Abstract
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.
Claims17
A ship which includes a plurality of volumes positioned within the ship, each of said volumes comprising:
- an inner wall structure
- an outer wall structure spaced apart from said inner wall structure to provide a space between said inner wall structure and said outer wall structure,
- means for maintaining said inner wall structure spaced apart from said outer wall structure and,
- an energy absorbing composition positioned within said space comprising between about 10 and about 60 volume percent of a hardened resin containing hollow microspheres and between about 90 and about 40 volume percent macrospheres.
