The two papers that are contained in this Report were given as pilot papers in October 1975 before the new group within the Structures and Materials Panel dealing with Composite Materials. The first of these papers points out and defines the three levels of materials data Acceptance data, Materials Characterization data and Design data that the author believes are needed to establish a design and manufacturing process that will allow the safe and efficient use of composite materials in aircraft. The paper points out some of the gaps between characterization and design, and it proposes some types of testing and data that may fill these gaps. It proposes that the present burdensome requirement that every primary composite component have its own development program can be eliminated if components are built in standardized ways from a finite family of layups and using previously developed structural elements. The second paper points out the vastly increased significance of the design engineeringmaterials engineering interface in the development of advanced composite structures. To achieve a smooth-working designmaterials interface, the paper suggests long-term emphasis in three specific areas education on the industrial level and also back to the colleges and universities interdisciplinary development of advanced composites and development of composites test standards.
