Methods of producing carbon-carbon parts having filamentized composite fiber substrates
First Claim
Patent Images
1. A method for producing a carbon-carbon part comprising the steps of:
- producing a filamentized composite substrate without a batch carbonization step, the substrate comprising a plurality of discontinuous, randomly oriented, carbonized filamentized fibers and a binder that binds said filamentized fibers together to form the filamentized composite substrate; and
depositing carbon atoms by chemical vapor deposition at a predetermined temperature onto the filaments such that said carbon atoms replace said binder within said substrate and said carbon atoms densify said substrate to form a carbon-carbon part.

Abstract
A method of producing a carbon-carbon part having a filamentized composite fiber substrate is provided. A substrate having a plurality of discontinuous filamentized fibers and a binder that binds said filaments together to form a composite substrate is provided, and carbon atoms are deposited onto the filaments at a predetermined temperature so that the binder is removed completely from the filaments and replaced with carbon atoms to from a dense carbon-carbon part.
