Disclosed is a method for manufacturing a composite joint, comprising the following steps: determining a high strength joint corresponding region (S1); manufacturing a first adhesive layer (113) on one face of a first rigid piece (11), then cutting a slot (111) as a joint rotating position and cutting away the high strength joint corresponding region to form a first notch (112) (S2); manufacturing a second adhesive layer (123) on one face of a second rigid piece (12), then cutting out a slot (121) as a joint rotating position (S3); manufacturing a third adhesive layer (131) on one face of a third rigid piece, and cutting out a first filling piece (13) on the third rigid piece (S4); aligning and adhering the first rigid piece (11) and the second rigid piece (12) on two faces of a piece of flexible fabric (15) (S6); placing the first filling piece (13) in the first notch (112) (S7); and cutting out a joint outer frame (16) to obtain a composite joint (10) (S8). The method for manufacturing a composite joint can merely use a high strength material for the third rigid piece or coat same with a high strength adhesive, thereby ensuring the strength of the manufactured composite joint, while reducing costs.
