Modeling of strength degradation for fiber-reinforced polymer composites in fire

摘要: A model for predicting composite material strength degradation under elevated and high temperatures is proposed. This based on the morphology of mixture materials in different states. The resin-dominated shear can be well described by rule while nominal compressive tends to follow lower bound defined inverse mixture. Composite tension may exhibit fiber- or resin- dominated behavior. In a temperature range, fiber tensile strength, at higher temperatures, components failure joint regions. parameters required obtained basis kinetic analysis dynamic mechanical results. fitting experimental curves not necessary. proposed modeling scheme easily incorporated into structural theory predict responses time-to-failure. © 2009 SAGE Publications
