抄録
This study was performed to investigate the joining possibilities, strengths (loads,) and mechanisms of the joint between 3 mm thick CFRP (PA6) and 0.7 mm thick zinc-coated steel or 2 mm thick amorphous polyamide (PA) plastic using a continuous wave (cw) diode laser with a line-shaped beam. The results revealed that strong lap joints with the tensile shear load of 3300 N between CFRP and zinc-coated steel could be produced, and many bubbles of sub-millimeter sizes inside the wide shallow melted zone of CFRP near the joint interface were formed. Also, the joint was tightly bonded on atomic or molecular sized levels between the melted plastic and nanometer thick zinc oxide film on the surface of zinc-coated steel. On the other hand, in the case of laser joining of CFRP to amorphous PA plastic, the PA matrix plastic in the CFRP and the amorphous PA plastic at the joint interface were melted and tightly bonded without gap between two materials, and the amorphous PA plastic of the joints was elongated without fracture.
