materials used to produce blades. The blades of H-type VAWTs, also known as giro Mills, are particularly suitable for low-cost production, due to their simple shape (no taper, no twisting).
Wind power is the conversion of wind into the most useful species through wind turbines. Most modern wind power is generated electronically by converting turbine blades into electrical energy using an electric generator.
With a new machine with equal aerodynamic performance compared to existing blades, lowering production costs is a direct way to improve return on investment. Low production costs are usually obtained through a large series of production technologies. It has recently been suggested that larger VAWT farms farther apart may benefit from the power supply than existing HAWT farms. The market acquisition of this understanding will require the use of a very large volume of turbines (and blades), thereby increasing the need for production technology for large series.
In windmills wind power is used to convert equipment into physical activity, such as crushing grain or pumping water. Wind power is used on large wind farms on national power grids and in small turbines to provide electricity to rural or isolated areas.
1.1 MATERIALS USED
1. INTRODUCTION
a) CARBON FIBER
Horizontal wind turbines (HAWTs) have been the focus of much of the wind-related research over the past few decades and represent a significant portion of the installed capacity. However, research work on vertical-axis wind turbines (VAWTs) has continued in parallel, usually focusing on a smaller scale, where different configurations and methods have been proposed. It has been suggested that VAWTs are suitable for power generation under conditions where conventional HAWTs are unable to provide optimal efficiency, such as turbulent winds with a strong variation in the airway. Another important advantage is that VAWTs travel everywhere, receiving air in any direction other than any form of yawning. Recent research has also shown that it is possible to increase the global performance of VAWTs by establishing them with a strong sequence of rotating orientation. The rotating VAWT column was estimated to provide a 50% to 100% increase in power, compared to the same number of separate VAWTs, confirming the validity of the idea proposed by Daribi. In this way, VAWT farms can achieve higher power output per unit area (W / m2), and as a result, less space than HAWT equivalent farms. Other options to increase VAWT output power, such as inlet guide-vanes are also explored. Despite all the recent advances, VAWT economically has not yet competed against HAWT, due to its declining energy efficiency. In this work, we therefore focus on ways to improve their global profits, by investigating the

Carbon fibers or carbon fibers (excluding CF, graphite fiber or graphite fiber) are fibers of about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and are composed mainly of carbon atoms. Carbon fiber has several advantages including high durability, very strong strength, low to moderate strength, high chemical resistance, high temperature tolerance and low temperature rise. These structures have made carbon fiber very popular in aerospace, civil engineering, military, and automotive, as well as other competitive sports. However, they are more expensive compared to similar fibers, such as glass fibers, basalt fibers, or plastic fibers. To produce carbon fiber, carbon atoms are grouped together with crystals that are slightly aligned or aligned with a long fiber axis as the crystal alignment provides a high degree of power-to-volume (in other words, its magnitude). Several thousand carbon fibers are woven together to form a toy, which can be used on its own or woven into fabric. b) PVC Polyvinyl chloride is the world's third-largest synthetic plastic polymer after polyethylene and polypropylene. About 40 million tons of PVC are produced annually.
