The present invention has the following constitution. A resin composition for a fiber reinforced composite material comprising the components ÄAÜ, ÄBÜ and ÄCÜ are essential wherein the modulus of storage rigidity G' measured by parallel plates having vibration frequency of 0.5 Hz during elevation of temperature from 50 DEG C at 1.5 DEG C/min is in a range of 5 to 200 Pa in an entire range of 70 DEG C to 100 DEG C. A resin composition for a fiber reinforced composite material comprising the components ÄAÜ , ÄBÜ and ÄCÜ are essential, wherein the minimum modulus of storage rigidity G'min and the maximum modulus of storage rigidity G'max at 70 DEG C to 100 DEG C measured by parallel plates having vibration frequency of 0.5 Hz during elevation of temperature from 50 DEG C at 1.5 DEG C/min, satisfy the following relation: A resin composition for a fiber reinforced composite material comprising the components ÄAÜ, ÄBÜ and ÄCÜ are essential, wherein the thixotropy index is in a range of 2.5 to 40, the resin viscosity at 80 DEG C measured by parallel plates having vibration frequency of 0.5 Hz during elevation of temperature from 50 DEG C at 1.5 DEG C/min is in a range of 100 to 1000 poises, and the minimum value of resin viscosity during heating is 30 to 400 poises. A resin composition for a fiber reinforced composite material comprising the components ÄAÜ, ÄBÜ and ÄCÜ are essential, wherein solid rubber and fine silica particles are contained as component ÄCÜ by 1 to 10 wt%, respectively, based on the total weight of the resin composition.

    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.
