Lot of trying and testing has been done with regards to power generation from the greener sources. Wind power has emerged as a notable source of power generation on the global front in the recent past. To support it with statistically, it can be seen that, as per IEA 108 GW of energy was added to the world, with the help of wind in 2020. This number was twice the figure attained in the preceding year.
This lion leap for wind power would not have been possible without the use of high-tech materials. This blog will theow some light on the fact that, why composites play an important role in this regard.
Composites are Essential Ingredient for Wind Power
The most common design of the wind turbines is the one which has three blades rotating around a straight axis. The surface of the blade resembles an airplane wing, developing lift with air flowing over it. This pressure causes the blades to turn, spinning a shaft, which is connected to a generator. This converts wind’s kinetic energy into electricity.
The blades have gotten longer with the tech-advancement happening all over the world.
The reason, it is preferred to have longer blades of wind turbines is that larger turbines have improved efficiency than the ones with smaller blades. All the associated costs are similar to the smaller turbines, but the efficiency increases. Furthermore, the larger blades can tap into the stronger winds at higher heights.
These long blades have to stand tall for catering to demanding performance requirements. They should be stiff, strong, lightweight, and durable. Composites has all the qualities to become a raw material for the wind turbine blades.
What Composites are Used in Wind Turbines?
Turbine blades have got different parts. Internally, they have a beam for carrying load and provide solidity. This is attached to the two halves of the outer shell, providing the blade its shape.
The key t material in the blades is glass fiber strengthened polymer, frequently retaining epoxy resin or polyester. This is often called by the name, fiberglass, this combines strength and toughness with lightweight, perfect characteristics for this use.
The parts of the blades that are subject to much stress are often also made from carbon fiber reinforced polymer. As opposed to glass fiber, the latter is, stiffer, stronger and lighter. It is also a good conductor of electricity and its stiffness can decrease longevity. Due to these reasons, fiberglass is mainly used in the construction of wind turbine blades.
