Resin developed by scientists to repair damaged wind turbine blades
YU Polymer Materials Engineering Faculty Member Prof. Dr. Within the scope of the project "Development of Fiber Reinforced Composites with Fast Curing Epoxy Matrix with Visible Area Rays" in which Mehmet Atilla Taşdelen and research assistant Cenk Kurtuluş were involved, resin was developed for the production of composite materials.
With the project supported by TÜBİTAK's Rapid Support Program, it is aimed to repair the wind turbine blades that provide electrical energy from the wind in as short as 10 minutes.
Taşdelen said that composite materials are a new type of material obtained by combining at least two different components and are used extensively in daily life.
Noting that the composites used since the 1930s are now preferred in many different applications, Taşdelen stated that they are frequently used in the energy, transportation and automotive sectors.
Taşdelen stated that they wanted to bring the resin, which they developed the curing mechanism, to the technology within the scope of the project.
"The area we aim to apply for the first time is the repair point of wind turbine blades. As you know, the assembly of these turbine blades requires a very laborious process, and moving a blade of about 30 meters from one point to another is a very time-consuming and labor-intensive operation. We want to fix any damage on site and in a short time. We are considering repairing turbine blades damaged by environmental conditions or wild animals on site with this resin that we will develop. "
Taşdelen pointed out that disassembling and repairing a 30-meter wing and replacing it causes labor, time and excess expense loss, and said that the repair process can be completed without disassembly with the resin they developed.
"With this technology, we first clean the area to be repaired, then after laying the fiber on the damaged area, applying the resin on it, allowing the resin to harden with approximately 10 minutes of lighting and repair the turbine blade." Taşdelen said:
"These projects have to apply for TUBITAK Quick Support Program three months ago and was deemed appropriate support. Wind turbines in Turkey, as you know, was introduced in 2005 to implement and 2015 wind turbines in various regions with the support of our state was founded. Electricity, thanks These turbines We want to bring light-cured epoxy resin composite materials to domestic producers with the project we have developed to facilitate the work of these producers. Thus, we want to solve the damages on wind turbine blades in a very practical way. The shelf life of composite materials is 50 years. Of course, over time, there may be damages caused by both environmental conditions and wild animals. Although it seems like small damages at first, these damages can prevent the use of that wing. we work. "
Taşdelen explained the application stages of the resin as follows:
"After laying the fibers, we apply the resin on the fiber. Then, we use a low-energy light source to harden the resin. However, in the traditional curing method used today, heat energy is also used and this process can take 24 hours. Also, our goal is not only wind turbine blades, but also in the repair of large boats and yachts, we plan on-site repairs without dismantling. The convenience here is that you can apply the resin and repair it whenever you want. This is a convenience provided by ultraviolet light.
Research assistant Cenk Kurtuluş stated that the fiber-reinforced composite is ready with the lightening of the resin in a short time such as 10 minutes and said, "We can carry out the process with a simple 220 volt light source. In traditional methods, the hardening of the epoxy resin takes place at a high temperature like 150 degrees in hot presses and it is very serious. However, thanks to this resin we developed, we realize the hardening process in a very short time and with very low energy consumption. " said.
