Wind power blade, core material for wind power blade and manufacturing method thereof

The invention relates to a wind power blade, a core material for a wind power blade and a manufacturing method thereof. The core material comprises an insulating substrate and a plugging part, whereinfirst through holes distributed in a honeycomb shape are formed in planes of length direction and width direction of the insulating substrate; and the plugging part fills the first through holes of the insulating substrate and is provided with second through holes penetrating the thickness, and the second through holes are used for guiding a resin material which forms the wind power blade to flowin the thickness direction of the core material. According to the core material, as the insulating substrate for bearing and the plugging part which prevents the resin from seeping into the insulating substrate are independently arranged and are integrated, separately, a resin material is saved while the compressive strength of the core material is improved, the manufacturability of the core material is improved and the m
