Abstract
Method of making a reinforcing fabric comprising warps and woofs which are multifilament yarns made of carbon fibers. The widths W (mm) and finenesses D (d:denier) of the warps and woofs satisfy the equation: W=k.multidot.(D/.rho.).sup.5/9 wherein k represents 3.5.times.10.sup.-2 to 10.0.times.10.sup.-2 (mm.multidot.d.sup.-5/9) and .rho. represents specific gravity of the carbon fibers. The woven fabric has a cover factor K.sub.c of 90.0 to 99.8%. The fabric is made by treating a precursor fabric with water jets.
