Advanced Accelerated Testing Methodology for Life Prediction of CFRP laminates

Conference paper
Part of the Conference Proceedings of the Society for Experimental Mechanics Series book series (CPSEMS)

Abstract

The advanced accelerated testing methodology (ATM-II) for the long-term life prediction of CFRP laminates exposed to an actual loading having general stress and temperature history is proposed in this paper. Three conditions as the basis of ATM -II are introduced with the scientific bases. The long term fatigue strength of CFRP laminate under an actual loading is formulated based on the three conditions. The creep compliance and time-temperature shift factors of matrix resin, which perform an important role for time and temperature dependence of long-term life of CFRP laminates, are also formulated based on the modified time-temperature superposition principle. The applicability of ATM-II is confirmed by predicting the long -term fatigue strength of CFRP laminates for marine use.
