    摘要： Production of pore-free carbon/carbon-silicon carbide composite materials with mechanical properties making them suitable for use in such applications as the production of aircraft landing system brake components including brake discs. The method includes: providing a porous carbon-carbon composite preform; surrounding the porous carbon-carbon composite preform with silicon powder to form an intermediate construct; applying a uniaxial load to the construct; applying direct electrical current to an assembly containing the loaded construct of porous carbon-carbon preform surrounded by silicon powder, thereby melting the silicon powder and infiltrating the pores of the carbon-carbon preform with liquid silicon; and initiating a combustion-type reaction between the silicon and carbon in the preform, thereby forming silicon carbide in the preform.

    摘要： Resin-impregnated carbon fiber composites containing metal inserts. Carbon fibers or a carbon fiber preform are bonded to a metal structural member. Once the carbon fiber-metal bond is established, the fiber-metal assembly or hybrid preform is impregnated with resin, to form an article in which bonding between the metal structural member and the composite remainder of the article is greatly enhanced. In a process embodiment, a metal insert, e.g. a steel insert, is provided in contact with particulate carbide-forming metal, e.g. titanium, and with carbon fiber segments. Then an electric current is passed through the carbide-forming metal particles and carbon fibers to heat them to a temperature above the melting point of the carbide-forming metal. This initiates an exothermic reaction, which forms liquid phase metal carbide. Subsequently the liquid phase metal carbide is cooled and solidified, thereby bonding the carbon fiber segments to the metal insert.

    摘要： A method for synthesis of biomedical alloys has been developed based on combustion phenomena. This low pressure combustion synthesis (LPCS) technique may be used for production of Co-based and other metal-based alloys, which cover the entire range of orthopaedic implants, including total hip and knee replacements, as well as hone screws, plates, and wires. A unique aspect of the method is that combustion synthesis under low ambient gas pressure allows one to produce pore-free (>99% theoretical density) alloys with high purity and precise chemical and phase compositions.

    摘要： Method of joining carbon-carbon composite pieces together, e.g. in the refurbishment of aircraft brake discs. The method includes the steps of: providing a first carbon-carbon composite piece and a second carbon-carbon composite piece, wherein the second carbon-carbon composite piece has a surface that is complementary to a surface of said first carbon-carbon composite piece; providing a layer of a mixture of titanium powder and carbon powder on the first complementary mating surface; arranging the second carbon-carbon composite piece on the powder layer such that the second complementary mating surface is matched to the first complementary mating surface, thereby forming a construct of the first carbon-carbon composite piece, the powder layer, and the second carbon-carbon composite piece; placing the construct into a press and applying pressure to the construct to press together the two pieces joined at their complementary surfaces; and applying an electrical current to the powder in the construct to initiate an oxidation-reduction reaction, thereby bonding the carbon-carbon composite pieces together.
