Abstract:
A composite material consisting of:a homogeneous base material enclosing interstitial spaces, anda reinforcing layer consisting ofa reinforcing layer material andparticulates of a dispersion material dispersed discontinuously within said reinforcing layer material, whereinsaid reinforcing layer is dispersed continuously in the form of a three-dimensional network in the interstitial spaces enclosed by said base material,said reinforcing layer bonds said base material together strongly and retains said dispersion material strongly,said dispersion material is dispersed discontinuously in the form of a three-dimensional network in said composite material, andsaid reinforcing layer material is selected from a group consisting of an amorphous material of a crystalline base material; a material which has a higher density than the base material; an amorphous material or a single crystal material with properties identical to those of the base material; a material which has a smaller elastic modulus than the base material; a material which has a smaller thermal expansion coefficient than the base material and the dispersion material; a material comprising at least one element found in the dispersion material; a mixed material of the base material and its sintering aid; and a sintering aid for the base material and/or dispersion material.
