ABSTRACT:
A prepreg precursor including a carbon fiber woven fabric having applied to the fabric between about 0.5 to about 10 wt % of a stabilizer material for stabilizing the structural form of the fabric. Prepregs can then be produced using the woven fabric. Undesired settlement of matrix resin from 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 surface resin.
