A dimensionally stable filter structure for removing foreign and particulate material from high temperature fluids comprising at least one batt of relatively brittle, high temperature and corrosion-resistant fibers, said at least one batt being made up of fibers chosen from the class consisting of glass fibers, silica fibers, ceramic fibers, carbon fibers and graphite fibers, said at least one batt being stitched-knitted with high temperature, corrosion-resistant yarns such that said filter structure comprises said at least one batt encapsulated between two outer stitch-knitted layers of said high temperature, corrosion-resistant yarns integrally connected through said at least one batt at a plurality of stitch-through points therein. A process of making a dimensionally stable filter structure for removing foreign and particulate material from high temperature fluids comprising the steps of providing at least one batt of relatively brittle high temperature and corrosion resistant fibers chosen from the class consisting of glass fibers, silica fibers, ceramic fibers, carbon fibers and graphite fibers, and stitch-knitting said at least one batt with high temperature corrosion resistant yarns such that said filter structure comprises said at least one batt encapsulated between two outer stitch-knotted layers of said high temperature, corrosion-resistant yarns integrally connected through said at least one batt at a plurality of stitch-through points therein.
