A flat broad good is manufactured from a portion of an intermediate braided structure laid into flat broad good form. The portion forming the flat broad good is a stabilized braided biaxial structure.
Abstract:
Various methods (1000, 1100) can be employed to apply a braided product to an irregular core. Application can occur while preserving the integrity of the braided structure. A system (200) can be designed in turn to apply a braided product to an irregular core (212). The system can include a mandrel (206) that prevents distortion of the braid during application. System (200) can additionally include a pinch clamp (210) and cam track assembly (214) that are designed based at least in part on the irregular core (212). Further, a mandrel (100) can be designed to prevent distortion of braiding of a braided structure by maintaining constant length in all directions.
Abstract:
A spacing component comprising a longitudinal axis wherein the structural spacing component may be configured to provide a boundary between a first object and a second object along its longitudinal axis is described. The structural spacing component may further comprise a restrictive layer enclosing an interior region wherein the restrictive layer may comprise a first length along the longitudinal axis and at least one second length transverse to the longitudinal axis. In examples, the restrictive layer may be formed of a plurality of braided strands. Additionally, the restrictive layer may define at least a partially enclosed interior region and may have flexural stiffness to maintain the first length as greater than the second length.
Abstract:
Braided material with multiple braided components formed of continuous tows and connected by one or more intersections are described. Each of the multiple braided components is formed by sets of tows. Each set of tows includes a respective plurality of tows, which are substantially adjacent and parallel to each other at an angle relative to the longitudinal axis of the braided material. Each set of tows is further composed of multiple subsets of tows. The subsets of tows separate at the intersections and combine with different subsets of tows in adjacent components of the multiple braided components.
Abstract:
A braided sleeve with complex geometry, including changes to the geometry along the braided sleeve's longitudinal axis are described. In particular, along a first portion of the braided sleeve's longitudinal axis, multiple tows are intertwined with each other. Along a second portion, one of tows is removed from being intertwined with the other tows and is relocated to an interior or an exterior of the braided sleeve. A third portion includes the removed tow being intertwined with the plurality of tows again. In this manner, the braided sleeve may provide coverage of preforms with varying diameters along the longitudinal axis of the preforms.

A braiding apparatus may comprise a braiding machine, a lower guide mechanism, and an upper guide mechanism. The lower guide mechanism may comprise a multiple-axis robot or a multiple axis-mechanism. The upper guide mechanism may comprise a multiple-axis robot or a multiple axis-mechanism.
Abstract:
Electrically conductive braided structures having resistivity are disclosed. In an embodiment a structure comprises a plurality of nonconductive bias tows formed of fibers of a nonconductive material and at least one conductive tow formed of fibers including at least one conductive material. The plurality of nonconductive bias tows and the at least one conductive tow are arranged to form a braided structure.
Abstract:
A braiding system having a plurality of mobile carrier devices movable under its own power, each mobile carrier including a plurality of wheels, a motor driving the wheels, a power source, a controller, and a pick-up unit having a receiver. Each of the plurality of mobile carriers has a tow carrier positioned in the receiver, and each mobile carrier is simultaneously movable along a virtual track-less path predetermined for each individual carrier, such that the simultaneous movement of the mobile carrier devices along their predetermined paths form a braid.
Abstract:
An energy-absorbing deformable tube having a first end, a second end, and a reduced portion there between, a proximate tube portion between the reduced portion and the first end and a distal tube portion between the reduced portion and the second end, where a first cross section dimension in the reduced portion is smaller than a corresponding second cross section dimension in the proximal tube portion, distal tube portion, or both, and a cover spanning the reduced portion connected to the proximal tube portion and the distal tube portion, the cover provided over at least a portion of the reduced portion, the distal tube portion or the proximal tube portion or both moves relative to the cover after the deformable tube receives an axial force exceeding a predetermined threshold value.
