Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0029] figure 1 It is a flow chart of a method for manufacturing a rear floor beam provided by an embodiment of the present invention, as shown in figure 1 As shown, the method includes:
[0030] Step 101: laying the first glass fiber layer in the mold, the laying angle of the first glass fiber layer is 0°.
[0031] In step 101, the ply angle of the first glass fiber layer is set to 0°, wherein the ply angle of 0° indicates that it is laid along the fiber direction, and this kind of ply angle can make the strength of the first glass fiber layer reach the highest and improve tensile properties.
[0032] Step 102: Form 12 carbon fiber prepreg layers on the first glass fiber layer.
[0033] Among them, the ply angles of the 12 layers...

Abstract
The invention discloses a production method of a rear floor beam, which comprises the following steps of: laying a first glass fiber layer with a laying angle of 0 degree in a die; forming 12 layers of carbon fiber prepreg layers on the first glass fiber layer, wherein the laying angles of the 12 layers of carbon fiber prepreg layers are 0 degree, 45 degrees, 45 degrees, 45 degrees, 45 degrees, 90degrees, 90 degrees, 45 degrees, 45 degrees, -45 degrees, -45 degrees, and 0 degree or 0 degree, 45 degrees, 45 degrees, -45 degrees, -45 degrees, 90 degrees, 90 degrees, 45 degrees, 45 degrees, -45degrees, -45 degree, and 0 degree; laying a second glass fiber layer with a laying angle of 0 degree on the 12 layers of carbon fiber prepreg layers; carrying out press forming to obtain a rear floorbeam body; a connecting plate is arranged on the rear floor beam body to obtain the rear floor beam. According to the invention, the corrosion resistance, friction resistance and high temperature resistance of the rear floor beam can be improved, and the strength of the rear floor beam can be enhanced and the rear floor beam can be lightened.
Description
technical field [0001] The invention relates to the technical field of automobile body structures, in particular to a method for manufacturing a rear floor beam. Background technique [0002] The car floor is the main load-bearing part of the car body. Usually, the car floor is required to have the performance of anti-vibration, sound insulation and anti-corrosion. The car floor beam is a component welded on the car floor to improve the strength of the car floor. Automotive floor beams include various reinforcement beams such as rear floor beams, front floor beams, and floor connecting beams. For the rear floor beam, it is usually required to be able to better resist the deformation of the automobile floor caused by the collision, and also need to have a certain anti-corrosion performance. [0003] The current rear floor beams are all made of steel and stamped and formed. [0004] In the process of realizing the present invention, the inventor finds that there are at leas...
