This paper presents the history and progress to date of the Joint-Army-Navy-NASA-Air Force (JANNAF) Composite Motor Case Subcommittee (CMCS) efforts to develop standard test techniques for the determination of mechanical material properties of filament wound composite structures. The work is a joint effort including both government and industry members of the Test and Inspection, Design and Analysis, and Processing Panels of the CMCS. This paper provides a chronological sequence of events leading to the selection of the interim test methods, specimen geometry, specimen fixture selection, testing specifications, design of the ROUND ROBIN Test (RRT), processing specifications, manufacture of the test specimens, and manufacture of the test fixtures. This paper also describes the Nondestructive Testing technique used to determine the quality of the specimens, analysis of the NDE data, strain gaging of the specimens, and plans for statistical analysis of the data.
