Abstract: Carbon fibre-reinforced ceramic brake and clutch discs are manufactured by siliconising incompletely densified carbon-carbon fibre preforms produced by only a single chemical vapour infiltration step and then subjecting the siliconsised densified preform to a carbon impregnation step, e.g. by chemical vapour or liquid infiltration. The method substantially reduces processing times and costs compared to conventional chemical vapour infiltration processes, whilst yielding highly effective end products with optimised structural and frictional properties, particularly in terms of stability at high temperatures.

Abstract: Highly effective carbon fibre-reinforced ceramic automotive brake and clutch discs are manufactured by siliconising incompletely densified carbon-carbon fibre preforms produced by a single stage and relatively short duration (e.g. 7-14 day) chemical vapour infiltration process.
