AWEA Show Comming Up

One of the fastest growing aspects of the composites industry is wind energy. The majority of wind blades, especally MW scale blades, are manufactured using the resin infusion process. This process is not new, in fact it is very similar to what is used in boat building. However, a wind blade is not a boat, it is a aerospace wing that receives a tremendous deal of stress.

Some composite blade manufacturers have already run into problems, but I believe there will be more issues in years to come. Aerospace manufacturing techniques will be mandatory for the necessary life spans of the blades.

At the American Wind Energy Association (AWEA) conference coming up next week in Chicago, IL, I am sure there will be announcements of new manufacturing techniques.

Below is a video of the steps involved in the resin infusion process. Instead of the mold being a boat, picture a wind blade.
