| Abstract Scope |
Requirements to reduce fuel consumption and carbon dioxide release in the automobile industry necessitate the use of lightweight structural materials such as magnesium alloys and carbon fiber reinforced polymers (CFRP). Magnesium alloys have the lowest density among all the structural alloys; CFRP possess even higher strength-to-weight ratio comparatively. A mechanically reliable joint between magnesium alloys and CFRP can decrease vehicle weight and boost design flexibility in the automotive industry. However, joining between metals and polymers is challenging due to the large differences in their physical, chemical, and mechanical properties. Friction Stir Interlocking technique was developed to fabricate joints between magnesium and CFRP by introducing pre-machined interlocking features made of magnesium inserts, while minimizing polymer degradation. Design of interlocking parts and welding tools were optimized. In addition, mechanical properties of welded joints were evaluated with different test methods. |
