Shock absorbing component

A shock absorbing component which is configured with columnar structure comprising:

• a hollow columnar shaped body,
• wherein a side surface of the body includes a sheet-shaped longitudinal component formed by a plurality of sheet-shaped part materials provided thereon,
• wherein the plurality of sheet-shaped part materials includes a first part material and a second part material,
• wherein the first and second part materials are alternately arranged on the side surface and at least one of which is provided with at least one of a tensile maximum load characteristic, a tensile maximum displacement characteristic, a compression maximum load characteristic, and a compression maximum displacement characteristic,
• wherein at least one of the first and second sheet-shaped part materials is formed from a fiber reinforced material comprising a plurality of fibers,
• wherein the fiber reinforcement material is a sheet-shaped UD material and the plurality of fibers are aligned in a substantially same direction, and
• wherein the sheet-shaped UD material has a first sheet-shaped UD material provided approximately 0 degrees in a direction that is parallel to a longitudinal axis of the body, a second sheet-shaped UP material is layered on top of the first sheet-shaped UD material and in a direction that is orthogonal relative to the direction of the first sheet-shaped UD material, a third sheet-shaped UD material layered on top of the second sheet-shaped UD material in a direction that is approximately 45 degrees relative to the longitudinal axis of the body, and a fourth sheet-shaped UD material layered on top of the third sheet-shaped material in a direction that is approximately −45 degrees relative to the longitudinal axis of the body.

A shock absorbing component having a longitudinal direction and a lateral direction and which absorbs an impact force via a bending deformation that occurs approximately orthogonally relative to the longitudinal direction, the component comprising:

• a hollow body including at least one flat surface and one curved surface, each of the at least one flat and curved surfaces including a plurality of surface components formed by layered sheet-shaped components;
• a sheet-shaped longitudinal component formed by positioning at least two different kinds of sheet-shaped part materials, wherein the at least two different kinds of sheet-shaped part materials are characterized by one or more characterizations selected from a group including a tensile maximum load characteristic, a tensile maximum displacement characteristic, a compression maximum load characteristic, and a compression maximum displacement characteristic, alternately in the longitudinal direction, and wherein the sheet-shaped longitudinal component is implemented in at least a portion of layers of the surface components,
• wherein the sheet-shaped part materials are sheet-shaped UD materials having a fiber direction aligned in approximately a single direction,
• wherein the sheet-shaped UD material includes a first sheet-shaped UD material provided approximately 0 degrees in a direction that is parallel to a longitudinal axis of the body, a second sheet-shaped UP material is layered on top of the first sheet-shaped UD material and in a direction that is orthogonal relative to the direction of the first sheet-shaped UD material, a third sheet-shaped UD material layered on top of the second sheet-shaped UD material in a direction that is approximately 45 degrees relative to the longitudinal axis of the body, and a fourth sheet-shaped UD material layered on top of the third sheet-shaped material in a direction that is approximately −45 degrees relative to the longitudinal axis of the body.
