N2 - This paper investigates the possibility of manufacturing hybrid metal/composite laminates in a laser tape placement process. Unidirectionally reinforced carbon fibre/PA 6 composite tapes were applied to 2.0 mm mild steel substrates. The effect of two surface treatments to the steel substrates were investigated 1) grit blast and 2) application of a 60 μm PA 6 film. The effect of laser bias angle was also studied. The interfacial bond strength of the hybrid laminates was determined by means of lap shear tests following the ASTM D 5868 standard. Direct placement onto steel was unsuccessful due to the high laser reflectivity, however placement onto PA 6 coated substrates was successful due to increased laser absorptance. The lap shear strengths as high as 29.5 MPa were achieved for grit blasted and PA 6 coated substrates. The process was found to have a low sensitivity to laser bias angle.
