KraussMaffei (Munich, Germany) will show several technologies, including those for long fiber polyurethane composites manufacturing and for thermoforming of composite sheets. The company will feature large components with excellent, immediately paintable surfaces for trucks and agricultural machines that can be manufactured using the LFI (long fiber injection) process in combination with the R-RIM (reinforced reaction injection molding) process. R-RIM is the only process for polyurethane fiber composite applications where the reinforcement material is contained directly in one component. It features a high degree of automation and, therefore, short cycle times. The low viscosity of the components makes it possible to manufacture large, complex, thin-walled, high-strength parts. These applications reportedly feature high temperature stability and an good impact strength and already have paintable surfaces. At JEC, KraussMaffei is presenting a fender for agricultural machines from Parat.
The FiberForm process developed by KraussMaffei combines the thermoforming of composite sheets and injection molding in one process. The strength level of fiber-reinforced plastic components is increased through this procedure. The fully automated process enables short cycle times of less than 60 seconds and production processes that are ready for large series. To date, FiberForm has been predominately used in the automotive industry. At JEC, KraussMaffei is presenting infotainment holders developed jointly for Audi with partners Audi, Lanxess and Christian Karl Siebenwurst.
Also featured will be a multi-function stringer in the new Kingpin touring ski binding from Völkl. The basic body is made up of composite sheet, which is molded with a fiber-reinforced plastic and provided with multiple function elements. On a small, narrow surface, the multi-function stringer contains three highly loaded function elements, all made from fiberglass-reinforced polyamide.
