Composites produced from two or more different materials with different physical and chemical properties often allow for tailoring mechanical and other characteristics of the resulting multi-material system. Fiber-reinforced plastic composites have usually high strength and elasticity due to a combination of the tough but weak plastic matrix with the strong and stiff reinforcing fibers, filaments or textile layers.
Combinations of textile materials with 3D printed polymers, however, result in different mechanical properties of the composites. While the tensile strength of the multi-material system is increased compared to the pure 3D printed material, the elasticity of the polymer layer can be retained to a certain degree, since the textile material is not completely immersed in the polymer. Instead an interface layer is built in which both materials interpenetrate to a certain degree.
The poster will give an overview of the parameters affecting the interface layer. The influence of this interface layer on possible delamination and mechanical properties of the developed composites will be depicted, resulting in the possibility to tailor the desired strength and elasticity of polymer-textile composites.
