FUP - A New Method of Producing Composite Moldings from Thermoplastics and Thermosets.

Under the designation FUP (German abbreviation of ″Fuegeumformen mit Polyreaction″ ) a new developed plastics processing technique for the production of composite moldings is introduced. Its use in trails on an injection molding machine is reported. In the new process composite formation and shaping by casting and injection molding or extrusion take place in a single operation and a single tool. The report deals with the investigation into the principal feasibility of the technique and the assessment of component quality. It is the objective of current and further investigations to test the behavior of the composite structures under various mechanical, thermal and climatic stresses. Moreover, further work on the use of the technique in extrusion is intended. Finally, attempts are envisaged to elucidate the influence which the special chemistry of the reactive phase exerts in particular on the combinations with polyolefins.
