DEVICE FOR PRODUCING REINFORCED AND TOUGHENED COMPOSITE PIPE
The present invention relates to the technical field of composite pipes, and provides a device for producing a reinforced and toughened composite pipe. The present invention solves the problem in the prior art that composite pipes are weak in strength. The device for producing a reinforced and toughened composite pipe comprises an extruder, a forming mold, a core pipe communicated with the extruder, an outer pipe sleeved outside the core pipe, and a winding machine capable of coating the outer peripheral wall of the outer pipe with reinforcing fibers; a forming cavity is formed between a core mold and an outer mold sleeve of the forming mold; an outlet end of the core pipe extends into the forming mold and is communicated with the forming cavity of the forming mold; one end of the outer pipe is connected to the forming mold; and a reinforcing fiber layer on the outer peripheral wall of the outer pipe can penetrate through the forming cavity. A composite pipe produced by the production device has the advantages of high strength and good toughness.
