Wind Energy applications Epoxy resin is used in manufacturing the rotor blades of wind turbines. The resin is infused in the core materials (balsa wood, foam) and the reinforcing media (glass, fabric). The process is called VARTM, i.e. Vacuum Assisted Resin Transfer Moulding. Due to excellent properties and good finish, epoxy is the most favoured resin for composites.
The applications for epoxy based materials are extensive and include coatings, adhesives and composite materials such as those using carbon fiber and fiberglass reinforcements. The chemistry of epoxies and the range of commercially available variations allows cure polymers to be produced with a very broad range of properties. In general, epoxies are known for their excellent adhesion, chemical and heat resistance, good to excellent mechanical properties and very good electrical insulating properties, but almost any property can be modified
Epoxy adhesives and sealants will bond to a variety of substrates. They can cure at either room temperature or be accelerated with higher temperatures. General-purpose epoxies have limited utility in long-term, high-temperature service.
