Frequently Asked Questions

Composite Materials & Properties

What types of composite core materials does Element 6 Composites offer?

Element 6 Composites offers a range of core materials for composite structures, including polypropylene honeycomb (tough, impact-resistant, moisture-resistant, high sound/vibration attenuation), aramid (Nomex) honeycomb (lightweight, flame retardant, corrosion resistant), Kevlar honeycomb (higher compressive strength than Nomex), carbon-fiber honeycomb (very high cost, used in space applications), metal honeycomb (commonly aluminum, excellent compressive/shear strength), and several foam cores (Airex, Depron, Divinycell). Note: Carbon-fiber honeycomb is typically reserved for space applications due to its high cost.

What are the advantages and limitations of foam core materials in composites?

Foam cores produce extremely lightweight composite structures. High-density foams offer greater resistance to compression and impact, while low-density foams (with carbon-fiber face sheets) provide high stiffness-to-weight ratios. Airex foam is lightweight and impact-resistant; Depron is inexpensive but non-structural; Divinycell is medium-density and damage tolerant, ideal for impact/crushing resistance. Note: Depron lacks compressive strength and is not suitable for structural applications.

How do wood core materials compare to other composite cores?

Balsa wood offers very high strength and stiffness-to-weight ratio, especially end-grain balsa, which provides high shear, tensile, and compressive strengths. Birch plywood is denser than balsa, providing durability, compressive strength, and machinability. Note: Balsa is a renewable resource, but may not be suitable for applications requiring maximum compressive strength compared to metal or high-density foam cores.

Note: Some materials (e.g., carbon-fiber honeycomb) are best suited for space applications due to cost.

Can you share specific case studies of Element 6 Composites materials in action?

Element 6 Composites collaborated with International Climbing Machines to develop a composite chassis for a wall-climbing robot used in nuclear, airplane inspection, and wind turbine blade repair. For AAI Corporation, they engineered carbon fiber control vanes for UAVs requiring high tolerances. Remote Aerial Tripod Specialists Inc. benefited from carbon fiber gondolas and tail fins for unmanned airships, achieving significant weight savings. Frontier Electronic Systems used a composite electrical enclosure for marine defense, featuring waterproofing and EMI shielding. See case studies. Note: Not all case studies cover every material type.

Composite Materials

Many different types of materials are used to create composites. Below is a description of the most commonly used at Element 6 Composites.

contact us

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. A Depron carbon fiber foam core laminate has excellent strength and stiffness in bending; however, lacks the compressive strength and crushing resistance of a structural foam core.

Divinycell Foam Core: Divinycell foam core is a medium density structural foam with very high strength, often used for heavier duty applications where lighter density foams may not work. In particular, Divinycell H100 is an excellent damage tolerant foam, and is ideal for applications that require resistance to impact and local crushing.

Wood

Balsa Wood: Balsa wood, when used as a core material in composite fabrication, offers a very high strength and stiffness to weight ratio. End grain balsa provides exceptionally high shear, tensile and compressive strengths for its weight. Balsa is also a renewable resource, with typical balsa trees maturing to 90 feet in seven years.

Birch Plywood: Birch plywood is higher density than balsa wood, providing a durable final product with excellent compressive strength, resistance to local crushing, and machinability.
