    摘要： A method for welding thermoplastic composite components is provided that includes: providing a first thermoplastic composite component having a first weld region surface; providing a second thermoplastic composite component having a second weld region surface; disposing the first and second weld region surfaces in stationary contact with one another; ultrasonically welding the first and second thermoplastic composite components using a ultrasonic welding device having a sonotrode that linearly reciprocates, the welding including contacting an engagement surface of the first or second thermoplastic composite component with the sonotrode and reciprocating the sonotrode along a travel axis that is parallel to the first and second weld region surfaces until at least one of the first or second thermoplastic material reaches a melt temperature; and then maintaining the first and second weld region surfaces stationary until cooled.

    摘要： The invention relates to an electrically conductive, polymer based material with electrical resistivity having a positive temperature coefficient. The material comprises a matrix of thermosetting polymer having conductive particles in the form of fibers distributed through the polymer. The polymer can be an epoxy resin, polyimide, unsaturated polyester, silicone, polyurethane or phenolic resin, and the fibers can be carbon fibers, carbon fibers coated with metal or metal alloy, graphite fibers, graphite fibers coated with metal or metal alloy, graphite intercalation compound fibers, metal fibers, ceramic fibers, or ceramic fibers coated with a metal or metal alloy.
