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 cores themselves, 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 Panels by RhinoKore

​RhinoKore Honeycomb Panels

Our RhinoKore Honeycomb Panels really are the “core” of our business. With over a decade of fine tuning the art of foam injecting our honeycomb panels, RhinoKore has developed a quality structural honeycomb panel product with a multitude of sandwich panel applications.

The S150 core is our synthetic honeycomb panel and our P100 core is our phenolic treated kraft paper honeycomb panel. Both honeycomb panels are available with foam injection or without.

​Foam Injecting

Foam injected lightweight panels

By filling honeycomb cells with foam, RhinoKore honeycomb panels combine 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 by foam injection.

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

Key Advantages

The net results for the sandwich panels utilizing RhinoKore foam injected honeycomb panels 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
