Abstract:
A core for a gliding board, comprising:an elongated, thin core member constructed and arranged for incorporation into a gliding board and having a nose end, a tail end and a pair of opposed edges, wherein said core member has a longitudinal axis extending in a nose-to-tail direction, a transverse axis extending in an edge-to-edge direction perpendicular to said longitudinal axis, and a normal axis that is perpendicular to a base plane extending through said longitudinal axis and said transverse axis, said core member including a plurality of vertically laminated anisotropic structures, said plurality of vertically laminated anisotropic structures including a first anisotropic structure having a first principal axis along which a mechanical property of said first anisotropic structure has a maximum value, said mechanical property being selected from the group consisting of compressive strength, compressive stiffness, compressive fatigue strength, compressive creep strength, tensile strength, tensile stiffness, tensile fatigue strength and tensile creep strength, wherein said first anisotropic structure is arranged in the core member so that it extends from at least one of said opposed edges of said core member, said first principal axis lying in a first plane extending parallel to the base plane and being oriented in a first direction that is non-parallel to each of said longitudinal axis and said transverse axis of said core member.
