Product Overview

Why Use Honeycomb Cores?

Honeycombs are some of the strongest structures found in nature. Their cells help provide superior strength while still remaining lightweight. Additionally, the cells have the ability to flex under compression and impacts. A critical failure from an impact will be limited in its spread by the core itself, which are able to flex and elongate instead of shattering like wood, metal, and other materials.

Furthermore, the cores themselves can be further strengthened with the addition of foam injection and facings.

Honeycomb Core by RhinoKore

​RhinoKore Honeycomb Core

Our RhinoKore lightweight honeycomb core really is the “core” of our business. With over a decade of fine tuning the art of foam filling our honeycomb core, RhinoKore has developed a quality structural honeycomb product with a multitude of sandwich panel applications.

The S150 is our synthetic honeycomb core and the P100 is our phenolic treated kraft paper honeycomb core. Both lightweight honeycomb cores are available foam-filled or unfilled.

​Foam Filled

Foam-filled lightweight panels

By filling honeycomb cells with foam, RhinoKore lightweight honeycomb core combines the natural strength provided by the cell walls of the honeycomb and the large surface area of foam. The cell walls of the honeycomb panel experience greater reinforcement and overall structural improvement when foam-filled.

Each of our lightweight honeycomb cores provide unique structural properties associated with the material used and how it interacts with the foam filling process. Substrate and skinning materials easily adhere to the honeycomb foam surface making this product an excellent sandwich panel core material.

Key Advantages

The net results for sandwich panels utilizing RhinoKore foam-filled honeycomb cores are:

  • Superior strength to weight ratios
  • Impervious to rot and moisture resistant
  • Thermal resistance
  • Dimensional stability
  • Sound and vibration dampening properties
  • Impact dissipation and damage resistance
  • Excellent shear and compression strengths
  • Significant price to performance ratios
