Abstract
For the tubular C/C-weaving composite is often loaded on thermotics and mechanics loads together in using, adopting the sequential coupling method, utilizing the finite element analysis software: firstly analyze the stress distribution on loading temperature and pressure loads together, the maximums and changing rules of displacement, stress and strain have been obtained. Based on the works above, further to analyze the thermo-mechanical coupling of different loads, the curves of displacement, stress and strain in the specified paths have been obtained, it shows that the influence from temperature on every parameters is little when loading on the larger loads. So come to the conclusion that the tubular C/C composite has good temperature stability and can be used in the condition of high temperature or temperature changes greatly.
