Hexcel HexWeb HRH-10 product data sheet (inch version), mechanical properties table, tested per AMS-STD-401 at 0.500 in core thickness. Designation is material, cell size in inches, nominal density in lb/ft³. Density tolerance is ±10 % measured on at least 100 in³ of core. Other cell sizes (for example 3/16) and densities are in the same table. kg/m³ converted at 16.02 per lb/ft³.
Notes from the guide
- One family. HRH-10 values are typical numbers from one datasheet.
- Not a substitution table. The SRM names the core.
