Composite spinner and method of making the same

摘要

Increased impact resistance capability is achieved in a cost and weight efficient manner by providing a spinner (30) made of a 3-D orthogonal woven composite material. The spinner (30) defines a generally conical shell having a plurality of axial rib stiffeners (44) and at least one circumferential rib stiffener (46) integrally formed thereon. The combination of the integral rib stiffeners with the 3-D orthogonal woven composite material results in a substantially greater torsional stiffness. The use of the 3-D orthogonal woven composite material also eliminates delamination found in laminated composite spinners.
