Development and analysis of the effect of a 3-dimensional reinforcing frame structure with additive manufacturing from renewable resources on the morphological and mechanical properties of injection molded polymer composites

Project summary

Due to environmental regulations and decreasing amount of raw materials, the mass and load optimization of engineering products are receiving more emphasis. Nowadays, polymer composites are more and more used in engineering applications as load-bearing structures and injection molding is one of the most often used polymer composite processing technologies, due to its high productivity and reproducibility. However, for injection molded composites, a disadvantage is that the orientation of the reinforcing fibers is determined by the flow conditions and also fiber breaking occurs during processing, thus the reinforcing possibilities of the fibers cannot be utilized to the full. In most cases, researchers attempt to solve the problem by optimizing the manufacturing technology. By contrast, we set out to develop a complex solution for the problem, which facilitates better adaptation of the reinforcing fibers and structure in injection molded structures to conditions of use, and results in better structural integrity and load bearing. The overall goal of the project is to create a complex design methodology with which a tailor-made reinforcing structure can be made in injection molded parts as a separate 3D printing step. It makes the production of a composite frame possible with directed mechanical properties within the injection molded product in one step. The reinforcing fibers are oriented previously and they keep their planned orientation during the injection molding process.
