Woven resin brake band Working Principle and Performance Characteristics
Friction Mechanism
During braking, the brake band generates friction with the brake disc through the rough structure on the fiber surface, converting kinetic energy into thermal energy. The resin forms a stable friction film at high temperatures, ensuring that the friction coefficient (0.32-0.65) remains stable within different temperature ranges (100-200℃) and avoiding the "thermal fade" phenomenon. For example, at 150℃, the friction coefficient is 0.35-0.65, and the wear rate is ≤0.76×10⁻⁷ cm³/N・m, showing excellent wear resistance.
Heat Dissipation Characteristics
The resin material itself has good thermal stability, and the porosity of the braided structure helps in heat diffusion. Some designs control heat to concentrate on the surface of the brake disc, reducing conduction to the internal structure, thereby prolonging the service life of the brake band.
Mechanical Properties
The tensile strength can reach 2-3 times that of conventional materials, and it can withstand static pressure loads up to 4.0MPa. At the same time, the braided structure endows it with excellent flexibility, which can adapt to the installation of brake components with complex shapes.
