A fiberglass honeycomb sandwich panel is a composite material consisting of an FRP surface layer and a honeycomb core. FRP has properties such as corrosion resistance and anti-aging, and the honeycomb structure remains lightweight while providing strength.
Its excellent mechanical properties, insulation properties, and flame retardant properties make it widely used in vehicle manufacturing, architectural decoration, advertising production, electrical equipment, and other fields.
Structure of Honeycomb Sandwich Panel
- FRP Layer: A gel coat covers the surface and allows for embossing into different texture patterns.
- Reinforcement layer (optional): Made of high-temperature-resistant glass fiber mat plastic. It acts as an isolation layer between the FRP material and the PP honeycomb core material, bonding them more closely and enhancing the strength of the honeycomb panel.
- Polypropylene Honeycomb Core: Polypropylene honeycomb core is available in different pore sizes and thicknesses. Honeycomb cores of different densities provide different properties: such as compressive strength, flexural strength, etc.
Performance of Fiberglass Honeycomb Sandwich Panel
- Lightweight
Due to its honeycomb structural core, Fiberglass honeycomb panels are extremely lightweight, providing excellent strength and stiffness at a relatively low weight ratio.
- High Impact Resistance
It withstands general impacts without damaging the surface.
- Higher Bending Resistance
The hardness of FRP is higher, and FRP PP honeycomb panels will not undergo large deformation.
- Corrosion resistance
The surface layer of FRP has good corrosion resistance and is suitable for use in humid and corrosive environments.
- Easy to process
Compared with metal materials, FRP honeycomb panels are easier to process in various shapes and sizes.
