fiber, were chosen for their low density and ability to dampen acoustic waves, making them commonly used as fillers in vehicle interior composite elements within the automotive industry. However, it is important to consider the temperature limit as a technological constraint in the natural fiber-reinforced composites industry, as it can lead to fiber degradation.
Abstract - Polyurea coatings have become an essential technology in the construction industry due to their remarkable properties such as rapid curing, durability, chemical resistance, and waterproofing. They are widely used to protect surfaces, structures, and infrastructure from wear and tear, which minimizes downtime and enables shorter construction schedules. These coatings are ideal for roofing, basements, and water containment systems as they create a flawless, waterproof barrier. They are also suitable for chemical processing plants, industrial facilities, and containment areas due to their exceptional chemical resistance. Moreover, their flexibility allows them to withstand temperature fluctuations without fracturing, making them ideal for extreme climate regions. Polyurea coatings can be applied to various substrates, creating a seamless, uniform finish. They are also used in industrial and marine settings to protect steel structures from corrosion. These coatings offer customization options for decorative and architectural purposes and can be designed for slip-resistant safety. Their longer service life reduces maintenance costs, making them a cost-effective solution for the construction industry
The study aimed to determine the adhesion force of polymeric coatings to steel bases, compare the impact resistance of multilayer coatings, and investigate the influence of the coating on static mechanical properties and fatigue lifetime. The most widely used strategy for fatigue lifetime improvement is strengthening metallic structures using CFRP (carbon fiber reinforced polymer) patches. Polyurea, also known as polyurea elastomer, is a modern construction material with extraordinary properties, such as high durability and strong resistance to atmospheric, chemical, and biological factors. Polyurea coatings are used to protect steel structures against corrosion from exposure to saltwater and other corrosive elements. They provide customization options for decorative and architectural purposes, including color, texture, and thickness. They can also be designed to be slip-resistant, enhancing safety in areas where traction is crucial. Polyurea coatings have a longer service life than other coating systems, resulting in reduced maintenance costs. In conclusion, polyurea coatings have revolutionized the construction industry by providing a robust and versatile solution for protective and decorative applications. Their exceptional properties, such as durability, rapid curing, and resistance to chemicals and environmental factors, make them an invaluable asset in constructing longlasting, resilient, and safe structures.

1. INTRODUCTION Polyurea coatings are widely used in industries such as construction, automotive, and marine due to their durability, fast curing time, and versatility. These coatings, including polyurea, polyurethane, and polyurethane-polyurea resins, serve as effective anti-corrosive and anti-wear agents, protecting against abrasion, tearing, and scratches. They can be applied on various surfaces, including metal, wood, concrete, and plastics, offering both decorative and specific mechanical properties. Additionally, polymers like polyurea are utilized as cover layers for armored vehicles, ballistic shields, loading areas, and waterproof surfaces, while also providing vibration and sound absorption capabilities. To enhance the properties of polyurea coatings, modifications with glass fabric and hemp fiber are employed. The application process involves sandblasting or the use of an epoxy resin-based intermediate layer. In this study, an epoxy resin intermediate layer was utilized, and the primer was modified with glass fabric and hemp fiber to improve impact resistance and vibration absorption. Samples with and without the polyurea layer were prepared to assess the influence of each constituent. Natural fibers, such as hemp

Polyurea is a highly durable and elastic material that is created through a reaction of polyamine and isocyanate. It consists of a chain-type structure with "n" molecules that are strongly combined, giving it its exceptional properties. Originally used in ballistic systems and devices for its energy absorption capabilities, polyurea has found numerous applications in the construction field. It is commonly used as a hydro-isolation coating for industrial floors and as a strengthening coating for steel and concrete. This elaboration focuses on presenting polyurea as a construction material, considering both its advantages and disadvantages. Additionally, it summarizes the current research on the material and explores future directions and areas of use
