Anybody know how this is done? I want to do a stress analysis on a wing design, but COSMOSXpress yells at me when I choose to use a composite material.
When you say composite, what exactly do you mean? There are composites like chopped fiberglass that can be reasonably approximated with isotropic bulk properties. Then there are composites like garolite that have distinctly different properties in different directions - Xpress will not work with those. What sort of composite do you have?
So, I assume you're going to build a real wing? To test or to actually fly? Do you have a shop? Are there safety procedures in place for using nasty chemicals? Do you have some money available? Does anyone have composite experience?
You don't need to answer those now, but should know them when you come back.
Those are definitely benefits. However, since you are doing a study, make sure that you look into the costs associated with production, which are very large. Things to consider are the costs associated with the purchase and operating a large autoclave. Environmental and operational changes for the use of chemicals not normally associated with standard production methods. These costs are definitely not trivial, especially for a company that wishes to change or add the composite capability to their current ones.I'm on a design team doing a trade study on an existing wing design to see if we can make it better. Obviously, composites is a good thing to investigate, since they are stronger, you can lower the weight of the wing and the amount of structure to support it.
