Advances in Inorganic Fiber Developments

  • Ashok K. Dhingra


Inorganic fiber based materials offer potential for the develpoment of next generation advanced materials beyond fiber reinforced plastics. Inorganic fiber needs and technology are briefly reviewed. The difference in structure and properties of alumina and alumina/silica fibers are discussed. The addition of silica to alumina increases the tensile strength but significantly lowers the modulus of the 100% alumina fibers. Next generation advanced aluminum alloys based on reactive Al-Li compositions are shown to be compatible with dense microstructure and relatively stable 100% alumina fibers to yield wellbonded alumina fiber reinforced aluminum matrix composites having predicted mechanical properties. Examples of potential applications for inorganic fibers materials in aerospace and automotive are shown. An important milestone in inorganic fibers technology was recently reached with the introduction of the world’s first inorganic fiber reinforcedmetal matrix composite as a piston insert for an automotive diesel engine.
