Material of Turbine Blade
I continue my progress of making turbine.

Building my full size turbine from composite material chosen for 3 reason :

• Mechanical (Strength)
• Corrosion Resistance
• Cost

From characteristic above, I got several choice of material to make the turbine which is :
martensitic stainless steel, 3D printing or fiber glass. All 3 of this got its own pros and cons. Below shown the characteristic of each material :

From table above, there were many things that need to be considered before i make the decision. From what we can see, the easiest one to make the turbine is by using 3D printing. But, I am not sure if that turbine can works as the way as it need to be without affect its performance. If we want to make by using fiber glass, it need a very high cost and need to have a specific way of doing it. As for Martensitic Stainless Steel, it also have an expensive cost from making it. But it still can be make because it has a low weld-ability to making it. I still not making choice for the material of turbine since I did not done yet my research on it. After I done my research, I will inform at another day.
