Working with Nomex Honeycomb (HRH-10) 1/8-3.0
Is Nomex Honeycomb (HRH-10) easy to machine?
CNC route, band-knife or hot-wire-free blade cutting with sharp/serrated tools and vacuum hold-down; core crush and fuzzing are the main defects — chamfer edges before bonding.
Can Nomex Honeycomb (HRH-10) be welded?
Not weldable; cores are spliced with foaming film adhesive or potted compound and closed out with edge fillers.
Can Nomex Honeycomb (HRH-10) be formed, bent or molded?
Flat blocks are heat-formed or drape-formed to single curvature (OX grades for tighter radii); co-cure or secondary bond to prepreg/wet-layup skins with film adhesive at 120–180 °C under low pressure to avoid cell crush.
What surface finishes work on Nomex Honeycomb (HRH-10)?
Dry the core before bonding (moisture causes skin blows); pot inserts with epoxy compound, seal exposed edges to keep water out of the cells, and never leave the core exposed to UV.
Nomex Honeycomb (HRH-10) chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
