GRP/FRP Plywood Panels
Marine grade fiberglass reinforced plywood
GRP/FRP plywood panels are composite materials that combine FRP (fiberglass reinforced plastic or GRP) with plywood. The sandwich panels are known for their strength, durability, cost-effectiveness, and environmental friendliness, making them an ideal choice for various applications.
Product Advantages
High Strength
FRP plywood panels offer excellent compression and bending resistance. They are not easily deformed under external forces, providing additional structural support, making them suitable for applications that require heavy load-bearing.
Durability
Enhanced by FRP, the panels offer superior corrosion resistance and UV protection, allowing them to be used for extended periods in harsh environments. They are especially suitable for areas with high humidity and intense UV exposure.
Cost-Effective
Compared to other high-strength materials, FRP plywood panels offer significant cost advantages. With mature production processes, they provide more efficient material utilization, making them a great option for projects with limited budgets but high-performance requirements.
Environmental protection
Plywood is a renewable resource. Compared with traditional wood, plywood has higher production efficiency and can make full use of wood resources, thus reducing waste.

Structural Diagram
FRP plywood panels are typical 3-layer sandwich panels with a middle layer of plywood and two outer layers of FRP sheets bonded together with adhesive.
Flat FRP Facing
The outer layers of the sandwich panel are made of GRP/FRP (fiberglass-reinforced plastic). These FRP skins are lightweight, corrosion-resistant, and highly durable, protecting the plywood core from moisture, chemicals, and physical damage. Our FRP surface is treated with a UV-resistant gel coat for excellent weather resistance.
Common Performance Parameters of FRP sheets
| Thickness | 1.0mm | 1.5mm | 2.0mm | 2.5mm | 3.0mm |
| Weight(Kg/m2) | 1.5 | 2.25 | 3 | 3.75 | 4.5 |
| Glass content(%) | 19 | 25 | 29 | 30 | 30 |
| Tensile strength(Mpa) | 60 | 80 | 92 | 95 | 97 |
| Elongation at break(%) | 1.5 | 1.5 | 1.5 | 1.5 | 1.5 |
| Elastic modulus(Gpa) | 5.5 | 7 | 7.3 | 7.6 | 7.8 |
| Izod impact strength(KJ/m2) | 45 | 55 | 70 | 80 | 95 |
Waterproof Plywood Core
The core of the sandwich panel is made of plywood, a strong and flexible wood product composed of multiple layers of veneer. Plywood provides the necessary structural integrity and rigidity to the panel. Our plywood is treated to be fire and water resistant and suitable for marine environments.
