Direct joining of plastic to copper by friction lap joining

Abstract

Pure copper (Cu) were joined to polyamide 6 (PA6) directly by friction lap joining (FLJ) at the joining speed of 200-1600 mm/min with a constant rotation rate of 1000 rpm. As the joining speed increased, the tensile shear force increased first, and decreased thereafter, and the maximum tensile shear force at 800 mm/min could approach to 1 kN. The effect of the joining area, the strength of the melting plastic matrix, and the bubbles on the tensile shear force was discussed.
