Development, Analysis, and Validation of an Economically Efficient Process Chain for a Rigid CFRP Plate Assembly Using Finger Joints

Abstract

For the mechanical engineering sector it is crucial to develop cost efficient process chains to produce CFRP components. CFRP material is usually compared to steel due to its high specific tensile strength and high specific rigidity. Thus, joining techniques known from steel are used to join CFRP parts. In contrast, this study focuses on the elements and production processes known from wooden parts. The wood industry uses connection techniques appropriate for the anisotropic material behavior of CFRP. The finger joint was identified as a suitable connection for CFRP components. It transmits forces by form fit and allows for easy assembly.
