Statistical Treatment of Aramid/Epoxy Stress-Rupture Data

Abstract

The purpose of this report is to provide statistically derived tabular design data to predict the estimated stress-rupture life of unidirectional aramid/epoxy composites subjected to sustained tensile loading. The maximum likelihood estimated life (MLEL) is tabulated for various stress levels of the fiber stress and quantile levels. The estimated lifetimes were calculated from accelerated stress-rupture tests of T.T. Chiao, who used uniaxial strand samples; therefore, the estimated lifetimes reported are considered to be conservative.
