COMPOSITE MATERIAL AND PRODUCTION METHOD THEREFOR

摘要

This invention concerns a composite material which is characterized by comprising a large number of composite material cells, as structural units of the composite material, each comprising a first phase composed of a base material and a second phase composed of a dispersion material surrounding the first phase discontinuously; and comprising a matrix comprising the base material and the dispersion material dispersed in the matrix, the dispersion material being dispersed discontinuously in the form of a three-dimensional network in the composite material; wherein the dispersion materials of the composite material cells are combined to form a composite material skeletal part, thereby exhibiting properties of the dispersion material without reducing the strength of the matrix owing to the skeletal part, and improving strength characteristics thereof owing to the skeletal part serving as a resistance to external stress. A preferred embodiment of the invention provides a composite material characterized in that it comprises a base material, a reinforcing layer comprising a material which resembles the base material and is dispersed continuously in the form of a three-dimensional network in the base material, and dispersion material which is dispersed discontinuously in the reinforcing layer, so that the dispersion material is dispersed discontinuously in the form of a three-dimensional network in the base material, and provides a method for the manufacture of this composite material.
