Abstract
Results and analysis from investigations into the behaviour of the interfacial layer (Tribolayer)
at the friction interface of a brake friction pair (resin bonded composite friction material
and cast iron rotor) are presented in which the disc/pad interface temperature has been
measured using thermocouple methods. Using a designed experiment approach, the interface
temperature is shown to be affected by factors including the number of braking applications,
the friction coefficient, sliding speed, braking load and friction material. The time-dependent
nature of the Tribo-Iayer formation and the real contact area distribution are shown to be
causes of variation in interface temperatures in friction braking. The work extends the
scientific understanding of interface contact and temperature during friction braking.
