Abstract: Firstly, the elastic modulus of CFRP laminate which is four-ply (45?/?45?/45?/?45?) lay-up was obtained from the uniaxial tensile test of strip, which has little difference with that theoretically calculated based on composite material mechanics, so it can be used as material parameters in numerical simulation and wrapping moment analysis. The wrapping experiment of CFRP laminate Lenticular Wrapped-Rib (LWR) was performed, and the strain in the LWR surface and the wrapping moment were measured during the wrapping process. By using ABAQUS package, the three-dimensional finite element models (FEM) were built to simulate the wrapping process of the CFRP LWR. The wrapping process is highly nonlinear, including large deformation, small strain and complex contact problems. The structural behavior characteristic parameters during wrapping a circle were obtained analytically and compared with experimental results, including the stress, the strain and the wrapping moment. As a result, a formula for the wrapping moment was given. Moreover, the effects of material lay-out and thickness of the LWR were analyzed, and the optimum material lay-out and optimum thickness were obtained. The numerical procedure and experimental results presented in this paper are valuable to the optimum design of LWR.
