Abstract
A three-dimensional multiaxial circular woven fabric of a generally cylindrical shape having a core defined therein about a central axis. A plurality of concentric axial yarn layers extend radially outwardly in spaced-apart relationship from the central axis, and each of the layers comprises a plurality of axial yarns extending parallel to the central axis of the fabric. A plurality of radially spaced-apart circumferential yarns extend outwardly from the central axis of the fabric and define a plane substantially perpendicular thereto, and each of a selected number of the plurality of circumferential yarns is woven between a corresponding plurality of next adjacent and successive concentric axial yarn layers. A plurality of radial yarns is provided in the fabric wherein each of a selected number of the radial yarns is woven between a corresponding plurality of next adjacent and successive axial yarns and each axial yarn layer of a plurality of concentric yarn layers. Thus, each pair of radial yarns contains a radially extending row of axial yarns therebetween that includes a single axial yarn from each of a plurality of next adjacent radially spaced-apart axial yarn layers.
