Digimat predicts the electrical conductivity of multi-phase materials such as Polymer Matrix Composites (PMC), Metal Matrix Composites (MMC), Ceramic Matrix Composites (CMC), Nanocomposite, etc.

Electrical conductivity properties for Material Engineering applications

Electrical conductivity plays an essential role in aerospace and electronic applications. Nanocomposite materials are used in this field to improve or to limit the electrical conductivity of some components. The electrical conductivity of the material is then driven by the amount of nano fillers and the distance between fillers. This can be directly studied in both tools: Digimat-MF and Digimat-FE.

Digimat-MF to simulate electrical conductivity performances of composite materials

For all types of composite material, the electrical conductivity of the composite is computed by Digimat-MF by using the Mean-Field homogenization technique. Thanks to its ease of use, Digimat-MF constitutes as a virtual laboratory where a large number of materials can be tested in a very short period of time. The design of a composite material can then be optimized to reach specific targets.

Digimat-FE to simulate electrical conductivity performances of composite materials

A more in-depth analysis of the behavior of a composite can be performed in Digimat-FE. In this tool, electrical properties and percolation can be investigated. For instance, the effect of the amount of inclusions on the percolation can be studied in a fast and easy way. Percolation paths are tracked and displayed.
