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 tip end, a tail end and a pair of opposed edges, wherein said core member has a longitudinal axis extending in a tip-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 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 formed from an anisotropic material and 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 principal axis is oriented in a first direction that is non-parallel to each of said longitudinal axis, said transverse axis and said normal axis of said core member.
