▎ 摘　　要

NOVELTY - Method for making a high temperature composite, which is a carbon carbon composite, a carbon ceramic matrix composite, or a carbon silica composite, involves (a) making a precursor part from a resin comprising a polyaryletherketone (PAEK) and at least one reinforcing additive, (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, the carbon ceramic matrix composite, or the carbon silica composite, and (e) optionally repeating steps (c) through (d) one or more times. USE - The method is used for making a high temperature composite, such as a carbon carbon composite, a carbon ceramic matrix composite, or a carbon silica composite (claimed). ADVANTAGE - The method provides easy processability, and has high char yields and high mechanical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a carbon carbon composite, carbon ceramic matrix composite, or carbon silica composite.
