Increased impact resistance capability is achieved in a cost and weight efficient manner by providing a spinner made of a 3-D orthogonal woven composite material. The spinner defines a generally conical shell having a plurality of axial rib stiffeners and at least one circumferential rib stiffener 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 delaminatio...
1. A spinner made of a three dimensional orthogonal woven composite material, said spinner comprising a three dimensional preform of woven continuous fiber tows having a generally conical shape with a plurality of axial ridges and at least one circumferential ridge interwoven therein, said spinner defining a generally conical shell having a plurality of axial rib stiffeners corresponding to said axial ridges and at least one circumferential rib stiffener corresponding to said circumferential ridge formed thereon.
