COMPOSITE INORGANIC RESILIENT SEAL MATERIALS. Period covered May 1958 to May 1959. Project title: NON-METALLIC AND COMPOSITE MATERIALS. Task title: ELASTOMERIC AND COMPLIANT MATERIALS
Research was conducted on essentially inorganic seal materials exhibiting the desirable characteristics common to elastomers, combined with temperature and fluid resistance to at least 1000 deg F. Materials exhibiting this behavior are a prerequisite to the design concept of power transmission systems for future flight vehicles. Experimental screening tests were performed on composite refractcry materials to provide leads for new materials for ultimate static and dynamic seal applications. of the numerous refractory material composites tested, the graphite and molybdenum disulfide combinaticn approached the target objectives, but were rapidly oxidized in an air atmosphere at 1000 deg F. Materials consisting of stainless steel and molybdenum fibers made into a bonded skeleton of the destred shape and impregnated with various soft ductile phases, were fabricated and their properties studied. Tie properties of these composites differ from the base metals from which they are made, since the geometrical configuration imparts an ehastomeric like behavior to the composite. A longer period of research would be required for further experimental study to explore all the possibilities that these new composite materials offer. (auth)
