METAL MATRIX COMPOSITES FOR SPACE SYSTEMS: CURRENT USES AND FUTURE OPPORTUNITIES

Abstract

Metal matrix composites (MMC’s) have fulfilled important space systems requirements for over 20 years. Current applications include structural members in the space shuttle cargo bay, a multi-functional antenna mast/signal waveguide in the Hubble Space Telescope, and electronic packaging for communication satellites in low earth orbit. The continued maturation of MMC technology, along with the expansion of new space systems concepts, now provides an unusual range of opportunities for the use of MMC’s in spacecraft. Enabling capabilities in liquid rocket propulsion are also being pursued. Both particulate- and fiber-reinforced MMC’s are being developed and evaluated for pump motor housings of liquid fuel rocket engines. Other liquid rocket engine components which are being pursued as a result of very attractive trade studies include inducers and impellers, cryogen ducts, lines and flanges, and the combustion chamber structural jacket. A novel approach for the manufacture of continuously-reinforced Al MMC’s is being developed to produce cryogen tankage. The suite of material characteristics that make MMC’s attractive for launch and on-orbit applications include very good specific strength and stiffness, high thermal and electrical conductivity, low-to-moderate thermal expansion, excellent resistance to UV radiation and good resistance to atomic oxygen. This balance of properties, and the fact that many of these properties are fully tailorable, offer unique opportunities for multi-functional use. Finally, the cost of MMC components, especially particulate-reinforced metals, can offer significant cost advantages over competing monolithic metals and organic composites. This manuscript will provide the results of a recent technology assessment of the space industry. The MMC systems offering the highest payoffs will be presented, and the impact on space systems will be described. Technical challenges to be overcome will be listed and a teaming strategy for materials development and insertion will be provided.

Introduction

Metal matrix composites (MMC’s) have matured in the past decade as an economically and industrially important class of materials. In 1999, the annual world production of MMC’s amounted to over 2500 metric tons, valued at over $100B US dollars [1]. Principle markets included ground transportation, thermal management, aerospace and recreation. MMC material is commercially produced by casting and powder metallurgy, and a wide range of secondary processes are established.

Metal matrix composites (MMC’s) consist of a continuous metal or intermetallic matrix phase and either continuous or discontinuous reinforcements. Continuously reinforced MMC’s offer the highest levels of strength and stiffness, but the transverse properties must be managed through either adjustments in the composite architecture or through selection of components with primarily uniaxial imposed stresses. Early space applications emphasized continuously-reinforced MMC’s due to the outstanding specific strength and stiffness along the fiber direction. While discontinuously reinforced MMC’s have emerged over the past decade as a pervasive material solution with a wide range of applications in other industries, the use of these materials in space systems has been slow to materialize. However, the strong current investment in a range of next-generation space systems now offers many opportunities for the development, demonstration and certification of MMC’s. This manuscript will describe the characteristics of MMC’s that make them attractive for a wide range of space applications. While a great deal of research and development has been conducted on very many MMC systems, this manuscript will emphasize MMC’s that are well-qualified and generally available on a commercial basis. The current uses of MMC’s in space systems will be outlined and applications that are being considered for MMC’s will be discussed. A brief description of the research and development required to achieve the properties goals needed for these applications will be provided, and this manuscript will close with comments regarding a proposed teaming strategy to expand the impact and to share the cost and risk of development and insertion.
