Abstract
A woven fabric to be used in formation of a composite material includes multifilament warp and weft threads. Each of the warp threads and the weft threads have a total weight less than 80% of the weight of the fabric. The woven warp and weft threads have O twist/m and a torsion no greater than an original torsion of the threads before weaving. Each woven warp and weft thread has a width over the entire length thereof that is greater than or equal to an original width before weaving. The fabric is woven to have a given weight per unit area and a fiber volume ratio that is approximately constant throughout the fabric and that is satisfactory for use of the fabric in a composite material. The warp and weft threads of a yarn count that is greater than a yarn count traditionally used to achieve the fiber volume ratio for the given weight per unit area.
