ABSTRACT:
A polar weave (i.e., three-dimensional, reinforced, composite material) flywheel, assembly comprises an outer polar weave portion and an integral metal hub. The hub includes a plurality of recessions and projections to provide an interface between the outer portion and the hub. The outer portion has a cylindrical configuration and is composed of woven and bonded unidirectional high-strength elements aligned and positioned in directions parallel to the polar coordinate axes. The elements so aligned are mechanically imbedded and locked into woven engagement with the recessions and projections, through which the woven outer portion becomes an integral part of the hub, and the interface is inherently strong enough to withstand failure caused by internal and external forces associated with operation of the assembly. The elements aligned and woven within the woven outer portion and onto the hub reinforces the assembly by providing the desired degree of strength and stiffness in directions of the polar coordinate axes, and prevents delamination from occurring in directions along the polar coordinate axes and in directions of the above acting forces. Reinforcement of the assembly also allows internal stresses to be controlled and optimized throughout the assembly when the assembly is subjected to the internal and external forces.
