Determination of the Electrical Conductivity Tensor of a CFRP Composite Using a 3-D Percolation Model

In this paper a percolation model is used to determinate the electrical conductivity tensor of one layer of carbon fiber composite. For this kind of material, fibers are randomly distributed in the resin. To take into account this distribution a virtual 3-D material model is developed and coupled with a homogenization method to overcome the scale factor problem. The electrical conductivity tensor is then used to simulate the induction heating of a multilayer composite.
