Integrative manufacturing of thermoset injection molding components with continuous fiber-reinforcement
A new process for the manufacturing of thermoset injection molding components with local continuous fiber-reinforcement in one shot has been developed. “Dry” textiles or continuous fibers are inserted into the cavity of an injection mold. Subsequently, the continuous fibers are impregnated and embedded into a short-fiber-reinforced thermoset molding compound by the following injection molding process. In this paper, the technical feasibility of the process is proven by the analyses of the wettability and impregnability of dry carbon-rovings depending on the mold temperature. Furthermore, mechanical tests show that by this new process the integration of continuous fibers into injection molded components improves the mechanical properties if they are impregnated completely.
