IMPROVEMENTS IN OR RELATING TO BRAKE AND CLUTCH DISCS

摘要

Carbon fibre-reinforced ceramic brake and clutch discs are manufactured by siliconising incompletely densified carbon-carbon fibre preforms produced by only a single liquid infiltration step. Such use of only a single step to densify the preform substantially reduces processing times and costs whilst yielding highly effective siliconised end products, which may optionally then be subjected to a further carbon impregnation step, e.g. by a single chemical vapour or liquid infiltration step, to optimise their structural and frictional properties, particularly in terms of stability at high temperatures.
