Numerical simulation of the effect of electrochemical modification of 3D carbon fiber fabrics

The numerical simulation was adopted as a novel method to analyze the process and the effect of electrochemical modification of the 3D carbon fiber fabrics. A mathematical model of electrochemical modification of 3D carbon fiber fabrics was constructed on the principle of the macroscopic model. The mathematical model was used to simulate the process of fabric modification. The solution describes the treatment conditions of every part in the fabrics clearly and predicts the effect of the whole fabrics visually. The results indicate that the non-uniform modification existed in the fabrics, and the reason for this is the non-uniform distribution of the electrolyte in the fabrics. An intermittent electrochemical treatment method is raised to improve the effect of electrochemical modification of the whole 3D carbon fiber fabrics.
