Wind turbine blades: Here's what you can do with aging ...

Most turbine blades are made from composites, materials joined for their complementary properties. Today's wind-turbine blades are usually made of a glass or carbon fiber reinforcement in a polymer matrix. The composite is designed for optimal aerodynamic performance and lightweight durability. It is not designed for recyclability.

NASA MOD-0 prototype (a 38 metre diameter downwind two-bladed rotor developed in 1975) was initially made with aluminium blades, but soon due to structural problems wood blades were installed. Wood was used in the 80's in small (< 10 m.) blades, and can be still seen today as part of composite materials together with epoxy resins.
