Abstract:
Considering the importance of epoxy polymer and the application of this material in the different industries, the study of epoxy stress-strain behavior at high temperatures is important. In addition, to study the epoxy-based composites micromechanically, it is necessary to know the temperature dependent mechanical behavior of epoxy. Therefore in this study, the stress-strain behavior of epoxy at different temperatures has been studied and discussed. Using a temperature dependent viscoelastic model, a constitutive equation has been developed to predict the stress-strain curve of epoxy at high temperatures. Using the presented model, the elasticity Modulus and strength of epoxy have been predicted in a wide range of temperatures. It was observed that the Modulus of elasticity and strength are sensitive to applied temperature. As the temperature increased, the modulus of elasticity and strength decreased sharply. These predicted results are compared with experimental results and they show a good agreement
