FRP Panels (Fiber Reinforced Plastic) or Glass Fiber Reinforced Plastic (GRP) refer to composite construction materials produced by combining durable polyester-based resin with glass fiber. Glass fiber is a material with high flexibility and particularly strong heat resistance. On the other hand, plastic is flexible but lacks adequate mechanical strength. When these two materials are brought together using polyester-based resin through various molding techniques, ranging from simple methods to more intricate processes, a new generation of composite construction material with high mechanical, thermal, and chemical resistance, referred to as GRP, is obtained. These panels find applications in various sectors, from the construction industry to the energy sector, automotive, and maritime domains. Their flexible structure and durability allow them to withstand external factors, offering long-lasting solutions.
