Description

As shown in FIG. 2, in one embodiment, four braided bobbins 210, 220, 230, 240 are prepared in a similar manner, after which they preferably move in a clockwise direction with the bobbins 210, 220 The bobbins 230, 240 are loaded into the maypole braider in a balanced quarter carrier configuration so that they move counterclockwise in a serpentine motion. The braider then forms a helically intertwined yarn structure with minimal twist and small braid angle, preferably without the use of a core or mandrel, with mechanically constrained functional components. Any number of such braided bobbins may be used, and the braided bobbins may contain the same or different multi-component fiber bundles. One or more other optional bobbins containing only structural material are optionally additionally loaded into the braiding machine as needed to braid the yarn in the desired yarn size and construction. good too. This configuration produces a biaxial or two dimensional (2D) braid, although embodiments of the invention can be produced on a triaxial or three dimensional (3D) braiding machine.
