Embodiment Construction
[0022] An example of a three-dimensional braided tube based on space group P4 Figure 1-7 As shown: the three-dimensional braided tube 10 includes five braided layers formed by single-layer representative volume units 11, and each representative volume unit 11 is composed of two circumferential yarns formed by the circumferential movement of the corresponding circumferential yarn carrier. The yarn section 12 and two radial yarn sections 13 formed by the radial movement of the corresponding radial yarn carrier, any one yarn section in the same representative volume unit 11 is interspersed between two adjacent yarns between sections. Each representative volume unit is arranged into a circular tube structure in which each yarn node is connected in corresponding order in the circumferential direction and in corresponding order in the axial direction.
[0023] Due to multiple braided layers, the representative volume units at the inner edge position, the representative volume unit...

The invention relates to a three-dimensional braided tube, and a three-dimensional braiding machine and a braiding technology for manufacturing the three-dimensional braided tube. The three-dimensional braided tube comprises a plurality of representative volume elements, wherein each representative volume element consists of two circumferential yarn knots and two radial yarn knots, the circumferential yarn knots are formed by the circumferential movement of a corresponding circumferential yarn carrying device, and the radial yarn knots are formed by the radial movement of a corresponding radial yarn carrying device; any yarn in any one representative volume element is penetrated between two adjacent yarn knots; the representative volume elements are arranged to form a circular tube structure of which the yarn knots are connected in a corresponding sequence in a circumferential direction and are connected in a corresponding sequence in an axial direction. The invention provides the three-dimensional braided tube based on a space group P4, and the three-dimensional braiding machine and the braiding technology for manufacturing the three-dimensional braided tube.
Description
technical field [0001] The invention relates to a three-dimensional braided tube based on space group P4 in the field of three-dimensional braided tubes, a three-dimensional braided machine and a braiding process for making the three-dimensional braided tube. Background technique [0002] In recent years, three-dimensional braided composite materials have been widely used as a new type of engineering material. Because of their advantages of complete structure, one-time molding, and time-saving and labor-saving, this braided fabric is widely used in various fields and has been approved by the Institute of Weaving Technology. Considerable attention. [0003] In order to obtain braided materials with more stable geometric structure and better mechanical properties, people have been making new attempts on braided structures from space group P3 to space group P4. Chinese patent CN105063885A discloses a "three-dimensional braided material based on space group P4 symmetry", which ...
