Abstract:As an excellent composite material, carbon fiber is more and more widely used in undersea warfare. This paper studies the finite element methods for the analysis of carbon fiber laminate. Firstly, the laminate theory is introduced,and then the carbon fiber laminate model is analyzed based on this theory. Next, the same model is carried out with finite element simulating cal- culation using ANSYS. Finally, the calculation results are compared with the theoretical results, and the feasibility of the finite ele- ment method for the strength calculation of carbon fiber laminate is discussed, which could provide reference for engineering design and application.
