Time-to-failure of randomly reinforced glass strand/urethane matrix composites: data, statistical analysis and theoretical prediction

摘要

This article concerns the time-to-failure ("static fatigue") response of randomly reinforced composites. The com- posites under consideration consist of swirl-mart and chopped glass fiber strands embedded in a urethane matrix, which are candidate materials for application in the automotive industry. The paper proposes a mechanics-based predictive model to relate time-to-failure to the magnitude off applied static loads.
