Adhesion of continuously manufactured fusion bonded multi-material structures consisting of steel and carbon fibre reinforced Polyamide 6

Hence, the present work focuses on the one hand on the evaluation of the adhesion between steel and CFR-TP dependent on various steel as well as CFR-TP temperatures within continuous manufacturing processes. On the other hand, effects of different surface conditions of both materials, due to surface pre-treatments of steel and CFR-TP, on the adhesion are examined. The continuously manufactured specimens are destructively tested by roller peel testing. In addition, evaluation of fracture patterns was carried out for the destructively tested hybrid joints. The examinations show the improvement of adhesion with increasing steel as well as CFR-TP temperature. Furthermore, additional pre-treatment results in an improved adhesion.
