Strength Analysis of Composite Material Underwater Vehicle

Abstract:

According to the design method of composite material mechanics based on laminate theory, structure of an underwater vehicle, which is made of twill woven carbon fiber composite material, was analyzed simulatively under the lifting condition with the finite element analysis software. Performance parameters of the laminated composite material were obtained from the mechanical performance testing experiment and applied to the analysis. In the two point handling condition, for the underwater vehicle structure, maximum deformation or displacement has a large safety redundancy to the test standard value. And the structure maximum stress is far less than the allowable strength limit of carbon fiber laminated plate acquired from the tensile experiment. It has an obvious advantage compared with metal frame structures.
