Abstract：The heterogeneous structures between polymers/polymer matrix composites and aluminum alloys can fulfill the desired requirements in structural properties and lightweight design. Friction stir welding (FSW) is a solid state welding technique characterized by low temperature and severe plastic deformation, which cannot be influenced by crystal structures, physical and chemical properties FSW can realize high-quality joining between polymers and aluminum alloys. Aiming at welding parameter optimization, joint formation, defect types and causes, strength improvement and so on, the current progress of FSW between polymers and aluminum alloys was reviewed. Meanwhile the future outlooks and engineering application were further prospected.
