Use
Alumina-silica (al2o3–sio2) fibers, frequentlyreferred to as ceramic fibers, are formed bysubjecting a molten stream to a fiberizing force.
Ceramic fibers were originally developed forapplication in insulating jet engines. now, thisis only one of numerous uses for this material.it can be found in aircraft and missile applicationswhere a high-temperature insulatingmedium is necessary to withstand the searingheat developed by rockets and supersonic aircraft.employed as a thermal-balance and pressure-distribution material, ceramic fiber in theform of paper has made possible the efficientbrazing of metallic honeycomb-sandwichstructures.
