Abstract: A method for making a carbon carbon, carbon ceramic matrix, or carbon silica composite, comprising melt processing a resin comprising a polyaryletherketone (PAEK) and at least one reinforcing additive to make a precursor part, pyrolyzing the precursor part to make a pyrolyzed part, infusing a liquid second resin into the pyrolyzed part to make an infused part, and pyrolyzing the infused part. Other methods comprise processing aligned reinforcing additives and a resin comprising a PAEK to make an aligned reinforcing additives PAEK, aligned 1-2 dimensional flake material, or aligned 1-2 dimensional platelet material, to create a fabric, prepreg or tape comprising the aligned reinforcing additives and impregnated PAEK. Other methods comprise impregnating continuous fiber tape or fabric with a resin comprising PAEK and at least one reinforcing additive or co-weaving a continuous fiber or fabric with a PAEK fiber comprising PAEK and at least one reinforcing additive.
