Comparison Between Different Investigation Methods of Quasi-Static and Dynamic Brake Pad Behaviour 2003-01-3340

The paper offers an investigation of whether the knowledge of the laws materials will follow and of the parameters for the materials can be obtained from integral testing, i.e. the testing of complete brake pads. Dynamic tests were designed for the purpose, with attention to both the axial and the radial / tangential directions of stress as mechanical properties of brake pads. The tests were run and evaluated on brake pads with a variety of patterns and constructions. The term used throughout this paper to describe these features is the matrix. It was shown that brake pads clearly demonstrate visco-elastic behaviour which is most definitely non-linear, and whose characteristic values for stiffness, damping and internal friction will alter in ratio to the load.
