Abstract
A molded article comprises an outer interface element, an inner interface element, and a plurality of web spokes positioned therebetween. The common surfaces of the inner and outer interface elements and a pair of adjacent web spokes form a void space. The surface of at least a portion of an interface element common to one of the voids has an edge radius with a variation from a maximum radius at a circumferential location corresponding to a mid point between a pair of adjacent web spokes to a minimum radius at a circumferential location corresponding to the intersection of the interface element with the web spoke.
