Abstract: A prepreg precursor comprising a carbon fiber woven fabric having applied to the fabric from 0.5 to 10 wt% of a stabilizer material for rendering stable the structural form of the fabric. Prepregs can then be produced using the woven fabric. The undesired settlement, into the prepreg of matrix resin with which the fabric is impregnated in order to produce the prepreg and which is originally present on the surface of the woven fabric, is thus prevented. Hence, compared with a prepreg prepared using conventional woven fabric, a prepreg prepared by using the woven fabric of the invention can hold its tackiness for a long time and can be used to produce a fiber reinforced composite material excellent in smoothness without being devoid of the resin on the surface.
