Abstract: A method for making a high temperature composite, which is a carbon carbon composite, carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or a carbon silica composite, including: a) providing a precursor part including a resin comprising a poly(aryl ether ketone) (PAEK) and at least one reinforcing material, wherein the resin has a degree of crystallinity of 10% or more; b) pyrolyzing the precursor part to a pyrolyzed part; c) infusing a liquid second resin into the pyrolyzed part to make an infused part; and d) pyrolyzing the infused part to make the carbon carbon composite carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or the carbon silica composite, optionally repeating steps c. through d. Also, a carbon carbon composite, carbon fiber reinforced ceramic matrix composite, ceramic fiber reinforced ceramic matrix composite, or carbon silica composite made by the method.
