Fiberglass honeycomb panels combine strength, lightness, and durability, making them a popular choice in constructing various boat components. These panels consist of a fiberglass outer skin and a polypropylene honeycomb core, improving the structure and performance of the vessel.
They are often used in the following shipbuilding:
- Cruise ships
- Ferry
- Fishing boats
- Whaling boats
- Sailing boats
- Luxury yachts
- Rescue boats
- Speedboats
- Research vessels
Polypropylene Honeycomb
Polypropylene honeycomb is a lightweight, high-strength, chemical-resistant and moisture-proof material. Its excellent properties make it widely used in situations where weight reduction, strength improvement or pressure resistance are required. It also meets environmental protection requirements and has high recyclability. By using this material, the structural strength, building efficiency and durability of the ship can be improved while reducing the building cost.
TOPOLOGROUP supplies two different types of fiberglass marine honeycomb panels, designed for shipbuilding, with their own unique performance characteristics, suitable for different parts of the ship.
GRP Skin Honeycomb Panels
GRP panels have excellent flatness and high hardness. Usually, a layer of gel coat is coated on the surface to bring a bright mirror effect. The gel coat is available in a variety of colors, so GRP skin honeycomb panels have excellent decorative effects. Combined with high structural strength, they are widely used in various functional areas of large ships.
Typical applications include:
- Wall panels
- Partitions
- Ceilings
- Door panels
CFRT Skin Honeycomb Panels
Waterproofing of honeycomb panels in marine environments is an important challenge. Traditional adhesive bonding honeycomb panels perform poorly in such environments, especially in high-salinity environments, where honeycomb panels with thermosetting GRP skin are prone to debonding, despite edge sealing. Thermal bonding honeycomb panels effectively solve these problems. Their outer skin is CFRT (continuous fiber reinforced thermoplastic material). Since both the outer skin and the honeycomb core are thermoplastic materials, they are tightly combined through a thermoplastic composite process to form a solid whole. In addition, the panels are connected by laser welding to ensure connection strength and waterproofness, greatly improving their reliability and durability in marine environments.
Typical applications include:
- Hull structures.
- Decks and floors.
- Bulkheads.
