Problems solved by technology

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.
However, the vehicle floor using various bamboo and wood plywood also has certain problems in its heat insulation, sound insulation, and noise insulation performance.

Embodiment 1

[0022] A floor plate for cars is one of the composite material vehicle floor plates involved in this paper. The panel 1 is formed by curing epoxy resin and carbon fiber, and the core material 2 is PVC foam. Process the corresponding mold according to the need, and treat the surface of the mold accordingly. Lay the bottom layer of carbon fiber, PVC foam, and top layer of carbon fiber on the surface of the mold, seal the mold, and fill the mold with epoxy resin. After the resin is completely cured, the composite bottom plate can be taken out, and it can meet the requirements after a little modification.

Embodiment 2

[0024] A passenger car bottom plate is one of the composite material vehicle bottom plates 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, and a platform is selected as a mold according to its needs, and the corresponding surface treatment is carried out on the mold. Lay vinyl-impregnated fiberglass on the countertop, top with balsa wood, and then 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.

Embodiment 3

[0026] A compartment floor for trucks, which is one of the composite material vehicle floors involved in this paper, its panel 1 is made of vinyl resin and glass fiber solidified, the core material 2 is foam wood, and the core material 2 is placed at intervals There are FRP square tubes 3. The bottom plate of the truck compartment is generally a large-area flat plate, which needs to be spliced ​​by multiple flat plates. Select a platform as the mold according to its needs, and carry out corresponding surface treatment on the mold. Spread the glass fiber impregnated with vinyl resin on the table top, pave paulownia wood on the surface, arrange the glass fiber reinforced plastic square tubes 3 at intervals, and spread the glass fiber impregnated with resin 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 completely cured, the required vehicle flo...

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, ...
