How Do You Build A Wind Turbine Blade?
This article will help explain how to build a wind turbine blade, and the various steps required. This article will focus on larger wind turbine blades, 100kw turbines and larger. In the manufacturing of a wind turbine blades out of composite materials, one first needs a mold. Actually, two molds are needed as a wind turbine blade is constructed from two halves, which are bonded together. For this eHow, we will assume the molds are already made. In one half of the mold, lay the predetermined layers of fiberglass in the mold. Be sure that there are no creases or folds. Place core materials such as balsa or foam in the locations where extra reinforcement is needed. Often a spar is required, this is much like an I-beam that runs the length of the blade providing extra strength. Once all the fiberglass reinforcement and core material is placed, resin needs to be applied. This is done in either two ways; by hand using brushes and squeegees, or enclosing the whole mold in plastic and pulling
