Towards an Explicit Computation of Wear in Brake Materials 2009-01-3048
Although the aspect of wear is generally of high importance in the development of brake materials, a prediction of the wear characteristics, the wear distribution and the wear rate is nearly impossible up to date. This problem has several reasons. Taking a look into the interface dynamics between disc and pad, the growth and destruction of hard and thin structures, so-called “patches” can be found. These patches protect the softer pad ingredients from wear, so wear is not homogeneously distributed in the interface. Thus for the comprehension of the wear-determining parameters this process has to be understood. This paper dedicates to this question and identifies some material-design criteria with respect to wear rates.
