material thickness of a naca0021 wing profile

[Dmaz]

Hello, everyone. I am studying a naca0021 profile of 86mm rope to be made of composite material (polyster with 35% content in fiberglass). the application is the shovel of a wind turbine vawt.
inside the profile is empty with a set placed to a third of the rope. do you know what the thickness of the materials used for these profiles (intensive as the thickness of the profile line) are? For example, he told me that if I made it in aluminium, it would be 2mm.
Do you know any company that produces them?
Thank you so much!

Excuse me, but are you a student in what exactly?

Do you have any idea what you're asking?

hi study mechanical engineering. In practice I have to do the structural analysis of a naca0021 profile wind blade. the model must be set with shell elements to which a thickness dependent on the loads in play. I wondered which thicknesses were generally used since I had no comparison elements.. However for this composite I was told 3-4mm thick. .

and without knowing the geometry of the shovel, nor the conditions in which it will work, nor the properties of the material or the loads as you think it will give you an opinion?
