摘要：

The finite element model was used to predict the tensile strength of the self-lubricating fabric composites, and the wear rate prediction model of the composites was obtained. The unit cell finite element model of self-lubricating fabric composites was established by TexGen, and ABAQUS was used to perform finite element simulation of composites stretching, the tensile strength of the composites was verified by experiments lastly. The results show that the difference rate between the simulated value of the composites in the warp direction and the experimental value is 6.71%, and the rate of difference in the weft direction is 5.51%, indicating that finite element model of the composites has high reliability. From the tensile stress cloud diagram, it can be seen that the tensile strength of the composites is determined by the elastic modulus of the fiber in the tensile direction. On this basis, analysis of the wear rate and friction and wear mechanism of self-lubricating fabric composites, the mapping relationship between the tensile strength and the wear rate of the composites was studied. The difference rate between the predicted value of the wear rate obtained by the prediction model and the experimental result is 8.43% on average, indicating reliability of the volume wear rate prediction model. © 2022, Editorial Office of Acta Materiae Compositae Sinica.
