You should also consider some other methods of modeling this stackup.

1. You could share topology in SpaceClaim or DesignModeler so that it meshes all these layers as node-connected. No contacts will be needed and material is perfectly bonded. 

2. You could use Ansys Composite PrepPost (ACP) to define the stackup, especially if material has orthogonal properties.

3. You could also just use one surface geometry at the top or bottom, and right click on Geometry to "Insert > Thicknes"

Turn on worksheet mode, and you can right click in the spreadsheet to add each layer. Specify the material, thickness and optionally, an angle orientation for each layer. This is a very efficient way to model the stackup.
