Statistics for the time-dependent failure of Kevlar-49/epoxy composites: micromechanical modeling and data interpretation

Technical Report ·
OSTI ID:6348848
This paper presents some new data on the strength and stress-rupture of Kevlar-49 fibers, fiber/epoxy strands and pressure vessels, and consolidated data obtained at LLNL over the past 10 years. This data are interpreted by using recent theoretical results from a micromechanical model of the statistical failure process, thereby gaining understanding of the roles of the epoxy matrix and ultraviolet radiation on long term lifetime.
