Abstract: Fiber-reinforced polymer (FRP) roofing panels have gained significant popularity in the construction industry due to their lightweight, durable, and weather-resistant properties. This article aims to provide a comprehensive analysis of the manufacturing process and material composition of FRP roofing panels. By understanding these aspects, engineers, architects, and manufacturers can make informed decisions regarding the design, production, and implementation of FRP roofing systems.

3.1 Resins: Resins act as the matrix material in FRP roofing panels, providing cohesion and bonding between the reinforcing fibers. The most commonly used resin systems in FRP panels include polyester, vinyl ester, and epoxy. Each resin type offers distinct properties and performance characteristics, making them suitable for different applications. Polyester resins are widely used due to their cost-effectiveness, while vinyl ester and epoxy resins provide superior chemical resistance and mechanical properties.
3.2 Fibers: The reinforcing fibers in FRP roofing panels contribute to the material's strength and stiffness. Glass fibers are the most prevalent choice for roofing applications due to their excellent tensile strength and corrosion resistance. Other fiber options include carbon fibers, aramid fibers, and natural fibers such as flax or hemp. The selection of fiber type depends on the specific requirements of the roofing system, such as load-bearing capacity, thermal stability, and cost considerations.
3.3 Additives: Additives are incorporated into FRP roofing panels to enhance specific properties or facilitate the manufacturing process. These additives can include UV stabilizers, fire retardants, pigments for coloration, fillers for improving mechanical properties, and mold release agents. The addition of additives ensures that the FRP panels meet the desired performance standards and aesthetic requirements.
