Induction Heated Joining of Aluminum and Carbon Fiber Reinforced Nylon 66

Joining different material types, like metal and thermoplastic fiber reinforced polymer composites (TP-FRPC), offers a large potential for innovative light weight applications. This kind of bonding depends on mechanical, physical, and chemical interactions and is, therefore influenced by joining partner surface treatments. This study describes adhesion models and the effect of surface treatments of AlMg3-CF/PA66-joints. Joining by means of induction heating is an appropriate joining technology for the bonding of metal/TP-FRPC as it is utilized by a rapid heat generation. The characterization of the bonding mechanisms and the influence of the surface treatments are presented by single-lap joints and by microscopic analyses.
