A Model to Study the Creep Behavior of Carbon Fiber/Epoxy Resin Composites Under Temperature

The mechanical characteristics of carbon fiber and epoxy resin composite materials are time-dependent and typically show viscoelastic behavior. Since the use of these materials in engineering applications has increased dramatically in recent decades, it is necessary to ascertain their mechanical properties with the utmost precision. Creep behavior is typically seen in composites made with epoxy resin, which has a viscoelastic behavior. In order to ascertain how these materials will behave over time when exposed to temperature changes, the authors of this research suggest a model using the least squares method. The experimental results verify the accuracy of that model. Engineers may find the results helpful in designing novel carbon fiber-based composite materials with an epoxy resin matrix.
