This program presents flat specimen and tube mechanical performance data on graphiteepoxy composites. The experimental program was designed to study significant damage stress levels in these materials. The objective of the investigation was to establish an experimental definition of the stress level within a composite specimen at which physical damage andor degradation of mechanical properties are initiated such that the material resistance to subsequent loadings is seriously impaired. This stress level is referred to herein as the significant damage stress level. In addition related experimental methods were developed and a laminate strength criterion was compared with the experimental data generated. Author
