Friction lining and wear-resistant part
View Patent ↗A wear-resistant and high temperature-resistant friction lining, in particular for a transport roller. The lining has a wear-resistant friction component embedded in a matrix and an additional component. The additional component is configured such that it is converted when exceeding a limit temperature while absorbing energy. Due to the endothermic reaction, a cooling effect takes place, which protects the friction lining. In particular, a so-called PBO fiber is used as the friction component.
1. A friction lining, comprising:
a matrix having a wear-resistant friction component embedded in the matrix and the matrix having an additional component,
wherein the additional component absorbs thermal energy from external surroundings, cooling the friction lining, when a temperature limit is exceeded, wherein the friction component is a wear-resistant fiber coated by synthetic resin.
2. The friction lining of claim 1 , wherein the additional component undergoes an endothermic chemical reaction when the temperature limit is exceeded.
3. The friction lining of claim 1 , wherein the additional component is a hydroxide.
4. The friction lining of claim 1 , wherein the additional component is aluminum hydroxide and/or magnesium hydroxide.
5. The friction lining of claim 1 , wherein the matrix is a polymer matrix.
6. The friction lining of claim 5 , wherein the matrix is a thermosetting synthetic resin.
7. The friction lining of claim 1 , wherein the fiber is a PBO fiber.
8. The friction lining of claim 1 , wherein the friction lining is formed by winding one or more fibers.
9. A wear-resistant part, comprising:
a friction lining having a matrix having a wear-resistant friction component embedded in the matrix and the matrix having an additional component,
wherein the additional component absorbs thermal energy from external surroundings, cooling the friction lining, when a temperature limit is exceeded,
wherein the friction component is a wear-resistant fiber coated by synthetic resin.
