Three-dimensional braiding ribbed tube process and ribbed tube

Abstract

The invention discloses a three-dimensional braiding ribbed tube process and a ribbed tube. The process is completed on a three-dimensional braiding machine. The three-dimensional braiding machine comprises yarn carriers, wherein the plurality of yarn carriers corresponding to a plurality of main body braiding yarns are distributed on the circumferences of concentric circles with different diameters, and are continuously distributed on the circumferences; a part of the plurality of yarn carriers corresponding to a plurality of rib braiding yarns are distributed on the same circumferences as the main body braiding yarns, and the other part of yarn carriers are distributed in the innermost / outermost ring circumferences of the main body braiding yarns and are arranged concentrically on the circumference with the innermost / outermost ring circumferences; and the yarn carriers move radially and circumferentially to drive the main body braiding yarns and the rib braiding yarns to be knitted for forming the ribbed tube which comprises reinforcing ribs axially arranged on the outer / inner circumferential side walls. The ribbed tube which comprises reinforcing ribs axially arranged on the outer / inner circumferential side walls is formed through the radial and circumferential movement of the main body braiding yarns and the rib braiding yarns; the knitting technology is simple, and easilyrealizes the continuous production; and the obtained ribbed tube has a good mechanical property.

Description

technical field [0001] The invention belongs to the field of braiding technology, and in particular relates to a three-dimensional braiding reinforced pipe technology and the reinforced pipe. Background technique [0002] The biggest feature of the three-dimensional braided fabric is that it has no layer structure and can be formed in one piece. Therefore, the three-dimensional braided composite material is a complete integral structure with high specific strength and specific modulus. It has excellent mechanical properties and can be widely used in aerospace, Aviation, medical and other fields. At present, researchers have done a lot of work on three-dimensional braided composite pipes, but most of the research has focused on variable-section pipes. The weaving process of the variable cross-section pipe is to weave the variable cross-section pipe by increasing or reducing the yarn during the weaving process. The weaving process is complicated, the weaving process is diffic...
