Patent ID: 8024908

Claim:
A hollow cylindrical structure, comprising: a repeating pattern of a plurality of alternating protruding components and intruding components forming an external surface and internal surface of the hollow cylindrical structure, wherein the repeating pattern of the plurality of alternating protruding components and intruding components of the hollow cylindrical structure provide tensile strength to the hollow cylindrical structure and wherein a shape created by the repeating pattern of the plurality of alternating protruding components and intruding components provides an optimal wind shear resistance for the hollow cylindrical structure; the external surface including the plurality of protruding components integrally connected to the plurality of intruding components with a plurality of curved connection components, wherein an individual protruding component includes two individual curved connection components connecting the individual protruding component to two individual intruding components and wherein the two individual curved connection components form an integral portion of both the individual protruding component and an integral portion of the two individual intruding components; the internal surface including the plurality of intruding components integrally connected to the plurality of protruding components with the plurality of curved connection components, wherein an individual intruding component includes two other individual curved connection components for connecting the individual intruding component to two individual protruding components and wherein the two other individual curved connection components form another integral portion of both the individual intruding component and another integral portion of the two other individual protruding components; the plurality of curved connection components each including a pre-determined curved connection component radius with two separate curved connection component outer radius portions forming two separate integral outer portions of an individual protruding component and two separate curved connection component inner radius portions forming two separate integral inner portions of an individual intruding component; a pre-determined hollow cylindrical structure inner radius from a center point to an inner portion of the internal surface; and a pre-determined hollow cylindrical structure outer radius from the center point to an outer portion the external surface, wherein the difference between the pre-determined hollow cylindrical structure inner radius and pre-determined hollow cylindrical structure outer radius determines a thickness of the hollow cylindrical structure, wherein the hollow cylindrical structure is a laminate pultruded hollow cylindrical structure created from a liquid resin mixture, reinforcing fibers and rovings aligned down a major axis of the hollow cylindrical structure, and wherein the hollow cylindrical structure includes a pre-determined length.
