  • Method of increasing the strength of carbon and graphite members
    Patent number: 4366191
    Abstract: Increasing the strength and improving other properties of porous carbon or graphite bodies by immersing the porous body in a mixture containing 35-70% hardenable resin and 30 to 65% volatile solvent to impregnate pores. The impregnated porous body is heated to 120.degree. to 180.degree. C. to harden the resin. Carbonization of the body is effected by heating in an inert atmosphere at a rate of at least 3 K/hr to 800.degree.-1300.degree. C. Improved strength bodies are obtained with a single impregnation and single carbonizing step.
