Abstract

Abstract: Fiber reinforced composites have outstanding advantages such as high specific strength, high specific modulus, excellent structural performance and great designability, and are able to achieve components lightweight and integrated structural functional design. These composites have important strategic positions in the fields such as aerospace, transportation, energy, and national defense technology. With the widespread application of fiber reinforced composites in the aerospace and other fields, high-performance joining technology between the composites and lightweight alloys has become one of the important guarantees for the strength and stability of aviation structures. Focusing on the mechanical fastening, adhesive bonding, and welding between composites and the light alloys and composites, this paper reviews the latest research progress in the joining technology of fiber reinforced composites. The technical characteristics of various joining technologies of the composites were comprehensively discussed and analyzed. The advantages and disadvantages of various joining technologies, as well as the improvement ability of joining structure performance, were also summarized and compared. Furthermore, the future development and research trends of various joining technologies are proposed.
