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
