Abstract: A critical external pressure calculation method of 3D 4-step braided composite shell is presented in this paper. Two test results of critical external pressure for this kind of cylindrical shell are given. Calculation results are well consistent with test results. The calculation method presented in this paper has been proved and can be used in the design of this kind of composite shell.
