Reinforcing fibers for friction materials
The fiber reinforced material constitutes the main body of the friction material, which endows the friction product with a certain friction performance and sufficient mechanical strength, so that it can withstand the load force of the grinding and riveting processing of the friction plate during the production process, as well as the braking and The impact force, shear force, pressure, and high-speed rotation of the clutch generated by the transmission can avoid damage and rupture.
According to the actual working conditions of the friction plate, the corresponding mechanical strength requirements are put forward for the friction plate, such as impact strength, bending strength, compressive strength, shear strength, rotational failure strength, etc. In order to meet these strength requirements , It is necessary to select suitable fiber varieties. When selecting, the strength performance of the fiber is a very important selection principle, that is, not only a good reinforcement effect, but also a cost price that can be accepted by the market, which is particularly important for friction materials. , because only friction products with good technical and economic comprehensive performance can have strong market competitiveness.
