Lightweight improvement processing process for automobile brake pad

Abstract

The invention discloses a lightweight improvement processing process for an automobile brake pad. By means of shapes and structures of parts, a lightweight gasket and a brake pad of the technology and performance can be achieved. Warpage or deformation caused by thermal contraction cannot occur for the gasket even if CFRP is used. Due to the fact that long fiber materials are adopted, the long fiber can be metal and can also be other materials, the long fiber can be stretched and fixed to other parts (such as a gasket metal plate or a friction material block) to be heated and pressed into a whole, and the long fiber forms a mesh-shaped or interwoven structure; and during thermal deformation, even if surrounding resin shrinks, the long fiber will not shrink, in this way, the resin combined surrounding the long fiber can also be fixed, and the gasket will not warp or deform. When the disk-shaped brake pad is used, the specifications of bonding area and the high strength can be met at the same time; and meanwhile the disk-hasped brake pad can meet the strength requirements of an existing disk-shaped brake pad and also meets the energy-saving and environmental-friendly requirements of vehicles.

Description

technical field [0001] The invention relates to the technical field of production and processing of automobile brake pads, and more specifically, the invention particularly relates to a lightweight and improved processing technology for automobile brake pads. Background technique [0002] Brake pads are also called brake pads or brake pads. In the braking system of a car, brake pads are the most critical safety parts and play a decisive role in the braking effect. Brake pads are generally made of steel plates, adhesive insulation layers and friction The friction material is composed of a block, and the friction material is composed of reinforcing fibers, organic materials, and friction adjustment materials, and is fixed to the lining with an adhesive. The solvent-based adhesive of heat-reactive resin is sprayed or coated on the lining and then dried, or an adhesive film is sandwiched between the lining and the friction material block, and the friction material is fixed on th...

AI Technical Summary

Problems solved by technology

[0005] However, due to the difference in elastic modulus between CFRP and the steel plate in the above-mentioned fixing method of CFRP and the steel plate, when the liner is cooled to a range close to the ambient temperature, the steel plate will be warped and deformed due to the thermal contraction of the CFRP, and its microscopic nature is currently Fiber-reinforced resins generally use short fibers or particles, without stretching or relying on each other, and warping problems will occur when heat shrinks

If the aforementioned problems do not occur, the thickness of the steel plate needs to be increased, so the purpose of reducing the lining cannot be achieved
