Abstract
Abstract A composite body consisting of a filamentary dispersion of metal within the pores of a porous body, the individual filaments having a maximum thickness of less than 200 angstrom units. A cathode is applied to a portion of the external surface of a nonelectroconductive porous body and the exposed portion of the cathode as well as a portion of the porous body adjacent to the cathode are covered with a nonelectroconductive protective coating. Metal ions from the anode traverse the pores of the body and deposit on the cathode resulting in the growth of metallic filaments which extend from the cathode throughout at least a portion of the pores of the body.

Total Claims: 2
Claim 1
Independent Claim
102 words
A composite body comprising a matrix mass of nonelectroconductive material selected from the group consisting of glasses, ceramics and plastics and a filamentary network of metal distributed through the matrix mass, said metal being selected from the group consisting of metals and metal alloys which are suitable for electrodeposition, the individual filaments of said filamentary network having maximum thickness of less than 200 angstrom units, said filamentary network extending outwardly from at least one surface of said matrix mass, the portion of said filamentary network which extends beyond the surface of said matrix mass consisting of a plurality of interconnecting metallic filaments.
