The gelcoat layer serves as the protective barrier on the surface of the FRP, playing a key role in both the product’s aesthetic appeal and weather resistance. Made from specialized weather-resistant gelcoat material, it features a fine, dense texture that effectively seals out air, rain, UV rays, and corrosive acid and alkali mists. Not only does it offer a smooth, even surface with consistent color that resists fading, but it also possesses anti-aging, stain-resistant, and wear-resistant properties, ensuring it will not peel, crack, or yellow even after long-term outdoor use.
    The resin layer serves as the adhesive core and structural backbone of the FRP. As the matrix material, it firmly bonds all components into a single, cohesive unit. High-quality, industrial-grade unsaturated resin is selected for its excellent flow and penetration properties, ensuring a perfect bond between the glass fiber and gel coat and integrating the three-layer structure into a unified whole. Once cured, it offers exceptional toughness and stability, effectively absorbing external impacts while providing superior corrosion resistance, waterproofing, and leak prevention, thereby eliminating issues such as delamination or material detachment.
    The glass fiber layer serves as the structural framework of FRP, renowned for its exceptional strength-to-weight ratio. Utilizing high-purity glass fiber strands and mats, this layer is uniformly distributed within the resin through a multi-layer layup process. It significantly enhances the product’s tensile strength and compressive resistance, endowing lightweight FRP with hardness comparable to metal while avoiding the drawbacks of metal—such as deformation and rust—and thus serves as the core guarantee of FRP’s high-strength performance.
