HONEYCOMB POLYPRPOPYLENE
Perhaps the lightest weight core option, honeycomb materials are used in aerospace, military, high-performance marine, motorsports and other high performance applications. Honeycomb cores are manufactured from a wide variety of materials including, fire-resistant Nomex®, aluminum, and thermoplastics, most commonly, polypropylene.
These cores are available in a 8mm cell size with a varying degree of thickness to provide a wide scope of mechanical and thermal properties that perform in demanding and critical applications.

Understanding Honeycomb Panels
What is a Honeycomb Panel?
Typically 5 layers: Skin, adhesive, honeycomb core, adhesive, skin. Materials with high tensile and compression strength are best suited to being skins, i.e. aluminum, steel, fiberglass. Adhesive varies widely by application: high strength, high temp, low temp, etc.
Honeycomb Core: A variety of honeycomb cores are available per design requirements.
How Does a Honeycomb Panel Achieve Its Strength?
Honeycomb panel strength works much like an I-Beam, with the core being the vertical element and the facing being the flange, working together to create high shear strength. Like an I-beam, greater distance between skins (thicker core) will create greater strength.
- High strength skin reduces risk of tensile failure.
- Many cells reduce risk of buckling failure.
- Smaller cells reduce risk of climbing crush or peel failures.
- Core orientation and density can reduce shear failure.
Stiffer and Lighter than Single Sheet Laminate
The stiffness of Plascore Honeycomb Panels allows the end user to utilize less material and reduce weight. Stiffness increases exponentially compared to single sheet material. The use of honeycomb core(s) creates a dramatic increase in stiffness with very little weight gain.
How is Stiffness Affected by Changing Core Thickness?
Relative Stiffness
As shown below, when all 3 structures have equal weight, height and material, honeycomb panel has a stiffness 264% higher.
