Title: Shear transfer element

Abstract: Shear transfer elements can be formed by winding or weaving unidirectional fibers on a support structure. In a winding operation the support structure consists of two intersecting planes of winding mandrels with the planes arranged in angularly spaced relation. Each plane has two pair of mandrels with the mandrels in each pair located on the opposite sides of the line of intersection between the two planes. After the fibers are wound on the mandrels, each mandrel is axially disposed in the opposite direction relative to the other mandrel in the pair and also to the adjacent mandrel in the other pair in the same plane. Next, the fibers are pressed to form the shear transfer element. In a weaving operation, the support structure consists of a pair of pivotally interconnected frames. The fibers are woven onto holders on the sides of each frame extending parallel to the pivot axis of the frames. After placement of the fibers on the frames, the frames are pivoted apart and the fibers are pressed to form the shear transfer element.
