ABSTRACT:
A three-dimensional fabric is disclosed that includes a built in linkage member. The three dimensional fabric includes a core located in a center portion of the fabric. A multiplicity of axially extending warp yarns are arranged in a plurality of concentric layers about the core. A circumferential yarn is wound in a circumferential direction between various layers of the warp yarns to forming a plurality of circumferential yarn layers. A multiplicity of radial yarns are sequentially woven in the axial and radial directions about various circumferential yarn layers. A solid member is also provided which has a group of axially extending yarn strings secured thereto. The axially extending yarn strings include strings that constitute a portion of at least one of the core and the warp yarns. When the disclosed three-dimensional fabric is used in a composite, it is unnecessary to subject the composite to mechanical processing to attach a coupling part.
