ABSTRACT:
A co-pyrolysis process is disclosed for forming carbonized composite bodies in which co-pyrolysis of organic fibrous and matrix components is effected during initial pyrolysis. Improved interfacial bonding of composite bodies is achieved by combining fibrous precursors, or reinforcements with a controlled pre-shrink state, with an appropriate matrix to insure shrinkage matching during processing. Processing involves the heat treatment of an organic fibrous component, impregnation of the heat treated fibrous component with a resinous binder, forming a layup of the resin impregnated fibrous component, subjecting the layup to molding and curing cycles to form a laminate, pyrolysis of the laminate, and post-pyrolysis heat treatment of the pyrolized laminate.
