NORNS Polypropylene (PP) Honeycomb Core is a lightweight thermoplastic core material specially engineered for high-performance sandwich composite panels and lightweight structural applications. Produced via advanced continuous extrusion technology, its tubular honeycomb structure provides an exceptional stiffness-to-weight ratio, high compressive strength, superior shear performance and outstanding durability for modern composite structures.
As a premium alternative to conventional core materials including plywood, balsa wood and rigid foam, NORNS PP Honeycomb Core achieves substantial weight reduction while enhancing structural efficiency, impact resistance and dimensional stability. It is widely adopted for lightweight composite panels used in transportation, railway, marine, construction and industrial sectors.
Compatible with both thermoplastic and thermoset composite systems, the material can be laminated with FRP, CFRT, aluminum, steel, HPL, plywood and PP composite skins via continuous lamination, vacuum pressing, hot pressing and thermoforming processes. The thermally-laminated polymer film and non-woven surface ensure reliable bonding performance with a wide range of structural adhesive systems.
Featuring consistent tubular-cell geometry across the entire sheet, NORNS PP Honeycomb Core delivers stable mechanical properties, low resin consumption and high manufacturing efficiency, making it an ideal core solution for lightweight composite sandwich structures.
Open tubular polypropylene honeycomb core for composite sandwich structures. Lightweight, high-stiffness, moisture-resistant and fully recyclable.
PP honeycomb core with dual-sided surface coating / non-woven facing to enhance bonding performance, handling and sandwich panel production efficiency.
Advantages of the Tubular Honeycomb Structure:
Compatible with both thermoplastic and thermoset composite systems. The material can be laminated with FRP, CFRT, aluminum, steel, HPL, plywood and PP composite skins via continuous lamination, vacuum pressing, hot pressing and thermoforming processes.
