Lewis Sloter, OSD Principal Reliance 21 Materials and Processes Community of Interest

Dr. Sloter described how the Reliance 21 Materials and Processes community of interest had worked with the DMMI to develop a workshop agenda covering the broad area of materials sustainability with respect to defense equipment, infrastructure, and recapitalization. Critical materials substitution and demand reduction were addressed at a previous DMMI meeting and remain a focus of DOD planning. Two weeks before this workshop, the Institute for Defense Analyses (IDA) held a workshop on issues related to specific materials and approaches to reduce vulnerabilities related to them. Sustaining adequate supplies of materiel, particularly with respect to equipment refurbishment and recapitalization, is currently important to planning for future utilization of the mine-resistant ambush protected (MRAP) vehicles fielded during Operation Iraqi Freedom. Normalization and global support for the F-35 Joint Strike Fighter aircraft is another highly topical issue, as is the broad subject of strategic manufacturing and local supply. Materials supply, utilization, certification, and substitution will be important aspects of Pentagon discussions on strategic sourcing, offshoring, and the control and prevention of counterfeit parts in the electronic and mechanical subsystems of critical defense systems. Dr. Sloter said these issues would provide grist for the materials research mill.

Dr. Sloter sees the twenty-first century as a time when material technologies will see significant advances. He expects rapid manufacturing in small volumes to be important in many areas, including pharmaceuticals, mechanical components, and electronic components. New manufacturing, printing, and templating technologies will be among the great opportunities to continue the advances reflected in Moore’s law for microprocessor-based systems. The difficulty will be in making the best use of limited resources to pursue the applied research and development (R&D) opportunities with the greatest potential benefits, given the broad range of opportunities and challenges.

Dr. Sloter was asked for his perspective on how much further improvement can be expected in structural materials, such as materials for hypersonic flight or other cutting-edge applications where material properties are a constraint. Are DOD
