    Abstract

    Life estimation is crucial in designing fiber composite structures for long-term applications. To study this subject, in 1969 we started an experimental program using simple epoxy composites from S-Glass®, aramid (1971), and some graphite fibers. These impregnated fiber strands were tested for lifetimes (also called stress-rupture or static fatigue) under tension. We selected the strand specimens because they truly represented the basic building blocks of composite structures. As data became available, they were analyzed by different schemes and published during the last decade. In January 1980, a major earthquake in northern California destroyed most of our test specimens. For all practical purposes, this ended our approximately 10-year experiment. The purpose of this article is to review and analyze the available data on the S-Glass/epoxy composite and to make some final comments with regard to the long-term performance of this composite. Plots for life estimation and reliability assessment will be provided for engineering use.
