Finite Element Analysis of Carbon Fiber Laminate

摘要:

碳纤维材料作为一种优良的复合材料,越来越广泛地应用于水下攻防领域。 主要研究了有限元法对碳纤维层合板的分析。 首先介绍层合板理论,基于该理论对碳纤维层合板模型进行理论分析,然后利用大型有限元软件 ANSYS 对同一模型进行有限元仿真计算。 最后,对二者计算结果进行比较,讨论有限元法对碳纤维层合板的强度计算的可行性,为工程设计运用提供参考。

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.
