Abstract

Classical wear and friction experiments on a Pin on Disc - with composite disc - yield the formation of a thin film at the composite wear track, as a result of particles, falling from the edges of the wear track, being pressed against and later on over the composite surface, depending on the normal force and the underlying composite structure. This thin film deforms continuously, resulting in larger and darker wear particles at the edges of the wear track. Another mechanism for the building up of this thin film is that due to the shear forces in the film under the pin top that the underlying structure ‘wears’ and results in different characteristic wear mechanisms. This thin film yields a reduction of the frictional force with almost 20%. After the ‘removal’ of the film as a result of the structure the friction force reaches is old level. Related to the production method, the results of the fibre orientation on the friction force can be shown. Perpendicular fibre orientation yields higher frictional force, parallel results in a lower friction force.
