ABSTRACT:
A core material for laminates is provided, which is formed of a substrate and a porous sheet laminated on the one side of the substrate, said substrate having slits which penetrate therethrough in rows at an appropriate interval. The core material permits no inclusion of air inside when laminated with an FRP and putty is filled in the core material, with a result that the putty not only functions as a reinforcing rib, but prevents water-containing phenomenon.
