<p>A reinforcing fabric includes at least two sets of inlaid yarns (82, 84) formed of a relatively strong material, such as glass, interlinked with knitted yarn made of a more conformable material, such as aramid. The inlaid yarns follow paths through the fabric that extend to one and then another side of an axis that is generally parallel to a machine direction of the fabric. The inlay yarns contribute to the strength of the fabric and the knitted yarn to its conformability, each factor being adjustable with more independence than known in the prior art. The degree of flexibility in adapting performance characteristics of the reinforcing fabrics allows tailoring to a range of products, in particular pipes, hoses and pressure vessels. In one embodiment, particularly beneficial to glass inlays, changes in direction of the inlaid yarn are accomplished through gradual rotations of successive short inlay segments (87a, 87b, 87c).</p> |
