A composite material having a plurality of laminated polysilylenemethylene layers each having an inside region adjacent to a surface thereof in which nanoparticles of a metal of Au, Pt, Pd, Cu or Ag are dispersed. The composite material is produced by heating a layer of disilacyclobutane overlaid with a layer of nanoparticles of the above metal to polymerize the disilacyclobutane. The above procedure is repeated at least once more.

Composite material containing fine particles of metal dispersed in polysilylenemethylene and process for the preparation thereof

The present method of manufacturing a ceramic composite material, composed of matrix and reinforcing materials and an intermediate weak interfice material, creates a composite material particuarly intended for use at temperatures above 1400&deg; C. and in an oxidizing environment. The matrix and reinforcing materials consist of the same or different ceramic oxides having a melting point above 1600&deg; C. The interface material provides in combination with the matrix and reinforcing materials a stress field liable to micro aciding. The reinforcing material is immersed into a powder slurry containing carbon (C) and ZrO,so as to be coated thereby and then dried. After which, the thus created composite material is subjected to green forming and densifying steps. Finally, the composite material undergoes a heat-treatment in air leaving a porous structure of the interface material.
