| Abstract: | Research was done on durability of two common kinds of CFRP sheets and resins.Sixteen groups of sheets which are altogether 80 sheets were tested in recent 3 years. Durability to strength of CFRP sheets was investigated in nature aging environment of China.An average value of aging residual strength semi-experienced math model is used to study durability on fiber reinforced polymer under climatic conditions exposure of China. Nonlinear fit parameter is used in retain rate curve equation to predict service life of CFRP. Correlate parameters of residual strength average value residual equation about CFRP and resins in the southeast are regressed according to the math model of semi-experienced(the equation of average value of aging residual strength).Life-prediction can be estimated by the model.And it can be used for further researching and engineering designing reference. |
