Home » Materials » Polypropylene Honeycomb Panels
FRP honeycomb panels (also called GRP honeycomb panels)are lightweight yet strong composite panels. The core of these panels is made of PP (polypropylene) honeycomb, which provides excellent stiffness and strength while keeping weight low. The FRP (Fiberglass Reinforced Plastic) skins bonded to this core provide durability, corrosion resistance, and a smooth surface finish.
Product Features
Lightweight & High Strength
FRP honeycomb panels are a typical lightweight material providing extremely high strength-to-weight ratio.
Weatherproof
FRP honeycomb panels do not absorb water and can replace wood and steel in humid and rainy environments.
Structurally Stable
Thermosetting FRP is hard and can well maintain the stability of the honeycomb panel structure, and is not easy to bend or deform.
Weather resistance
FRP panels are added with anti-ultraviolet agents, which can withstand long-term exposure to strong ultraviolet rays without fading or decomposition.
Easy to clean
The surface of FRP is not easy to absorb dust, stains, etc., so it is very convenient to wash with water.
FRP honeycomb panels maintain an extremely flat surface.

FRP Facing – Various Surface Styles
FRP(GRP) Sheet is a high-strength material made of glass fiber and resin matrix through a composite process. It has excellent characteristics such as light weight, high strength, corrosion resistance and aging resistance. Its surface can be processed into various styles, such as glossy, matte, non-slip, embossed, etc.
Polypropylene Honeycomb
Polypropylene honeycomb is a lightweight, rigid thermoplastic plastic used as the core of sandwich panel structures. Like aluminum honeycomb, it is also recyclable. Different honeycomb cell sizes have different densities and provide different mechanical strengths.
| Cell size(mm) | 8 | 10 | 12 |
| Density(MPa) | 80 | 75 | 70 |
| Compressive Strength(MPa) | 1.66 | 1.58 | 1.47 |
| Compressive Modulus(MPa) | 45.7 | 41.2 | 38.9 |
| Shear Modulus(MPa) | 0.50 | 0.45 | 0.40 |
| Operating Temperature(℃） | -40-80 | -40-80 | -40-80 |
| Thermal insulation U value | 2.2 | 2.2 | 2.2 |
Application of FRP Honeycomb Panels
FRP honeycomb panels are commonly used in various industries as wall panels, roof panels, partitions, floors, etc. Such as:
- Dry cargo truck bodies.
- RV bodies.
- Trailer bodies.
- Marine floors.
- Portable homes.
- Office partitions.
- Airline boxes.
- Furniture such as cabinets, bed boards, countertops, etc.
Manufacturing and Processing
We are a professional FRP honeycomb panel manufacturer in China and provide customized services. Our factory is equipped with industry-leading composite panel production lines and adopts unique production processes to meet clients’ personalized design requirements.
- Extraordinary size customization: The size of the honeycomb composite panel can reach 12mx3.2m. (The current maximum size of the container is 40 feet (12.03 meters)
- One-piece vacuum composite process: The sandwich panel is laminated under high pressure in a vacuum environment. The surface of the panel after molding is flat and tightly combined, and the strength is far superior to the sandwich panel laminated in the air.
- Any shape can be processed: High-precision CNC processing can meet any personalized design needs and maintain the consistency of product precision.
