Polymer-based hybrid structures are gaining a lot of attention as materials for automotive components, but also for everyday products. One type of material, the so-called microfibrillar reinforced composite (MFC), offers great potential for applications under medium loads. This hybrid material consists of polymer fibrils that are embedded in a polymer matrix. Compared to conventional fiber-reinforced composites, MFC offers manufacturing advantages, lower density and excellent recyclability. Since the fiber orientation in the manufacture of molded parts can hardly be controlled with conventional processes such as injection molding, the industrial potential of MFC has not yet been fully exploited. When processing in the FDM process, however, the reinforcing fibrils in the MFC can be perfectly preserved and perfectly aligned in the direction of printing in the components, which enables the highest level of strength and rigidity in this direction. The aim of our current research is the manufacture of MFC using FDM technology and the optimization of processing in order to significantly improve the component properties and material efficiency.
