INVESTIGATION OF TECHNIQUES AND MATERIALS FOR THE FORMATION OF HIGH TEMPERATURE (1500 DEGREES F) INORGANIC FIBER
Abstract
Production of a high temperature (1500 F) inorganic fiber by forming the fiber with an organic matrix at a low temperature and firing this form to remove the organic part is discussed. The feasibility of the technique was demonstrated on a laboratory scale by continuously firing an organically-bonded fiber to an entirely inorganic form. The copolymer Acrilan is employed as the low-temperature fiber former and matrix. The inorganic materials consist of powdered silica or kaolin and low-melting frits. The service temperature of Acrilan was extended to overlap the temperature at which a low-melting inorganic material softens enough to bond. An entirely inorganic fiber 75 microns in diameter was fired continuously from a composite fiber composed of 25% Acrilan and 75% inorganic materials. Information was developed for selection of compositions and conditions for the formation of fibers with diameters down to 10 microns. (Author)
