Abstract

Abstract In this paper, quasi-isotropic basalt fiber reinforced polyamide PA6 was joined to aluminum sheets using three different joining technologies. The joints were manufactured by means of nut and bolt (NAB) as well as two-piece hollow riveting (TPHR) as current state of the art processes. Furthermore, additional joints were established by the new inductive contact joining (ICJ) technology. The obtained specimens were compared by means of tensile shear tests and by analysis of the fractured surfaces. It was found that the joints produced by ICJ are superior in comparison to joints manufactured by TPHR with regard to joint strength. In addition, during ICJ, the fibers of the polymer material are not damaged and the strength of the base material is maintained. Further optimization potential of the ICJ process was discovered during the investigations, so that potentially higher joint strengths as well as shorter process times can be expected, making the process interesting for future industrial applications.
