A wet process for manufacturing a cloth prepreg with a uniform fibre distribution and large cover factor comprises impregnating a woven fabric with a diluted resin and drying, which fabric has a number of crossing points of warp and weft in the range of 2,000 to 70,000/m<2>, which process further comprises at least one of the steps (A) and (B), namely (A) a step of distributing a line-shaped binder on the fabric to fix the yarn flatness prior to impregnating the fabric with a resin diluted with a solvent, at least 80% of which solvent is a nonsolvent of the binder and, (B) a step of calendering the woven fabric after drying. <IMAGE> |
