composite material and fiber angles for 3D elements

Hi every one.

I was working for a 3D model, where i want to assign the composite material like e-glass epoxy with different fiber angles at different regions (for example like leaf springs). I wanted it to do with 3D elements, with including the contact non linearity. Can it possible, i have done for 2D elements by creating the plys and assigning the thickness. but looking forward to do over with 3D elements.

please suggest.

Thanks & regards,
