  • Methods for forming articles having very small channels therethrough, and such articles, and methods of using such articles
    Patent number: 6939505
    Abstract: Channeled articles having very small diameter channels spaced very closely can be made by packing elongated cores in a fixture, clamping them, and then introducing matrix material around the cores. The matrix material is formed into a unitary body and solidified. The cores are pulled out, leaving open channels where they had been. Some core and matrix combinations will permit the cores to be pulled out. Others require a core release coating to be applied to the cores. The cores can be metal or ceramic or polymer, and the matrix can be metal or ceramic or polymer. The cores can be solid, or hollow. Rather than pulling the cores out, if they are polymer, they can be burned out. The matrix can be formed by liquid state, solid state, or hybrid liquid/solid state techniques. A related technique uses hollow cores, which are not pulled out, but which remain in the body after unification. For such tube-walled articles, the matrix can be formed similarly. Rather than insuring core release, core retention is required.
