  • Method for making vitreous fibers having small protrusions
    Patent number: 3953185
    Abstract: This invention pertains to a method of making inorganic vitreous fibers having small protrusions, such that the fiber produces a high strength reinforced molded product. The fibers are formed by introducing high melting constituents such as glass fiber, rock wool, ceramic fiber, silica particles, alumina particles, zirconia particles or mullite particles to molten inorganic material such that the constituents when flung from a ratary device are incorporated into the molten inorganic material.
