Materials System Research Laboratory, Kanazawa Institute of Technology 3-1 Yatsukaho Hakusan Ishikawa 924-0838, Japan The applicability of our developed accelerated testing methodology (ATM) based on the time—temperature superposition principle (TTSP) and others for the prediction of long-term fatigue life of polymer matrix composites is performed experimentally and theoretically. A formulation method of master curves of creep and fatigue strengths for polymer matrix composites is introduced based on ATM. The master curves of creep and fatigue strengths for the typical three directions of unidirectional CFRP, that is the longitudinal tensile and compressive loadings and the transverse tensile loading, are formulated using the data measured based on ATM.
Key Words: polymer matrix composites durability creep fatigue life prediction formulation.
