POLYHEDRON CELL STRUCTURE AND METHOD OF MAKING SAME

摘要

POLYHEDRON CELL STRUCTURE AND METHOD OF MAKING SAME OF THE DLSCLOSURE An open cell foam structure that has a negative Poisson's ratio. Structure can be created by triaxially compressing a conventional open-cell foam material and heating the compressed structure beyond the softening point to produce a permanent deformation in the structure of the material. The structure thus produced has cells whose ribs protrude into the cell resulting in unique properties for materials of this type.
