Technology Base Enhancement Program Metal Matrix Composites Prepared by: BDM Federal, Inc. Prepared for: The North American Defense Industrial Base Organization (NADIBO) August 30, 1993 Foreword This report addresses the collection and analysis of technical, market, and policy information related to the world-wide Metal Matrix Composite (MMC) industry sector. The report includes information gathered from a wide variety of sources. Where appropriate, references are cited in the text in superscript format referring to the numerical listing of references presented in Appendix D. The report was prepared by BDM Federal, Inc. (BDM), 1501 BDM Way, McLean, Virginia 22102 for the U.S. Army Industrial Engineering Activity (IEA); the Productivity Branch, Industrial Base Division, Manufacturing Directorate, Wright Laboratory, Wright Patterson Air Force Base, U.S. Air Force; and the Directorate of Defence Industrial Resources of the Canadian Department of National Defence on behalf of the North American Defense Industrial Base Organization (NADIBO) under contract number DAAA08-91-D-0008. Ed Dorchak managed the MMC sector study. Principal authors were Michael Brown, David Fox, Mel Hafer, Donald Higgins, and Ellen Solos. The authors would like to express their appreciation to the many individuals throughout the U.S. and Canadian MMC community, from industry and within the U.S. and Canadian governments (see Appendix C) for their cooperation in providing essential information, thus making this effort possible. Special thanks go to Dr. Liselotte J. Schioler of BDM Technologies, Inc., for her review of the manuscript. - i - Disclaimer The mention of specific products or companies does not constitute an endorsement by BDM, the U.S. government, or the Canadian government.

In response to this challenge, the North American Defense Industrial Base Organization (NADIBO) sponsored the Metal Matrix Composites (MMCs) assessment as a case study to assess the potential for emerging technologies to continue to advance and to remain viable in the current and projected economic environment. This assessment provides a methodology and framework for conducting similar studies in the future and identifies opportunities to enhance the level of joint effort between the U.S. and Canada in creating and sustaining a viable MMC marketplace. Scope This study assesses the MMC technology base, detailing production capabilities, process and product technology developments, the current marketplace, and future potential markets and applications. Facilitators and barriers affecting the MMC sector are outlined, and roadmaps of actions designed to enhance MMC development activities and foster joint U.S./Canada activities in this arena are provided. In the course of this study, government, industry and academic representatives were interviewed and site visits were conducted. Figure EX-1 identifies the types of information gathered. An extensive database of the MMC and composite information was compiled.

Both the U.S. and Canada have a complex and interconnected infrastructure to deal with the science and technology base. Numerous government programs are offered by the countries to propel the advanced materials effort forward. Extensive foreign interest in MMCs, mainly from Europe and Japan, could begin to overtake domestic MMC capabilities. An increasing number of North American producers are being purchased by foreign companies. DWA and ACMC, which both receive Title III funding to develop MMC capabilities, are two examples of former U.S. companies that have been purchased by European and Japanese companies, respectively.

Applications of MMCs Significant technology advancement and policy barriers affect the MMC area, as defined in Table EX-4. Technology advancement barriers generally impede the use of MMCs more widely in new applications and in product improvements to existing - vi - Weight Reduction Wear Resistance Stiffness Tailorable Thermal Conductivity Increased Performance at Elevated Temperatures Tailorable CTE Corrosion Resistance Resistance to Radiation High Strength applications either due to lack of knowledge or confidence in MMCs or due to present limitations of MMCs. Policy barriers generally are economic disincentives which drive corporate decisions to invest either alone or cooperatively with other MMC participants. Facilitators that could prove of great benefit in advancing the MMC industry include the number of current and proposed U.S. policy initiatives and programs geared towards offering industry many incentives to becoming more involved in R&D activities, with emphasis on stimulating R&D partnerships, promoting technology transfer, and pushing dual use products. In regard to joint U.S./Canada efforts, the two nations have a number (approximately 2500) of agreements and programs in place to foster cooperative arrangements in the science and technology arena. Technology Advancement Barriers Policy Barriers Cost Large Capital Investment Required; Lack of Investment Incentives Lack of Commercial Applications MMC Producers' Profit Margin Considerations Lack of Standardized Test Procedures Government's R&D Focus on Technology Path Lack of Reliable Analytical Modeling Techniques Long Incubation Time Between Need Identification and Product Commercialization Lack of Widely Accessed MMC Government Policies and Regulations Material Techniques Lack of Federal and Industry Standards Lack of a Cohesive Planning Process CTE Mismatch Between Matrix and Intellectual Property Rights Concerns Reinforcement Lack of Nondestructive Evaluation Techniques Protection of Proprietary Information Lack of Repair Techniques Import Controls Lack of Recycling Techniques Transmission of Classified Data Table EX-4. MMC Advancement Barriers Goals Four goals for advancing MMC technology to support industrial base needs through joint efforts were identified: 1) Lower the cost of producing and using MMCs; 2) Improve communications between government, industry, and academia; 3) Improve the commercial viability and increase the commercial demand for MMCs; and 4) Strive to overcome the technical shortcomings of MMCs. - vii - Recommendations Recommendations designed to assist in fulfilling these goals are divided into two groups - general advancement recommendations, which are geared towards policy initiatives and apply broadly to all technology base advancement activities, and specific recommendations, which emphasize specific MMC technology plans. Figure EX-2 presents a roadmap with short and long term target recommendations to achieve general advancement strategies. These recommendations are organized under three strategies. Strategy One is to improve the economic viability associated with advancing new tech- nologies. Strategy Two entails improving communications between government, industry, and academia. Strategy Three involves improving MMC awareness and capabilities through improved education. Figure EX-3 presents a roadmap of specific technology recommendations separated into five discrete strategies. The five strategies are to: 1) create a low cost MMC insertion program for automotive applications, 2) develop a program to create military retrofit applications for MMCs, 3) develop a program to improve secondary processing techniques for MMCs, 4) improve production techniques for continuous MMCs, and 5) broaden the scope and improve the existing MMC design, analysis, and test techniques. - viii
