Car body manufacturing method based on carbon fiber female mold

Abstract

The invention provides a car body manufacturing method based on a carbon fiber female mold. The car body manufacturing method comprises the following steps that 1, a layer of demolding wax is appliedto the surface of the mold, after the demolding wax is solidified, a layer of demolding agent is applied to the surface of the mold, and after the demolding agent is solidified, the mold is put into avacuum bag; 2, multiple layers of reinforcing materials are added on the surface of the mold; 3, a flow guiding net layer is added on the surface of a reinforced mold A; 4, a threaded pipe is connected to the flow guiding net layer along the boundary of the mold A and connected with a glue injecting base; 5, a section of a vacuum pipe is cut off, one end of the vacuum pipe is inserted into the glue injecting base, and the other end of the vacuum pipe is inserted into a resin collector; 6, the vacuum bag is sealed with sealing glue; 7, air in the vacuum bag is extracted with a vacuum pump; 8,resin is injected into the mold; and 9, after the resin entering the mold is solidified to a carbon fiber shell, the carbon fiber shell and the mold are separated, and then a car body made of a carbonfiber material is obtained.

Description

technical field [0001] The invention relates to the field of a carbon fiber female mold material, in particular to a method for manufacturing a vehicle body based on a carbon fiber female mold. Background technique [0002] Nowadays, motorsports has become an increasingly popular sport. At present, the car body of a racing car is mainly made by anodic film vacuum blister forming technology, which is to soften the plastic PVC sheet by heating and softening The plastic PVC sheet is placed between the upper mold and the lower mold, and the vacuum equipment is turned on. At this time, the PVC sheet is pressed down and close to the upper mold and the lower mold. When molding, the PVC sheet is cooled, and finally the shaped PVC sheet is taken out. The method of making the car body by the positive film vacuum forming technology has the following characteristics: (1) The positive film vacuum forming technology has relatively high requirements on materials. When the thickness of the...

Problems solved by technology

The method of making the car body by the positive film vacuum forming technology has the following characteristics: (1) The positive film vacuum forming technology has relatively high requirements on materials. When the thickness of the PVC sheet is high, the heat treatment of the PVC sheet is difficult. , and the degree of closeness between the PVC sheet and the surface of the mold is also decreasing; (2) The positive film vacuum blister forming technology requires a high degree of vacuum. Cause the lack of smoothness of the car body; (3) The material hardness of the car body made by the positive film vacuum blister technology is relatively low, and it is easily deformed at high temperature, and the smoothness is not enough
