ABSTRACT:
A woven structure comprising at least a continuous band around an internal axis, suitable for impregnation with resin or for internal deposition of graphite from a reactive vapor, comprises axial threads, circumferential threads, and radial threads. The device employed to produce the structure comprises principally a series of flat rings or disks, aligned and slightly spaced from each other axially, having small apertures located around their circumference or one or more helical worms, with central openings, whose successive turns are similarly provided with apertures. Radial threads are passed through homologous apertures in successive disks, or successive turns of the helical worm, and are then drawn toward the central axis by wrapping of circumferential threads around them in the axial space between adjacent disks. Axial threads are then passed between the radial threads, and are drawn by further wraps of circumferential threads. The tightness of weave may be controlled by the tightness of wrap, permitting high porosity; or larger pores may be created by sacrificial insertions; and the process is particularly adapted to relatively stiff fibers, such as are desirable for reinforced structures. Solid insertions may be inserted as segments between the radial threads, or may be included as mandrels at the beginning of the weaving operation.
