Title:
MULTIFUNCTIONAL ELASTIC METAMATERIAL
Document Type and Number:
WIPO Patent Application WO/2018/001234
Kind Code:
A1
Abstract:
Vibration suppression is achieved with a metamaterial composite structure constructed from three-dimensional resonant metamaterial cells. The cells have an inner mass formed of substantially incompressible material, with an elastomeric coating on an outer surface of the inner mass. An outer encapsulant formed of a material having substantially less elasticity than the elastomeric coating, and having less density than the inner mass is used to encapsulating the inner mass over elastomeric coating. The outer encapsulant supports the inner mass through the elastomeric coating with substantially no gap or fluid interface between the outer encapsulant and the elastomeric coating. The inner mass, elastomeric coating and outer encapsulant form a suspended mass structure.
