A composite material containing inclusions of spherical shells in which each spherical shell encapsulates a rubber core with ferrite loading. The inclusions are embedded in a matrix material of syntactic foam. The spherical shells are made from glass and therefore acoustically transparent and in combination with the cores are statically stiffer than the surrounding matrix material. The composite material with the matrix material and inclusions allows the composite material to be acoustically dissipating with a stiffness in which the energy of forces associated with undersea platforms is resisted.

Pressure resistant anechoic coating for undersea platforms

A double hull marine vessel is provided which includes a syntactic foam-macrosphere composition between the inner and outer hulls which dissipates force applied to an outer hull.

Marine vessel construction

A warship is provided with a plurality of interior volumes defined by an inner wall structure and an outer wall structure spaced apart from the inner wall structure. The space between the inner wall structure and the outer wall structure includes a syntactic foam-macrosphere composition between the wall structure which dissipates force applied to an outer wall structure.
