Home > Composites > Fiberglass Reinforced Polymer Panels
Fiberglass reinforced polymer panels (FRP) are a composite material made by embedding glass fibers in a plastic resin matrix.
The glass fibers provide reinforcement, while the plastic matrix binds the fibers together, giving the material exceptional strength, durability, and flexibility.
FRP panels offer the advantage of greater resistance to corrosion, compression, and environmental factors compared to traditional materials such as steel and aluminum.
Features
- Yacht grade materials
- Anisotropic mechanical properties
- Prevent bulging
- Reduce attrition

Brief Development
The development of fiber-reinforced polymer (FRP) panels began in the mid-20th century, driven by various industries’ need for lightweight, high-strength materials. Initially used in the aerospace sector, FRP technology quickly expanded into other fields due to its versatility and superior performance. As resin and fiber technologies have advanced, the performance and range of applications for FRP sheets have continued to improve.
Structure of FRP Panels
Gelcoat layer: Gelcoat is a protective surface coating that provides a smooth, shiny finish to surfaces, making them more aesthetically pleasing.
Fiberglass Reinforcement Layer: High-quality thermosetting resin + fiberglass felt or fiberglass cloth.
Non-woven Fabric Layer: The non-woven fabric serves as a connecting layer, and FRP and other materials can be tightly bonded by spraying glue.
