Problems solved by technology

However, the traditional steel roof cover is the heavier part of the body parts. The weight of an ordinary A-class car without a sunroof is generally about 10 kilograms (kg), which has a certain limiting effect on reducing fuel consumption.
In addition, the heavy weight also brings a lot of inconvenience to the manufacture and assembly of the roof cover

Embodiment 1

[0033] According to one aspect of the present invention, there is provided a roof cover, such as Figure 1~3 Shown, this roof cover includes:

[0034] A roof cover body 1 and a reinforcement 2, the reinforcement 2 is press-fitted inside the roof cover body 1;

[0035] Wherein, the roof cover body 1 includes a plurality of single-layer continuous carbon fiber prepregs 3 of the first structure, and the single-layer continuous carbon fiber prepregs 3 of the first structure are stacked in sequence, and adjacent to the first The radial weaving directions of the single-layer continuous carbon fiber prepreg 3 of the structure are different;

[0036] The reinforcing member 2 includes a plurality of single-layer continuous carbon fiber prepregs 3 of the second structure, and the plurality of single-layer continuous carbon fiber prepregs 3 of the second structure are stacked in sequence, and the adjacent single-layer carbon fiber prepregs of the second structure The radial knitting di...

Embodiment 2

[0047] According to another aspect of the embodiments of the present invention, a method for processing a roof cover is also provided, such as Figure 4 As shown, the method includes:

[0048] Step S41 , immersing the carbon fiber cloth in a prepreg solution with a predetermined viscosity to form a single-layer continuous carbon fiber prepreg 3 with a third structure.

[0049] Among them, the continuous carbon fiber tow can be made into radial-woven carbon fiber cloth, or the carbon fiber woven cloth sold in the market can be directly purchased. Thereafter, the carbon fiber cloth is dipped into the prepreg solution to form a single-layer continuous carbon fiber prepreg cloth 3 having a third structure in the original shape.

[0050] Optionally, the prepreg solution is an unsaturated polyester resin solution. Therefore, the thickness of the single-layer carbon fiber prepreg cloth of the third structure can be controlled at 0.2 mm by adjusting the viscosity of the unsaturated p...

Abstract

The invention provides a car roof cover and a machining method for the car roof cover. The car roof cover comprises a car roof cover body and a reinforcing part. The reinforcing part is pressed into the car roof cover body. The car roof cover body comprises a plurality of pieces of single-layer continuous carbon fiber preliminary-immerged cloth of first structures. The multiple pieces of single-layer continuous carbon fiber preliminary-immerged cloth of the first structures are sequentially overlapped and laid. The warp knitting directions of every two adjacent pieces of single-layer continuous carbon fiber preliminary-immerged cloth of the first structures are different. The reinforcing part comprises a plurality of pieces of single-layer continuous carbon fiber preliminary-immerged cloth of second structures. The multiple pieces of single-layer continuous carbon fiber preliminary-immerged cloth of the second structures are sequentially overlapped and laid. The warp knitting directions of every two adjacent pieces of single-layer continuous carbon fiber preliminary-immerged cloth of the second structures are different. According to the car roof cover, the structure of laying the single-layer continuous carbon fiber preliminary-immerged cloth in a multi-angle mode is adopted, the performance design requirement of the car roof cover is met, and the unit-price weight is optimized.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to a roof cover and a processing method for the roof cover. Background technique [0002] With the development of the automobile industry, the mandatory regulations on fuel consumption limit values ​​for passenger cars are becoming more and more stringent. 5.0L / 100km for 2020. However, the traditional steel roof cover is the heavier part of the body parts. The weight of an ordinary A-class car without a sunroof is generally about 10 kilograms (kg), which has a certain limiting effect on reducing fuel consumption. In addition, the heavy weight also brings a lot of inconvenience to the manufacture and assembly of the roof cover. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a car roof and a processing method for the car roof, which adopts a multi-angle laying structure of a plurality of single-layer continuou...
