These thicknesses are actually very close to what you would encounter on a real turbine.  

Both parts Wind turbine blades are made out of an orthotropic composite material with the following properties:now made of composite materials to reduce the weight of these massive machines. Here we simplify the structural analysis by assuming that the composite material can be approximated by the following orthotropic material properties. 

Density (kg/m^3)

1550

Young's Modulus-X (Pa)

1.1375E+11

Young's Modulus-Y (Pa)

7.583E+09

Young's Modulus-Z (Pa)

7.583E+09

Poisson's Ratio-XY

0.32

Poisson's Ratio-YZ

0.37

Poisson's Ratio-XZ

0.35

Shear Modulus-XY (Pa)

5.446E+09

Shear Modulus-YZ (Pa)

2.964E+09

Shear Modulus-XZ (Pa)

2.964E+09

Similarly, these values were given to us by ANSYS and they are also very These values are representative of composite properties found in real wind turbine blades.
