A specially designed test rig is used to determine the compressibility of brake pads. With this test rig, the cold compressibility can be determined according to ISO 6310. A batch of 32 brake pads is examined. For each brake lining, not only is the K6 value determined, but also the complete force-displacement curve recorded.

    Furthermore, a chamber furnace is to be used to pre-load the brake pads thermally. Here, a case of abuse is shown in which the brake lining is exposed to high temperatures. The cold compressibility is then determined here again.

    Another investigation includes the influence of the age of the brake pads on the compressibility. A chamber furnace is used for this in order to reproduce artificial aging of the brake linings. The knowledge gained is particularly relevant for the development of lifelong brakes.

    With the help of the force-displacement curves obtained, an attempt is then made to reproduce the non-linear material behavior in an FEM system as well as possible. Existing material models are used for this and parameterized accordingly. Finally, the material models are compared and their suitability assessed.
