摘要

The accelerated testing methodology (ATM) developed by the authors is introduced for predicting the long-term life of CFRP laminates by using the static, creep and fatigue strengths of them measured at a short term and various temperatures. First, the time-temperature superposition principle (TTSP) held for the viscoelasticity of matrix resin is explained by using the viscoelastic model. Second, the master curves of these strengths of CFRP laminates in the wide range of failure time at a reference temperature are constructed using TTSP for the viscoelasticity of matrix resin. Third, the master curves of CFRP strengths are statistically formulated based on Christensen's viscoelastic crack kinetic theory. Finally, the applicability of life prediction by ATM is discussed for various CFRP laminates and structures.
