High Strength Commercial Grade Aramid Honeycomb Core For Industrial
Use
High Strength Commercial Grade Aramid Honeycomb Core For Industrial
Use is manufactured from DuPont Nomex® paper (or equivalent) and
coated with a heat resistant phenolic resin. It is widely used for
the high end industry for the purpose of higher strength and
lighter weight.
Features:
1. Excellent resistance to high temperature, therefore the core can
be used at a temperature more than 200 ℃ for the process of
autoclave;
2. The density range is ranging widely from 29-160 kg/m3 to meet
different capacity structure requirements;
3. It has extremely high shear strength, especially compared with
foam core material, which is more suitable for use in light
structure.
4. High toughness, high resistance to damage compared with other
honeycomb core materials;
Fire retardant, low smoke, low toxicity (in line with the most
stringent flame retardant and smoke standard of aviation);
5. Excellent creep and fatigue properties, can be used for the
medium and long term.
6. High humidity strength, can be used in high humidity
environment;
7. Easy to process, reduce production cost;
8. Corrosion resistant (not corroded by moisture or other medium
that is in contact with it, nor can it electrochemically react with
carbon fiber, like a metal honeycomb);
9. Superior insulation sound insulation, compared metal and glass
fiber materials;
10. Under the same weight, have better thermal insulation and sound
insulation performance, more comfortable and energy conservation
and environmental protection;
It is easy to process, and it is more convenient to operate than
the metal honeycomb.
