Abstract
A lining element includes at least three layers and is configured to be mounted to a structure exposed to wear. The lining element has a wear-impeding polymer layer, an energy-absorbing polymer layer and a reinforcing polymer layer. The reinforcing layer is located adjacent the structure exposed to wear, whereas the energy-absorbing layer is located between the reinforcing layer and the wear-impeding layer. The wear-impeding layer is located on top of the energy-absorbing layer.
