Abstract

Abstract: The effects of surface-functionalized multi-walled carbon nanotubes (MWCNTs) on the fatigue properties of glass fiber reinforced resin matrix composites were investigated by tension-tension fatigue tests. Based on the test data, the linearizable exponential function and the power function S-N curve models were selected to quantitatively analyze the fatigue life of composites. The results showed that the fatigue properties of the aminated MWCNTs (MWCNTs-NH₂) modified epoxy resin specimens were better than those of the carboxylated MWCNTs (MWCNTs-COOH) modified epoxy resin specimens; while the fatigue properties of the MWCNTs-COOH modified unsaturated polyester resin specimens were better than those of the MWCNTs-NH₂ modified unsaturated polyester resin specimens. When the contents of MWCNTs-NH₂ and MWCNTs-COOH were both 0.2wt%, the fatigue properties of the modified composites reached the best. The correlation coefficient of the power function linear fitting results was higher than that of the exponential function linear fitting results, and the fitting accuracy was more accurate, and the fatigue life prediction results of composites of this model were also in good agreement with the test results.
