description	The invention belongs to the field of profile manufacturing, and provides a thermoplastic composite pultrusion and injection molding integrated forming method which comprises the following steps: dividing a preformed section of a multi-cavity complex structural member into a main bearing structure and a secondary bearing and functional structure; multi-axial cloth or unidirectional fibers are adopted for layer laying and pultrusion, and a main bearing structure is obtained; performing injection molding on chopped fibers and thermoplastic resin to form a secondary bearing and functional structure, curing the secondary bearing and functional structure and the main bearing structure into a whole, and performing cooling, traction and cutting to obtain the composite material. According to the performance and function requirements, the preformed section is subjected to structural division, the main bearing structure is subjected to pultrusion, and the inner ribs of the secondary bearing and functional structures ar
