Problems solved by technology
The multi-cavity reinforced structure has been widely used in aviation, but the multi-cavity structure in aviation is mostly formed by rubber mandrel. The cost of the rubber mandrel is high. If the low-cost metal mandrel is used directly, it is difficult to demould. risks of
[0003] Therefore, how to provide a method for preparing a composite car body skirt, which can reduce the cost and avoid the problem of difficult demoulding during the molding process, is urgently needed by those skilled in the art.

The invention relates to a preparation method of a composite material vehicle body skirt plate. The preparation method comprises the following steps that S100, a skirt plate body is integrally formedby adopting an OoA forming process, and the skirt plate body comprises a shaft hole part and a multi-cavity structure; S200, an end sealing piece is fixed to the end of the multi-cavity structure in asealed mode, and the skirt plate body is machined to form mounting structures used for mounting skirt plate accessories; and S300, the skirt plate accessories are correspondingly mounted and fixed tothe mounting structures correspondingly. According to the preparation method, the manufacturing cost of the composite material vehicle body skirt plate can be reduced, and the problem that demoldingis difficult in the forming process can be avoided.
Description
technical field [0001] The invention relates to the technical field of composite material molding, in particular to a method for preparing a composite material car body skirt. Background technique [0002] Composite car body skirt panels mostly adopt a sandwich structure. The core material of the sandwich structure is easy to debond from the skin. After the skin is damaged, water vapor easily enters the interior of the core material, which accelerates the damage of the structure. The multi-cavity reinforced structure has been widely used in aviation, but the multi-cavity structure in the aviation is mostly formed by rubber mandrel, the cost of the rubber mandrel is high, if the low-cost metal mandrel is used directly, it is difficult to demould risks of. [0003] Therefore, how to provide a method for preparing a car body skirt made of composite material, which can reduce the cost and avoid the problem of difficult demoulding during the molding process, is urgently needed b...
