I am working on a project involving VAWT blades (about 20-30 cm long with 5-6 cm of chord length) manufacturing and I am looking for help in regards to:
1. Commonly adopted materials and manufacturing processes;
2. Very approx costs of such processes (at least orders of magnitude).
My interest lies in the blade manufacturing phase alone.
Any reference explaining and illustrating those points is very welcomed!
Thanks in advance.
E.g.: glass fiber+epoxy composites and vacuum bag processing
Process description? Costs involved?
Thank you very much for answering! They will surely be of help.
Luckily, I also found these two works, which are pretty much in line with what I am looking for. I am linking them as an extensive description of my question:
A lot of the issue is just the size of the run. Short runs let you do easily cast materials but they may not be as long lasting. Large runs give you economy of scale. I am familar with the referenced works above and it's a good start. A lot of it goes into the details.
