    Patent Number:
    US 7922845 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…

    Patent Number:
    US 8178212 B2
    Description:

    Method for chemical bonding of fiberglass fibers to steel surfaces to prepare the steel for bonding with carbon composite material. This fiber-bonding step greatly increases the strength of the subsequent metal-composite bond. The fiberglass fibers which are chemically bonded to the steel provide a high surface area interface to entangle with carbon fibers in the composite component, and thereby inhibit crack formation on the boundary surface between the steel and composite components when th…

    Patent Number:
    US 7588179 B2
    Description:

    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 par…
