SDF Nomex Honeycomb – Aramid Core

SDF Nomex Honeycomb – Aramid Core CORE MATERIALS

Product Code: SDF-COR-013

ATA-NH aramid honeycomb is considered for aerospace, defence, UAV, radome and rail applications requiring high sandwich-panel stiffness at very low weight.

Why does it matter?

The product name alone is not sufficient. Cell size, density, thickness and L/W shear properties must be used together in panel design.

Selection checklist

  • Cell size and nominal density
  • Panel thickness and skins
  • L and W directions
  • Adhesive, cure temperature and pressure
  • Edge closure and insert details

See the Nomex honeycomb selection guide for comparison.

Technical Details

The TDS lists 3.2, 4.8 and 9.5 mm cell options and product codes from 29 to 144 kg/m³. Mechanical data are stated as guaranteed values from 12.7 mm specimens tested at room temperature.

Frequently Asked Questions

Which values are required to select Nomex honeycomb?
Cell size, density, thickness, sheet size, L/W direction, skins, adhesive and process conditions must be defined together.
How does performance change with density?
The TDS shows higher compression and shear values by grade, but weight also increases. Use the TDS row for the selected cell and density code as the design reference.
Can Nomex honeycomb be used directly in infusion?
The open-cell structure may draw resin. It should not be treated like a foam core without a suitable barrier, film, bonding and edge-closure design.
