Is Nomex a composite?
For more than 30 years, the transportation industry has embraced honeycomb composite made with DuPont™ Nomex® for its excellent strength-to-weight ratio, which helps to provide vital cost-effective benefits like energy savings and payload increases.
What is a Nomex honeycomb core?
Nomex Honeycomb is a lightweight, high strength, nonmetallic honeycomb core material manufactured from aramid fiber paper with the typical hexangular cell shape. After the honeycomb is formed, it is coated with a heat resistant phenolic resin to increase its strength and thermal properties.
How is Nomex honeycomb made?
Nomex honeycomb is made from Nomex paper — a form of paper based on Kevlar, rather than cellulose fibers. The initial paper honeycomb is usually dipped in a phenolic resin to produce a honeycomb core with high strength and very good fire resistance.
Is honeycomb a composite?
Generally, man-made honeycomb structures are sandwich-structure composites with thin plates surrounding honeycomb cores. Depending on the situation, many different materials can be sued to construct the core including paper and thermoplastics for low loads or aluminum or fiber reinforced plastics for high loads.
What is Nomex insulation?
Nomex® 416 LAM is a paper designed for use in electrical flexible laminate insulation. It is produced in three thicknesses: 0.05 mm (2 mil), 0.08 mm (3 mil) and 0.13 mm (5 mil). Nomex® based laminates are used to create high-integrity electrical insulation for motors, generators and transformers.
Is Nomex a carbon fiber?
DragonPlate Nomex Honeycomb sheets are an excellent light weight composite sheet utilizing a Nomex Honeycomb core. Nomex honeycomb is the standard for lightweight non-metallic composite construction.

Why is a honeycomb structure so strong?
Due to the efficient hexagonal configuration, where walls support each other, compression strength of honeycomb cores is typically higher (at same weight) compared to other sandwich core structures such as, for instance, foam cores or corrugated cores.
Which honeycomb shape is best?
Bees could build flat honeycombs from just three shapes: squares, triangles or hexagons. But for some reason, bees choose hexagons. Always “perfect” hexagons.
Can we eat honeycomb?
And yes, the comb is totally safe to eat. People have been keeping bees — and eating the honeycomb — for several thousand years.
Why is honeycomb so strong?
The honeycomb cell shape is inspired by bees and the cells in the beehive, as the hexagon is one of the strongest shapes in nature. Thanks to the geometry of its shape, it means that the hexagon uses the least amount of material to hold the most weight.

Is Nomex conductive?
The thermal conductivity values for Nomex® 410 are similar to those for cellulosic papers, being primarily determined by specific gravity (density). Thus, thinner grades of Nomex® 410 have slightly lower conductivity while thicker grades have higher conductivities.
Does Nomex melt?
They also provide a high degree of heat resistance to the polymer backbone . As a result, Nomex® does not melt and drip, and merely chars when exposed to high temperatures for prolonged periods .
Is Nomex toxic?
The moisture barrier was a whopping 30% fluorine by weight. What hasn’t been discussed as much is Nomex Station Wear, and it’s just as toxic.
Is Nomex fire resistant?
Protective apparel made with Nomex® is inherently flame-resistant. The actual structure of the fiber itself is not flammable, which means the protection is permanent. The protection is built into the fiber itself and can never be worn away or washed out.
What’s the most efficient shape?
Hexagons are the most scientifically efficient packing shape, as bee honeycomb proves.
Is a circle or hexagon stronger?
The hexagon is the strongest shape known.
Is a hexagon stronger than a square?
The results of my testing were that the hexagon held much less than the square. This was because the mass on top of the hexagon was exerted onto the angles that were very weak. However, the mass on the square was exerted onto vertical lines, which is much stronger.
Does honey expire?
In general, honey doesn’t spoil. However, it can go bad if it’s contaminated or incorrectly stored. If your honey has visible mold, or if it smells fermented or “off,” then it’s time to toss it.
Can you eat raw honey?
It is safe for people to consume both raw and regular honey, though it is a good idea to avoid types of honey that contain added sugars. Both raw and regular honey may contain tiny amounts of a bacteria known as Clostridium botulinum. This bacteria can cause botulism, which is a rare form of food poisoning.
Is the wax from honeycomb edible?
Is honeycomb wax edible? Yes! Honeycomb wax is edible and perfectly safe to eat. The chewy, textural substance can be eaten on its own, used as a natural sweetener alternative, or added to a variety of foods and beverages.
How fire resistant is Nomex?
Can Nomex catch on fire?
Because cotton is a highly flammable fiber, Nomex®/cotton blend fabrics containing more than 20% cotton are not self-extinguishable [7,8]. A flame-retardant finishing procedure becomes necessary to make such blend fabrics fire-resistant.
Is Nomex a fire retardant?
Answer: Protective apparel made with Nomex® is inherently flame-resistant. The actual structure of the fiber itself is not flammable, which means the protection is permanent. The protection is built into the fiber itself and can never be worn away or washed out.
