Problems solved by technology

However, the currently prepared glass fiber reinforced composites have disadvantages such as low bond strength and easy bubbling.
Sandwich materials mostly use honeycomb core material, wood core material, organic foam, etc., but at present, there are generally low bonding strengths between them and glass fiber reinforced composite material panels, and phenomena such as delamination occur, thereby reducing the mechanical properties of the overall car panel

Abstract

The invention belongs to the technical field of carriage plate preparation, and discloses a carriage plate and a preparation method thereof. The composite board comprises a first panel layer, a secondpanel layer, a sandwich layer and a framework supporting layer, the sandwich layer comprises a plurality of foam blocks, the framework supporting layer is latticed, the framework supporting layer isarranged between the first panel layer and the second panel layer, grids of the framework supporting layer are filled with the foam blocks, and the framework supporting layer, the first panel layer and the second panel layer are integrally formed. The preparation method comprises the following steps that a release film, first demolding cloth, a first fiber reinforced resin prepreg tape and a latticed fiber reinforced resin prepreg tape frame are sequentially laid from bottom to top; the resin foam composition is poured into a latticed fiber reinforced resin prepreg tape frame; a second fiber reinforced resin prepreg tape-second demolding cloth can be paved; and hot-pressing curing molding and demolding treatment can be carried out. The mechanical property of the carriage plate is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of carriage boards, and in particular relates to a carriage board and a preparation method thereof. Background technique [0002] With the needs of social development, automobiles have become an indispensable means of transportation for life. In order to meet the needs of high-quality life, automobile lightweight is a hot research topic in the automobile industry and new material industry. Automobile lightweight is to reduce the overall quality of the automobile as much as possible under the premise of ensuring the hardness and safety performance of the automobile, so as to improve the power utilization rate of the automobile, reduce fuel consumption, and reduce exhaust pollution. In addition, after the car is lightweight, its acceleration performance will also be improved, and due to the small inertia in the event of a collision, the braking distance will also be reduced. In addition, for e...
