weight of trains has important value in many aspects such as energy saving and safety. Traditional train bodies are generally made of stainless steel or aluminum alloy. Compared with them, carbon fiber composite materials have lower density, higher stiffness and strength. Therefore, the manufactured car body has lighter weight and better safety. [0003] There is currently no carbon fiber composite body on the market, nor is there a general method for making a composite body. The manufacturing and molding of carbon fiber composite materials is completely different from traditional metal materials. A reasonable molding solution will greatly reduce manufacturing costs and optimize the structure. Contents of the invention [0004] The o...
