title = "MANUFACTURE OF STEEL-CF/PA6 HYBRIDS IN A LASER TAPE PLACEMENT PROCESS: EFFECT OF SUBSTRATE SURFACE TEXTURE ON FIRST PLY PLACEMENT AND COMPRESSION SHEAR STRENGTH",
abstract = "This paper investigates the effect of steel substrate surface texture on the first ply placement and compression shear strength of metal-composite (carbon fibre/polyamide 6) hybrids manufactured in a laser-assisted automated tape placement (ATP) process. Texturing of the steel surface, using an ultrashort-pulsed laser, increased laser absorptance during ATP by 23\%. Additionally, the scatter pattern changes from predominantly specular reflection for the pickled surface to a broad scatter for the grit blasted and the laser textured surface. The highest bond-line shear strength was obtained at a substrate temperature of 330°C for the grit blasted and laser textures surface due to a better flow of matrix in the surface asperities resulting in mechanical interlocking. High absorbing surface textures reduce the laser power required for the first ply placement by 25\%.",
