Problem defining anisotropic material (CFRP)

My geometry is defined in two workplanes and one of them is rotated to the other. The material I want to simulate is carbon fiber reinforced plastic, thus an anisotropic material and it should defined on the geometry depending the coordinate system. Because of the angle between the two workplanes one should have a rotated coordinate system too. Also when defining an anisotropic material comsol puts in automatically the youngs modulus which I don't need when I can define the whole elasticity matrix.
So my Problem is to define a rotated coordinate system in the rotated workplane and how to enter an anisotropic material correctly regarding the right coordinate system. (For a plane structure it is easy to define the material with the ABD or anisotropic elasticity matrix.) Is there somebody with experience in defining fiber reinforced plastics in comsol?
I am grateful for any help!
Regards
