Thermal Analysis of Friction Materials
A polymer-bound friction material such as an automotive brake lining is a complex system (Figure 1) consisting of (a) an organic resin binder, such as a phenolic or a modified phenolic; (b) asbestos fibre, which is a reinforcing agent; (c) friction property modifiers. A typical photomicrograph (Figure 2) shows the physical appearance of the ingredients in the bulk of the lining. Also shown is the layer affected by heat generated at the lining-drum interface.
