Abstract
Method of joining a carbon-carbon composite piecetogether with a metal insert, e.g. in the manufacture of aircraft brake discs. The method includes the steps of: providing a carbon-carbon composite pieceand a metal insert, wherein the metal inserthas a surface that is complementary to a surface of said carbon-carbon composite piece; providing a layer of a mixture of titanium powder and carbon powder on the first complementary mating surface; arranging the powder layer such that a second complementary mating surface is matched to the complementary mating surface, thereby forming a construct of the carbon-carbon composite piece, the powder layer, and the metal insert; placing the construct into a press and applying pressure to the construct to press together the carbon-carbon composite piece and the metal insert joined at their complementary surfaces; and applying an electrical current to the powder in the construct to initiate a metal-carbon reaction, thereby bonding the carbon-carbon composite piecetogether the metal insert. The titanium powder particles may be from 25 to 100 microns in diameter, and the carbon powder (e.g., graphite particles) may be 0.1 to 1 microns in diameter.
