The working mechanisms of our mineral fibres
Braking is the result of a surface interaction between brake disc and friction material surfaces like a brake pad. The mechanisms taking place at this contact area are a combination of physical, thermomechanical and chemical phenomenoa. Kinetic energy has to be converted into heat, plastic deformations, chemical reactions and wear debris.
The performance of the brake system is influenced by the formulation of the friction material. A typical friction material consists of 10-20 raw materials. Each raw material has a unique chemistry, size and shape and therefore a unique functionality. Finding the right balance between these functionalities is crucial in the development of friction formulations.
