Abstract
An approach using laminate Coefficient of Thermal Expansion (CTE) measurements and two measured elastic constants is applied to predict the elastic properties of PEEK-IM7 prepreg laminae. This study assesses the feasibility of the use of this method to compute elastic properties over a range of temperatures. Three-dimensional elastic constants of PEEK/IM7 are determined for the temperature range of 20°Cto 120°C. The results indicate good agreement with quoted values measured by standard techniques, at room temperature. Moreover, the technique allows the study of the temperature dependence of the elastic properties over a range of temperatures. Thus, the technique demonstrates an ability to generate elastic properties data for a transversely isotropic material, over a wide temperature range, which ultimately can be used for improved performance prediction of structural composites.
