  • Inorganic fiber substrates for exhaust systems and methods of making same
    Publication number: 20030165638
    Abstract: A method for rigidifying a fiber-based paper substrate for use in the exhaust system of a combustion device. In the method, a green ceramic fiber-based paper substrate is impregnated with an impregnating material. The impregnated substrate is fired to form a rigidified substrate that is suitable for use in the exhaust system of a combustion device. This rigidification process is performed at least once and, preferably, two or more times.
