Example Embodiment

[0021] Example 1

[0022] A floor for a car, which is one of the composite material vehicle floor involved in this article, the panel 1 of which is made by curing epoxy resin and carbon fiber, and the core material 2 is PVC foam. The corresponding molds are processed according to the needs, and the mold surfaces are treated accordingly. The bottom layer carbon fiber, PVC foam, and top layer carbon fiber are respectively laid on the surface of the mold, the mold is sealed, and the epoxy resin is filled into the mold. After the resin is completely cured, the composite base plate can be taken out and it can meet the requirements after a little modification.

Example Embodiment

[0023] Example 2

[0024] A passenger car floor is one of the composite vehicle floorboards involved in this paper. The panel 1 is formed by curing vinyl resin and glass fiber, and the core material 2 is Balsa balsa wood. The bottom plate for passenger cars is generally a flat plate. According to its needs, a platform is selected as a mold, and the mold is subjected to corresponding surface treatment. Lay the vinyl-impregnated fiberglass on the countertop, top it with Balsa wood, and again with the resin-impregnated fiberglass. After the laying is completed, the test piece is sealed, and the excess resin is extracted. After the resin is completely cured, the required vehicle floor can be formed.

Example Embodiment

[0025] Example 3

[0026] A compartment floor for a truck, which is one of the composite vehicle floorboards involved in this document, wherein a panel 1 is made of vinyl resin and glass fiber cured, a core material 2 is made of foam wood, and the core materials 2 are placed at intervals in the middle There are FRP square tubes 3. The floor of the carriage for a truck is generally a large-area flat plate, which needs to be spliced ​​several times. According to its needs, a platform is selected as a mold, and the mold is subjected to corresponding surface treatment. The glass fiber soaked with vinyl resin is spread on the countertop, paulownia wood is spread on the surface, glass fiber reinforced plastic square pipes 3 are arranged at intervals, and the glass fiber soaked with resin is spread again. After the laying is completed, an appropriate amount of pressure is applied to the surface of the specimen to ensure its molding quality. After the resin in the test piece is com...

Abstract

The invention discloses a novel composite material vehicle soleplate, which comprises surface plates (1) and a core material (2). The vehicle soleplate is characterized in that: the surface plate (1) is made of a fiber material, while the core material (2) is made of a light material; the surface plates (1) are arranged on the upper surface and the lower surface of the core material (2); and the surface plate (1) is glued with the core material (2) through the curing of resin. Moreover, the middle of the core material (2) can also be provided with a glass reinforced plastic pipe which can be a rectangular pipe (3) or a round pipe (4), thereby increasing the bearing capacity of the composite material vehicle soleplate. The composite material vehicle soleplate has light weight and can reduce the weight of a vehicle; meanwhile, the soleplate has excellent heat-preservation and heat-insulation performances, energy conservation and environmental protection; moreover, the soleplate also has better vibration-isolation and sound-insulation performances and can improve the riding comfort of a passenger. The novel composite material vehicle soleplate can be widely used as soleplates of various sedans, coaches and freight wagons.

Description

technical field [0001] The invention relates to a composite material vehicle bottom plate, which belongs to the field of vehicle manufacturing. Background technique [0002] The floor is an important part of various vehicles and is one of the main load-bearing parts of the vehicle. In the current vehicle manufacturing industry, the main materials of the vehicle floor are metal materials such as steel and aluminum alloy, and plywood materials such as wood plywood and bamboo plywood. [0003] However, the vehicle floor plates made of the above-mentioned materials all have the following defects and deficiencies. The vehicle floor adopts an all-metal structure. The metal structure has light corrosion resistance and heavy weight. The sound insulation, noise insulation, and vibration isolation performance are poor, and the thermal insulation performance is not ideal. And the vehicle floor that adopts various bamboo-wood plywoods also has certain problems in its heat insulation, ...
