AHN 7800 is an Commercial Grade Nomex honeycomb particularly suited for
use where resistance to corrosive attack and moisture are important. This
material exhibits good strength characteristics and is fire resistant.
It is available in a variety of cell sizes and densities to suit most purposes.
Typical applications include lightweight non-structural bulkheads for ships,
joiner panels, shelters, antennas, and auto body panels. This material
is not intended for aircraft or aerospace applications. This material also
exhibits good thermal insulation properties and also has good dielectric
properties. This honeycomb is easily machined, formed, and shaped and well
suited to adhesive bonding.
|
AHN 7800 is manufactured from a E78 commercial paper from DuPont
and does not have the mechanical properties and flammability resistance
levels required and specified for safety and performance in aircraft
end-users. Typical mechanical properties are listed later in this
document.
