| Abstract | This contribution is about the experimental and numerical investigation of cfrp thermoplast interface joint strength. In tensile tests the joint strength of lap-shear-joints with cfrp thermoplast hybrid specimens with different surface structures are investigated. Comparing to a smooth reference, pin structures show the highest increase in joint strength up to 500 %. In FE simulation the optimal geometry for pins is determined to an ellipse. Further, the strengthening effect of pins towards the displacement reduction in joint interface is shown. Here, elliptic pins which are stretched in load direction are found to be most feasible in this application. Finally, three different visualisation techniques are introduced to determine pin’s position on interface surfaces. |
