Abstract: The progressive failure analysis and residual life prediction of composite fuel tank are an important part of safety evaluations of RLV. In this paper, based on classical laminates theory, analytic and token models of composite fuel tank are built. By the finite element software ABAQUS, the progressive failure analysis is carried out and the residual life of a fuel tank is predicted. Compared with literature data, good agreements are obtained, which validates the methods proposed in the paper.
