Abstract
A physical model to simulate the mesoscale morphology evolution of carbon fibre is established to characterize the thermal mechanical erosion behaviour of C/C composite in high temperature and high pressure gas flow. The process of mechanical erosion of single carbon fibre is calculated by the DSMC method. The fracture criteria and mesoscale mechanical erosion model of carbon fibre are developed by theory of mechanics of materials. Finally, an engineering method for prediction of mesoscale mechanical erosion is formulated, and the predictions agree well with the experiment results. 11 Refs.
