Plywood is made from multiple layers of thin wood veneers, with two adjacent layers of veneers stacked perpendicular to each other. It maximizes the use of wood and reduces waste. However, pure plywood has low strength and waterproof performance, and the visual effect is not very good. For example, it is easy to rot in a humid environment and has a short service life. In order to solve these problems, bonding a layer of FRP (fiberglass reinforced plastic) on its surface is one of the effective methods.
Structure of Fiberglass Plywood Sandwich Panels
The plywood is laminated with FRP sheets using glue to form a strong sandwich composite panel. Its upper and lower layers are made of fiberglass, and the middle layer is plywood as the core. FRP plywood sandwich panels are corrosion-resistant, impact-resistant, and weather-resistant, and can be cut like ordinary plywood.

Impeccable Quality
- Fiberglass reinforcement gives the plywood a protective layer, which increases the impact load the plywood can bear.
- FRP has good waterproof performance. It only needs to seal the edge of the panel to effectively prevent moisture from entering the inside of the panel.
Application of FRP Plywood Sandwich Panels
FRP sandwich panels are mainly used in RVs, caravans, campers, mobile homes, box trucks, buildings, furniture, etc. Mostly used in wall panels, door panels, roof panels, floors, partitions and other parts.
Types of Fiberglass Reinforced Sheets
At TOPOLO, the special thing about fiberglass plywood is that you can choose not only thermosetting FRP, but also thermoplastic FRP (CFRT – Continuous Glass Fiber Reinforced Thermoplastic) as the skin material.
