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.

A method for the manufacture of a carbon fiber-reinforced ceramic brake or clutch disc for a motorized land vehicle, which method comprises preparing a carbon fiber preform having dimensions which substantially correspond to those of the brake or clutch disc, densifying the preform with carbon in a single stage chemical vapour infiltration process, and siliconizing the densified preform by reaction with molten silicon.
A carbon fiber-reinforced ceramic brake or clutch disc for a motorised land vehicle, wherein the brake or clutch disc consists essentially of a network of reinforcing carbon fibers which have an average fiber length of at least 50 mm and which fibers are substantially completely encapsulated within a siliconised matrix of carbon in isotropic, rough laminar or smooth laminar form.
