The material properties for composite material are different than typical isotropic materials, because different directions have different material properties. Also, monocoque typically have a sandwich structure consists of carbon fiber and aluminum core. Steps blow shows how to enter orthotropic properties into Ansys.
T300 Weave
Double click Engineering Data
Add a new material by click into the text box, and name the material "T300 weave"
To enter an orthotropic material property, go to Linear Elastic > (Drag) Orthotropic Elasticity onto the new material. A lists of property information will appear in the Property Outline as shown below:
...
This type of composite is weaved, so you have to define that as well, go to Physical Properties > (Drag) Density and Ply Type on to the new material.
In Property out line select Woven  from the pull down menu.
Next step, we need to define the stress limits and tsai-wu constants for failure analysis.
Expand Strength  > (Drag) Orthotropic Stress Limits and Tsai-Wu Constants on to the new material, and the properties are shown below:
...
following video shows how to mesh composite material and how to attach line bodies to surfaces
