CARBON COMPOSITE BRAKE DISC MANUFACTURE

摘要

A method is provided of making a non-woven fabric sheet for use as a substrate in a carbon-fibre-reinforced carbon composite. Carded staple fibre is placed transversely to continuous filament and needle punched to form a fabric which is superior to an all- continuous-filament fabric in that (a) it has improved infiltration characteristics and (b) staple fibre recovered from off- cut material can be re-cycled.
