ABSTRACT OF THE DISCLOSURE A unidirectional reinforcing fabric and a resinous laminate made therewith, which fabric in- cludes a weft knit yarn fabric formed of a multi- plicity of weft knit stitches and a multiplicity of parallel longitudinally extending warp inserts held in said weft knit fabric. A bi-directional fabric is also disclosed which includes in addition to the above a multiplicity of parallel transversely ex- tending weft inserts. Each insert includes a multi- plicity of continuous monofilaments extending longi- tudinally in parallel relation with respect to one another without crimp or twist and grouped closely together so that the outline cross-sectional config- uration of the group is approximately in the shape of an elongated rectangle. Each monofilament of each insert is formed from a material taken from the group consisting of glass, carbon and aramid and has a cross-sectional diameter of between .00032" and .00095". Each insert has the thickness of the rec- tangular cross-sectional configuration thereof be- tween .003" and 0.38", the width of the rectangular cross-sectional configuration thereof between .009" and .75" and a ratio of width-to-thickness of be- tween 2 and 30. The total width of the warp inserts per yard width of fabric is between 55% and 98%. The total width of the weft inserts per yard length of fabric is between 55% and 98%.
