I have a nice source of GRP (glass reinforce polyester) pipes, which I'd like to test for wind turbine blades production.
There are many pipe diameters and wall thicknesses. I have a calc. for PVC blades from pipe, but it's for two blades. I'd like to go with 3-blade design (original one).
How to calculate.
Also, is anyone producing plastic (any kind, can be nylon, PVC, ABS, glassfibre, carbon...) blades for 10' wind generator?
