Embodiment Construction

[0032] The heavy-duty truck brake pad with "artificial bone" as the skeleton is a special brake pad developed for heavy-duty trucks with high strength, high wear resistance, high shock resistance, high temperature resistance and low noise. Using carbon fiber / silicon carbide ceramic matrix composite material to make a multi-hole skeleton, and using ultrasonic assisted filling technology to develop a new type of truck brake pads, to meet the specific power, load and braking needs of the truck braking system, with high strength, durability It has outstanding advantages such as high temperature and long service life, especially high and stable friction coefficient, and is not sensitive to environmental influences.

[0033] The porous "artificial bone" skeleton is prepared by hot pressing-sintering-desolvation method. Using limestone as a porogen, carbon fiber is impregnated through a slurry container containing ultra-fine matrix ceramic powder, and then the fiber impregnated with ...

Abstract

The invention relates to the field of manufacturing of heavy trunk brake pads, in particular to a heavy truck brake pad with a man-made skeleton as a framework and a manufacturing method of the heavy truck brake pad. The porous man-made skeleton framework is made of carbon fiber toughened ceramic, a porous framework material is filled with resin, friction performance modifier, filler and the like to make a high-performance special brake pad friction material, and thus the heavy truck brake pad can adapt to a special working environment and has the advantages of being low in density, high in strength, good in heat resistance, high in friction coefficient, stable and long in service life. The heavy truck brake pad can adapt to extreme working conditions with high temperature and high loads, is suitable for high-speed heavy trucks, lifting devices for mines and the like and has huge promotional application values.

Description

technical field [0001] The invention relates to a manufacturing process and method of a heavy-duty truck brake pad, in particular to a heavy-duty truck brake pad with an "artificial bone" as a skeleton and a preparation method thereof. Background technique [0002] Heavy-duty trucks are characterized by high load, large capacity, frequent starting, low-speed driving, and frequent emergency braking. They are "high-tech" products in the braking system. The composition of the friction material used in traditional brake pads is called "ternary structure", that is, resin, reinforcing material and friction performance regulator. The actual composition of today's friction materials has obviously broken through the original concept, not to mention that asbestos is being Gradually replaced by new fiber materials, and in addition to mineral friction-increasing materials and lubricating materials used to adjust the friction coefficient and reduce the wear rate, there are also numerous ...
