Temperature Influence on the Creep Behavior of a Carbon Fiber/Polyetheretherketone Composite

Carbon/PEEK Fiber Composites materials have, generally, a viscoelastic behavior and the mechanical properties are time dependent. These materials have gained an explosive use in the last decades, hence the need to determine their mechanical properties as accurately as possible. Generally, a composite with PEEK resin (having a viscoelastic response) has a creep behavior. In the paper the author proposes a model, using the last squares method, to determine the behavior of these materials under the effect of temperature. The results can be useful to engineers to estimate the effect of the temperature in different operating conditions.
