What Is an FRP Sheet?
FRP (fiber-reinforced plastics) sheets are composite materials made from a UV-curable resin matrix reinforced with glass fibers. Known for their ease of use, including the ability to be cut, drilled, and painted, these sheets are utilized extensively for structural repairs and enhancements, as well as for waterproofing and protection against environmental elements.
Uses of FRP Sheets
From reinforcing building structures and extending the lifespan of bridges and storage tanks to repairing automobile bumpers and enhancing corrosion resistance in marine environments, FRP sheets offer a versatile solution. Their waterproof, insulating, and corrosion-resistant properties make them ideal for a wide range of applications, including control panels, roofing, sluice gates, and swimming pools.
Principle of FRP Sheets
The core material of FRP sheets is epoxy acrylate or vinyl ester resin, which hardens under UV light. The incorporation of glass fibers enhances their mechanical strength, allowing these sheets to conform to the shapes of the surfaces to which they are applied once cured.
Characteristics of FRP Sheets
FRP sheets are celebrated for their straightforward installation, robustness once cured, and resistance to water, chemicals, and heat. They can be cured with UV light, including sunlight, making them adaptable to various environments. Some products are specifically designed to be environmentally friendly, avoiding VOCs and complying with food safety regulations.

How to Install FRP Sheets
Installation requires careful preparation of the substrate to ensure cleanliness and the absence of air pockets. Exposure to UV light or sunlight activates the curing process, with typical curing times ranging from 20 minutes under artificial UV to over 35 minutes in sunlight. Conditions such as weather can affect curing, making preliminary tests advisable. Post-installation, it’s important to manage exposure to prevent premature curing and address any potential odor issues from styrene in the resin.
