APPENDIX I WORKSHOP PURPOSE AND PROGRAM (From Program Announcement) PURPOSE AND SCOPE The broad field of polymer science and engineering offers many opportunities for major advances. There are many products that fall short of military and NASA requirements. In the case of polymeric adhesives, there are both problems and promise. Some restricting factors are the limited ability to withstand high temperatures (above 350Â°C), cryogenic temperatures, and cyclic loading. The ability to detect "weak" bonds and to predict service life are both very poor, and technology development is needed before more structural uses develop. Interesting new polymers have recently been developed, and understanding of surface science is improved. Therefore it appears that major advances in adhesive joining technology are possible that can lead to useful and needed products. Adhesive formulations alone are not at issue. As reflected in the workshop program, advances in evaluation, stress analysis, and interface reactions can all lead to progress in the field. The unclassified workshop will highlight some of the opportunities to permit the committee to make recommendations to DOD and NASA as to promising research directions.
