Zusammenfassung:	The utility model relates to a composite internal thread which comprises a resin-rich layer, a reinforcing fiber unidirectional cloth layer, a hoop winding fiber layer and a helical winding fiber layer. The resin-rich layer is arranged on the surface of a mould thread, the fiber direction of the reinforcing fiber unidirectional cloth layer is the same as the axial direction of a mould core on the resin-rich layer, the fiber direction of the hoop winding fiber layer is arranged outside the reinforcing fiber unidirectional cloth layer and is locked in a tooth socket of the mould thread, and the fiber direction of the helical winding fiber layer is arranged on the hoop winding fiber layer. The composite internal thread employs a method of combining the reinforcing fiber unidirectional cloth layer and the hoop winding fiber layer to shape the composite internal thread, which can increase connecting strength, and reinforced fiber can be reasonably distributed along bearing direction in thread tooth part to increas
