Honeycomb is a lightweight core material which is available in a variety of cell sizes and densities, providing a wide range of mechanical and thermal properties. HexWeb® honeycomb provides a unique structure made from a variety of web materials including fiberglass, aluminum, and aramid/para-aramid mechanical papers.
Hexcel provides the largest variety of structural honeycomb to the aerospace industry. We produce more than 700 varieties with new versions being continually developed to meet customer demands. Honeycomb is an outstanding core material for sandwich structures. It is also used for energy absorption, laminar flow control, sound attenuation and dielectric applications.
Hexcel produces honeycomb using several production processes that enables us to offer a range of products and cell configurations that meet a wide range of requirements including formability, strength and stiffness for the customer’s application.
HexWeb® HRP-C fiberglass core for aircraft nacelle applications
HexWeb® HDC heavy density fiberglass for potting replacement in honeycomb sandwich panels
Aluminum core: 5052 or 5056 alloys with CRIII or CRPAA corrosion treatment options
Aramid/Para-Aramid (Nomex and Kevlar) core with phenolic dip coating
Glass: with phenolic or polymide dip coating
Flexcore for highly contoured applications
HexWeb® Flex-Core®, when compared to a standard hexagonal configuration, provides for exceptional formability into compound curvatures with reduced anticlastic curvature, and improved cell angularity to the contour part surface. HexWeb® Flex-Core® is offered in both Non-Metallic and Metallic materials. Highly contoured sandwich panels,
