| 摘要 |
The present invention relates to a sheet-form prepreg which comprises a plurality of carbon fibers and a matrix resin with which the plurality of carbon fibers are impregnated. This matrix resin contains a thermosetting resin, a curing agent, conductive particles of 1 µm or smaller in diameter, conductive particles of 5 µm or larger in diameter and thermoplastic resin particles, and the conductive particles of 1 µm or smaller in diameter, the conductive particles of 5 µm or larger in diameter and the thermoplastic resin particles are each disproportionately distributed in a specific part of the prepreg. By the present invention, a prepreg from which a carbon fiber-reinforced composite material having both excellent impact resistance and good conductivity in the lamination direction can be produced is provided. |
