Claims
- 1. A reinforcing fabric comprising warps and woofs which are multifilament yarns made of carbon fibers, the widths W, and finenesses D, of said warps and woofs satisfying the equation:
- W=k.multidot.(D/.rho.).sup.5/9
- wherein k represents 3.5.times.10.sup.-2 - 10.0.times.10.sup.-2 and .rho. represents specific gravity of said carbon fibers, said woven fabric having a cover factor K.sub.c of 90.0-99.8%, and wherein said warps and woofs are twisted to not more than 5 turns/m and each of said warps comprises not less than 3000 fibers.
- 2. The fabric of claim 1, wherein said fabric is a plain-woven fabric in which the finenesses of said warps and woofs are the same, each of said warps and woofs comrpises 3000 fibers.
- 3. The fabric of claim 2, which has a weight per an unit area of 120-250 g/m.sup.2.
- 4. A reinforcing fabric comprising warps and woofs which are multifilament yarns made of carbon fibers, the widths W, and finenesses D, d:denier, of said warps and woofs satisfying the equation:
- W=k.multidot.(D/.rho.).sup.5/9
- wherein k represents 4.5.times.10.sup.-2 - 10.0.times.10.sup.-2 mm.multidot.d.sup.-5/9 and .rho. represents specific gravity of said carbon fibers, said woven fabric having a cover factor K.sub.c of 90.0-99.8%, and wherein said warps and woofs are twisted to not more than 5 turns/m and each of said warps comprises fewer than 3000 fibers.
