    摘要： A method involves heating fiber-reinforced semi-finished products of differing wall thickness to a required temperature above the glass transition range or the matrix melting temperature of a plastic matrix of the semi-finished product to be heated. In a first step, the semi-finished product to be heated is heated by thermal conduction to below the glass transition range or the matrix melting temperature. In a further step, the remaining amount of heat for reaching the required temperature above the glass transition range or the matrix melting temperature is introduced by thermal radiation or thermal convection.

    摘要： A system and method for fusing at least two thermoplastic composite components together may include placing faying surfaces of the thermoplastic composite components in contact with each other, placing a separation layer over and against one of the thermoplastic composite components, and placing a multi-layer composite pressure pad over and in contact with the separation layer. The method may also include placing an activated inductor against the multi-layer composite pressure pad for induction welding the two thermoplastic composite components to each other. The thermoplastic composite components may comprise conductive fibers while the multi-layer composite pressure pad may comprise a first layer and a second layer with non-conductive fibers. The first layer may at least partially melt during induction welding of the two thermoplastic composite components while the second layer may remain rigid throughout this welding.

    摘要： Each platform mounted mold assembly for plastic tubing includes a circuit board containing parameters defining elements of the forming, molding, tipping or welding operation to be undertaken on the tubing. A control unit includes an RF generator for providing the RF energy to effect the forming, molding, tipping or welding process, a source of air under pressure to operate the mechanical elements attendant each mold assembly, various sensors and a multiplex unit. In operation, the control unit serially addresses each of the mold assemblies, senses the parameters attendant the mold and applies the appropriate power level of RF energy for a specific duration and temperature while activating the mechanical aspects of the mold assembly. The mold assemblies may be serially activated through a multiplex unit or in a particular sequence that may be operator controlled.
