Abstract
A structural member formed from a plurality of layers of interwoven fibrous material. The plurality of layers intersect and join each other along lines of contact. The lines of contact form axes of the member. A hollow central portion having a perimeter is defined by the plurality of intersecting layers and the lines of contact. A plurality of points are formed on the perimeter of the hollow central portion defined by the lines of contact formed by the axes. At least one flange extends outwardly of the hollow central portion at each of the points, wherein each of the plurality of layers extends beyond the axes of the member to define the flanges.
