Title: COMPONENTS AND CORRESPONDING METHODS OF MANUFACTURE PROVIDING VIBRATION-DAMPING PROPERTIES
Abstract:
A manufacturing process and corresponding mechanical components are formed by additive manufacturing so as to include fully encapsulated cavities containing powder, typically deployed in distributed locations within the component, so as to increase the damping properties of the component compared to a similar component without such cavities. Since the filled cavities are completely enclosed, they do not impinge on the overall performance characteristics of the component and do not require maintenance.
