Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] Such as Figure 1 to Figure 10 The composite car roof shown includes a roof main body 1, a front windshield mounting hole 6 is provided on the front edge of the roof main body 1, and a hinge mounting hole 4 is provided on the rear edge of the roof main body 1. The top cover main body 1 sequentially includes an inner layer 16, an intermediate layer 15 and an outer layer 14 from the inside to the outside, and the layers are formed by compression molding. The outer layer 14 is made of carbon fiber composite material, so that the top cover not only meets the requirement of light weight, but also has the texture of carbon fiber cloth, which improves the appearance quality. The middle layer 15 is made of glass fiber composite material; it can reduce the weight of the top cover. The inner layer 16 is made of glass fiber composite material, which can reduce the weight of t...

Abstract

The invention discloses a composite material automobile top cover which comprises a top cover main body, wherein front windshield mounting holes are formed in the front edge of the top cover main body; hinge mounting holes are formed in the rear edge of the top cover main body; the top cover main body comprises an inner layer, a middle layer and an outer layer in sequence from inside to outside; all the layers are pressure-molded; the outer layer is made of a carbon fiber composite material; the middle layer is made of a glass fiber composite material or the carbon fiber composite material or a glass fiber and carbon fiber hybrid composite material; the inner layer is made of the glass fiber composite material or the carbon fiber composite material or the glass fiber and carbon fiber hybrid composite material; inwards protruded reinforcing blocks are arranged between the outer layer and the middle layer, or between the middle layer and the inner layer; the reinforcing blocks are high-intensity sheet foam. According to the composite material automobile top cover, the preparation and assembling procedures of the top cover can be simplified, and the effect of light weight is achieved; furthermore, the composite material automobile top cover has a carbon fiber cloth textured appearance.

Description

technical field [0001] The invention belongs to an automobile top cover, in particular to a composite material automobile top cover. Background technique [0002] The car roof is a large-scale cover. The current car roof is mainly made of steel. The manufacturing needs to go through stamping, welding, painting and other processes. The process is complicated and the process is long, and the steel car roof is heavy. With the increasingly stringent national fuel consumption and environmental protection regulations, lightweight has become an inevitable trend in the development of automobile technology. Due to the low density of composite materials, which is 1 / 4 of that of steel, the specific stiffness and specific strength are high. Composite materials are used to manufacture automobile roofs It has become one of the main technologies to realize the lightweight of the whole vehicle. As CN202847821 U discloses a kind of novel composite material car roof, this car roof is connect...
