Title: PREPREG, FIBER-REINFORCED COMPOSITE MATERIAL AND SURFACE-MODIFIED REINFORCING FIBERS
Abstract:
The present invention provides a prepreg which is composed of at least a matrix resin and reinforcing fibers, and which is characterized in that: conductive parts are formed on one surface or both surfaces of a fiber layer that is formed of the reinforcing fibers; and the volume resistivity ρ (Ωcm) of the fiber layer in the thickness direction, the thickness t (cm) of the fiber layer and the average interval L (cm) between the conductive parts arranged on the prepreg surface satisfy formula (1). Formula (1): t/ρ × 1/L × 100 ≥ 0.5
