- Patent Number:
- US 8383197 B2
- Description:
A metal powder is applied to the surface of the area of a carbon-carbon composite brake disc to be protected against migration of antioxidant. The metal powder may be titanium powder or tungsten powder. A chemical reaction between the metal powder and carbon is then initiated by heating the powder-coated brake to the ignition temperature via application of electric current (Joule preheating) or by heating it in a furnace. Upon combustion, the metal particles react with carbon in the composite…

- Titanium carbide or tungsten carbide with combustion synthesis to block porosity in C-C brake discs for antioxidation protection
- Description
- A metal powder is applied to the surface of the area of a carbon-carbon composite brake disc to be protected against migration of antioxidant. The metal powder may be titanium powder or tungsten powder. A chemical reaction between the metal powder and carbon is then initiated by heating the powder-coated brake to the ignition temperature via application of electric current (Joule preheating) or by heating it in a furnace. Upon combustion, the metal particles react with carbon in the composite, forming liquid carbide that flows into pores of the composite brake disc to be protected.

- Patent Number:
- US 8448685 B2
- Description:
An apparatus for bonding a first carbon composite to a second carbon composite through a reactant layer includes a housing, and a pair of conductive press plates electrically isolated from the housing. The press plates are adapted to position the two parts to be bonded with a reactant layer therebetween. The press plates are subjected to an electrical potential and a clamping force, sufficient to initiate a combustion reaction that creates a molten ceramic to bond together the carbon-carbon c…

- Bonding of carbon-carbon composites using titanium carbide
- Description
- 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.
