Modern brake materials in automotive engineering consist of a soft polymeric matrix with embedded SiO2particles, iron swarfs or similar materials.
For technical brake systems the stress and the temperature may increase until alloying processes between the hard particle and the wear particle flow will occur (some analysis indicates even the possibility of creating ceramic structures).
