Abstract
Methods of producing a fiber reinforced polymer matrix composite and a composite thermal protection system formed from the same. The method includes forming a polymerized fiber reinforced composite which including a cured thermoset polymer matrix and at least one reinforcement material. The method further includes treating at least a portion of a first face of the polymerized fiber reinforced composite with electromagnetic radiation to raise the temperature of the portion of the first face to at least 800° C. to produce a surface layer of graphitized carbon and a bulk polymerized fiber reinforced composite representing the untreated polymerized fiber reinforced composite. Further, the surface layer of graphitized carbon has an electrical conductivity of 0.25 S mto 2.5 S mwhere the electrical conductivity and a thermal conductivity are both greater than those of the bulk polymerized reinforced composite.
