Abstract The use of fiber‐reinforced composites in structures is discussed with emphasis on the need for a method to obtain long time properties from short time tests. Results of vibration, constant strain‐rate and creep tests are presented for boron epoxy laminates. The data is statistically conditioned and a time‐temperature shifting procedure is used to obtain master curves for response at an individual temperature. Three analytical linear viscoelastic characterization techniques are used to obtain long term creep response from dynamic data. Comparisons between analytical predictions are given for vibration and constant strain‐rate data. Creep predictions are also compared to experimental observations.
