The effect of using heat treated ulexite and cashew in automotive friction materials

In this experimental study, the use of heat treated ulexite and cashew as a new material in brake pads was investigated. The change of friction coefficient, the temperature of friction surface and amount of wear were examined to assess the performance of these samples. Additionlly, microstructural characterizations of braking pads were carried out using scanning electron microscopy. The results showed that the heat treated samples containing ulexite and cashew have an important effect on friction stability and fade resistance. It can be concluded that heat treated ulexite and cashew can be used as friction materials in the automotive brake pads.
