Abstract : The basic research panel was charged with the following questions: 1. How can we more effectively plan research targeted for the goals of this workshop? 2. How can we accelerate the adoption of cost effective advanced materials into Army systems? A non-trivial task is to address what assumptions must be made to provide for the materiel needs of the Army-After-Next. The success, or failure, of technology options chosen will impact strategic choices available to senior level Army planners. Several examples were cited from past industrial practice as models for technology insertion. Developments in electronics, specifically the exponential/logistics relationship between transistor density versus time and advances in materials strength-density vs. year were the examples provided. These are valid models for the private sector where perceived financial benefits are sufficient incentives; whereas in the Army mission performance has been the critical issue. Reduced resources, in combination with new requirements, has increased the emphasis on cost reductions for new systems. Today research, development and engineering planning can often be restricted to a linear paradigm that proceeds from one empirical solution to another. Based upon perceived strategic need, a better approach would be to predetermine the performance goals required for a given system and then go backwards to see what property requirements are mandated.
