I am Vishwajeet Karmarkar, part of a company called 12C Composites. We at 12C undertake custom orders for carbon fiber components. This post is to demonstrate our abilities to manufacture small to medium sized wings for various hobbyists requirements.
Making of the wing:
The wing order we received was a profile of NACA0015. The wing length was 2m, and chord length was 330mm. The client needed an aluminum ribs+spar assembly and carbon skins.(its also possible to make the rib+spar assembly in carbon).
Steps we utilized to build the wing:
1) Structural analysis: First step we undertook was to analyse the wing to prevent failure during operation. The carbon layup pattern, thickness, size of rib, spars was determined during this stage. Highly trained and experienced personnel(10+ years) , performed this analysis.(Licensed software)
2) Mold making: The wing profile was machined in MDF using a VMC. Various finishing operations with various easy to sand and gloss primers were performed on the mold.
3)Skin Layup: Once the mold was finished satisfactorily, the carbon skin layup was done.This was according to the layup pattern determined in the analysis report.
4)Ribs + spar assembly: 5XXX Series Al, was used to make this assembly. The ribs were laser cut high accuracy, and then welded using a TIG Welder. Highest level of quality control was ensured during welding.
5) Bonding: The rib+spar assembly was then bonded with the carbon skins using high strength structural adhesives.

I would love to hear your opinions and thoughts about this project. If you are interested in getting such wing blades in carbon, glass fiber feel free to shoot us a mail. Any other projects big or small, we have the team ready, right from design to analysis to manufacturing of your parts. We have a variety of techniques to manufacture wings, from the one demonstrated above, to skinning carbon on a foam core etc.
If interested please drop us a mail at
contact@12cccomposites.co.in . We would love to undertake any of your needs of carbon fiber, at reasonable costs! You can also call me on +919881201968
We also have developed a carbon fiber frame for 10 inch props. You can buy it here:http://www.flipkart.com/12c-miscellaneous-electronic-hobby-kit/p/itmegsuxgvppukbj?pid=EHKEGSUXYTA5JZGY.
