Commonly used friction materials for automobile clutch disc include powder metallurgy materials, asbestos-based materials, and paper-based materials. These materials will be discussed in detail below

Powder metallurgy material: high surface temperature, high pressure, high friction coefficient, long service life at high temperature. It is up to them to have different uses for different metals. For example, copper-based powder metallurgy materials are mainly used for wet friction surfaces; iron-based powder metallurgy materials have higher friction coefficient and allowable pressure than copper-based materials, but lower wear resistance, and are mainly used for dry friction surfaces.

Asbestos Substrate: Molded with asbestos, binders, and fillers, consolidated on a steel or iron base plate, low operating temperature.

Paper-based material: It is made of interwoven asbestos, plant fibers, or a mixture of the two, and is bonded with resin after adding filler.

As the friction material of the clutch plate, it must have the following chemical and physical properties to fit the use of the clutch plate. Then this requires that its friction coefficient is large and stable, and the dynamic friction coefficient should be as close as possible to the static friction coefficient; high strength, can withstand impact, not easy to crack and peel at high speed; wear resistance, high-temperature resistance, corrosion resistance, good thermal conductivity, small thermal deformation; Long-term storage of non-stick pans; long service life, easy processing, and low prices are also required.
