Intermediate material for FRP molding and fabrication process therefor

摘要

The present invention relates to an intermediate material for FRP molding comprising a prepreg containing reinforcing fibers and a matrix resin, and a substrate containing essentially no impregnated thermosetting resin composition, which is provided on at least one side surface of said prepreg, wherein a ratio (B)/(A) between a thickness (A) of said prepreg and a thickness (B) of said substrate is within a range of 0.1 to 2.5, its manufacture and a process for producing a fiber-reinforced composite material from this intermediate material.
