Hi, If I have the following facesheet stack up -
And -45/+45, CSM is biax, can I add is as biax or I have to split the facesheets.
This is how my orientation and material is at the moment. Is it correct or is there a better way?

If some layers are supposed to have bidirectional fibers, you could add a new orthotropic material with proper stiffnesses in those directions (defined as orientations).
I am not sure, I understand you correctly.
This approach to composites modeling accounts for the presence of the fibers only by specifying material properties in two in-plane directions. Normally, you would have fibers (and this proper elastic modulus) in the first direction and then the second direction would be perpendicular to the fibers.
Here you can have fibers (and proper moduli resulting from their presence) in both those directions:
Abaqus has bilamina elasticity to account for different moduli in tension and compression in both directions, here you have to use the engineering constants definition.
