Honeycomb panels for lamination
Honeycomb core panels for laminating lightweight composite structures
Nidaplast honeycomb panels are used as core materials in the manufacture of laminated composite parts.
Suitable for hand lay-up, resin infusion or spray-up molding, these panels provide excellent skin adhesion and a uniform distribution of mechanical stresses.
They are used across many industries, including transportation, construction, marine, technical equipment and industrial applications.
The extruded polypropylene honeycomb structure gives the panel high dimensional stability, complete rot resistance, and excellent moisture resistance.
Their low weight helps reduce the overall mass of composite parts, optimise production costs, and improve the mechanical performance of finished structures.
Our products
Nidaplast 8
Nidaplast 8 is the standard product in the range. It is suitable for hand lay-up or spray-up lamination processes.
Nidaplast 8DB
Nidaplast 8DB has been specifically designed to make the production of shaped parts easier. Its 30 × 30 mm checker-cut pattern on one side of the core allows the creation of curved components.
Nidaplast 8RI
Nidaplast 8RI is an ideal product for the infusion process. Its specially reinforced PP (polypropylene) film withstands resin pressure during processing and prevents the resin from filling the cells.
Nestaplast
These polypropylene panels serve as the core of bonded sandwich panels. Their surface coating (polyester non-woven and plastic film) provides an adhesion support for the applied facing layer.
Nidaplast 8FR
Nidaplast 8FR is an extruded polypropylene honeycomb containing a halogen-free approved material that limits flame propagation (flammability according to UL94 standards: V2 rating).
Nidaplast 8HP
Nidaplast 8HP is a polypropylene honeycomb designed to serve as the core of high-density structural sandwich panels.

Frequently asked questions
Which lamination processes are compatible with Nidaplast panels?
Nidaplast 8, 8 DB and 8 HP polypropylene honeycomb cores are compatible with most composite processes, including hand lay-up and spray-up molding.
Their structure ensures proper resin impregnation and strong adhesion between the skins, regardless of the chosen process.
Are Nidaplast panels resistant to moisture?
Yes. The polypropylene used is rot-proof and water-insensitive, ensuring mechanical and dimensional stability even in humid or marine environments.
This is a major advantage compared with other core materials such as balsa or certain polymer foams.
Can the panels be thermoformed or shaped?
Yes, Nidaplast panels can be hot-formed to create curved or complex shapes.
Nidaplast 8 DB, with its grooved honeycomb structure, provides increased flexibility during shaping.
This ease of processing makes it an ideal solution for molded parts, technical housings or hull panels in the marine and industrial sectors.
