Developments of composite joining techniques are explored in this paper. It mainly discusses princi-ples about the composite connection techniques,such as traditional mechanical joint,adhesive joint,stitched joint,Z-pined joint,combined joint and cold rolling riveting. Meanwhile,related factors which influence the per-formances of joint are introduced and the advantages,disadvantages and applicability of various joints are com-pared. The results show that mechanical joint is mature and most widely used. Combined joint is the expansion of mechanical joint,with stitched joint and Z-pined joint often used as auxiliary connection,adhesive joint be-coming mature gradually. Cold rolling riveting has not been researched fully,so it has broad application pros-pect in composite joint process.
