Long-term Open-hole Compression Strength of CFRP Laminates based on Strain Invariant Failure Theory

摘要: This paper deals with the prediction of long-term strength CFRP structure components based on combined method strain invariant failure theory (SIFT) developed by Gosse and Christensen accelerated testing methodology (ATM) Miyano Nakada. The time—temperaturedependent master curves SIFT critical parameters are constructed tension compression tests for longitudinal transverse directions unidirectional under various temperatures time-temperature superposition principle which holds viscoelastic modulus matrix resin. These can be used predicting composite structures multi-directional laminations at any time, temperature. open-hole quasi-isotropic laminates is predicted using SIFT/ATM structural stress analysis finite element method. appli...
