can anyone help me how to model composite materials in ansys

I am doing my thesis on crack propagation and vibration analysis of
transmission shaft of a helicopter. I decided the material to be a glass
fiber-reinforced polyester polymer composite. I need to analyze this on
ANSYS. but previously I use Ansys only for monolithic mateials. I need
help how to input the fiber orientation angle, how to mesh and how to
apply the torque. if any one have full tutorial or step by step tutorial
please froward it. my email is ekuba2010@gmail.com. thank you
