ABSTRACT:
A method of manufacturing a non-metallic honeycomb having a perforated septum embedded therein in a plane extending perpendicularly to cell walls of the honeycomb, the cell walls of the honeycomb each having discontinuous opposite outer edge surfaces, including the steps of protecting the cell walls with a protectant mixture applied to one of the outer edge surfaces; and laser drilling the septum with a plurality of laser beams originating from a point exterior to the cell walls opposite the covered edge surface in a direction parallel to said cell walls and perpendicular to the plane of the septum, the protectant mixture covering an area of the outer edge surface sufficient to prevent damage to the cell walls.
