Below is a description of the most commonly used at Element 6 Composites. Honeycomb • Polypropylene Honeycomb: The advantages of the polypropylene honeycomb is that it is tough and durable, resulting in a strong impact resistant laminate.

Additional properties also include resistance to moisture, and high sound and vibration attenuation. • Aramid (Nomex) Honeycomb: Aramid fiber paper (for example, Nomex from DuPont Corporation) is an excellent lightweight non-metallic core material. Nomex offers excellent resiliency, low density, corrosion resistance, flame retardancy, and good compressive strength to weight ratio. • Kevlar Honeycomb: Like Nomex, Kevlar from DuPont Corporation is also manufactured from aramid fibers. However, the structural properties of Kevlar are better than Nomex, particularly in compressive strength. • Carbon-Fiber Honeycomb: Carbon-fiber can also be used as a core material; however, the cost is very high.

Structures with this type of construction are often limited to space applications, for example, satellites, where weight savings is critical, and the thermal expansion needs to be kept at a minimum. • Metal Honeycomb: Various metal honeycomb core materials are available, depending on the application. Aluminum is a common metal used for honeycomb cores, particularly when used with fiberglass face sheets. The compressive and shear strength of aluminum honeycomb are excellent.

Foams Foam cores produce extremely lightweight composite structures. Many different types of foams are available, depending on the application. In addition, foam volumetric density can range from as low as 1.0 lbs/ft3 to over 60 lbs/ft3. High density foam cores provide greater resistance to compression and crush, as well as provide damage tolerance from impact. Low density foam cores with carbon-fiber face sheets, particularly in thicknesses greater 1”, can produce panels with extraordinarily high stiffness to weight ratio. A few examples of foams cores commonly used in composite structures at Element 6 Composites are: • Airex Foam Core: Airex is a closed cell, cross-linked polymer foam, which is lightweight and has good impact strength. • Depron Foam Core: Depron is an inexpensive, non-structural foam.
