Friction material composition for brake pads with reduced storage time
A recently granted patent (Publication Number: US11982330B2) discloses a novel friction material composition for brake pads. The composition includes a multicomponent brake-pad compound and a binder composition based on a hydraulic binder. The hydraulic binder consists of common cement clinker primarily composed of calcium silicates, with additional components such as Al2O3, Fe2O3, MgO, and K2O. The binder composition is further enhanced with an activator and materials with pozzolanic and latent hydraulic activity, all of which contribute to the hardening of the composition through hydration reaction with water.
Moreover, the patent details specific quantities and types of components within the friction material composition, including the presence of type I Portland cement clinker, potassium silicate, potassium hydroxide, slag, and water in the binder composition. The multicomponent brake-pad compound comprises various elements such as metal oxides, steel fibers, aramid fibers, graphite, and metal powders. The patent also covers the use of this composition for brake pads and other industrial applications, highlighting its potential for enhancing braking performance and durability.
