摘要
Carbon fiber/epoxy resin composites have been widely used in many fields. However, they hardly melt at high temperatures or dissolve in any regular solvents. The recycling of carbon fiber/epoxy resin composites is one of the top research priorities. Carbon fiber/epoxy resin composite laminates consist of layers which are made of different materials. In near critical water, layers experience different forces, which result in the separation of layers and then accelerate the decomposition. In order to reach our final goal, decomposition of carbon fiber/epoxy resin composite laminates in near critical water, the characteristics of stress and strain of carbon fiber/epoxy resin laminates are necessary to know to guide the further study of decomposition. In this project, the stress and strain of carbon fiber/epoxy resin laminates in nearly critical water were analyzed using the ANSYS software. The results showed that temperature and pressure affected stress and strain of laminates differently in X and Y directions. In addition, the increased number of layers of laminates will increase the interlaminar shear stress, peeling stress, and the strain in Y direction, but will decrease the strain in X direction.
