Quasi-static and cyclic bending experiments have been performed on unidirectional carbon fiber reinforced thermoplastic matrix composites. End-loaded dynamic data are reported for the first time in the present paper. An attempt has been made to systematically separate the effects of temperature and cyclic loading. A model was establish to enable the life prediction of the composite under combined fatigue and thermal loads. The incremental MRLife^TM philosophy was used to predict elevated temperature bending fatigue from elevated temperature quasi-static bending (stress rupture) and room temperature bending fatigue data. Encouraging results have been obtain for temperatures below the glass transition temperature of the material.
