Abstract:

Statistically derived tabular design data to predict the estimated stress rupture life of unidirectional S-glassepoxy composites subjected to sustained tensile loading are presented. The maximum likelihood estimated life is tabulated for various stress levels of the fiber and quantile level. The lower bound lifetime with confidence intervals of 95 and 99 percent are also tabulated for the various fiber stress and quantile levels. The estimated lifetimes were calculated from accelerated stress rupture tests of uniaxial strand samples, therefore, the estimated lifetimes reported are considered to be conservative.
