Abstract: A three-dimensional braid includes a plurality of first plaits adjacent one another oriented in a first direction and a plurality of second plaits adjacent one another oriented in a transverse second direction intertwined forming a braid with each first plait intersecting each of the plurality of second plaits in succession. Each first plait includes a first group of tows and a second group of tows, each of the tows in the first group of tows corresponding to one of the tows in the second group of tows in pairs of first plait tows. Each second plait includes a plurality of tows. For each first plait, one of the first plait pairs crosses over a subset of second plait tows at each intersection of the first plait and successive second plaits forming a series of braid points along the first plait.

Abstract: A braiding path generating method includes the following steps. Firstly, a mandrel model is received. Then, an outer diameter of the mandrel model is obtained. Then, a target braiding angle is obtained according to a target coverage rate and the outer diameter of the mandrel model. Then, a braiding simulation path is generated according to the target braiding angle.

Abstract: Systems and methods for forming a tubular braid are disclosed herein. A braiding system configured in accordance with embodiments of the present technology can include, for example, an upper drive unit, a lower drive unit, a mandrel coaxial with the upper and lower drive units, and a plurality of tubes extending between the upper drive unit and the lower drive unit. Each tube can be configured to receive individual filaments for forming the tubular braid, and the upper drive unit and the lower drive unit can act against the tubes in synchronization to cross the filaments over and under one another to form the tubular braid on the mandrel.

Abstract: Methods of braiding using a braiding mechanism are described. The braiding machine includes first and second annular members, the second annular member being concentric with the first annular member. A mandrel extends perpendicularly to and intersects a horizontal plane defined by a substantially circular region of the second annular member substantially at the center of the circular region. Each of the annular members has a plurality of tubular guide wires slideably mounted thereon and a plurality of wires extend from the mandrel through each of the tubular wire guides. The first annular member rotates circumferentially relative to the second annular member. The first plurality of tubular wire guides slides radially inward to align with the second annular member, and the second plurality of tubular wire guides slides radially outward so as to align with the first annular member.

Abstract: Methods of braiding using a braiding mechanism are described. The braiding mechanism includes a circular array of filament engagement elements, a mandrel extending from the center of the circular array, a plurality of actuators disposed operably about the circular array, and a rotating mechanism adapted to rotate one or more filaments. The circular array of filament engagement elements and the plurality of actuators are configured to move relative to one another. The plurality of filaments are loaded onto the mandrel and extend radially toward and contact the circumferential edge of the circular array of filament engagement elements. The plurality of actuators are operated to engage a first subset of the plurality of filaments and move the engaged filaments in a generally radial direction to a position beyond the circumferential edge of the circular array. The rotating mechanism is operated to move the engaged filaments about the mandrel axis.
