ABSTRACT:
A method for manufacturing carbon-carbon composite bodies consisting essentially exclusively of carbon, of about 20 to about 96 weight percent from carbon fiber, from 0 to about 72 weight percent from a carbonaceous flour, and from about 4 to about 15 weight percent from a carbonized resin, which consists in forming a mat by allowing a mixture of the solid ingredients to settle to equilibrium height by the force of gravity or by centrifugation in a solution of the resin and an appropriate solvent, then pressing the settled solids at up to about 100 psi and removing the excess liquid therefrom. Heating the formed and pressed mat to cure the resin, and then baking and optionally graphitizing the cured mat completes the process.
