Type Designation
SAH is designated as follows:
Material, Cell Size, Density.
Example: SAH 1/8-3.0
Where:
- SAH - Showa Aramid Honeycomb.
- 1/8 - 1/8 inch cell size.
- 3.0 - 3.0 lbs/ft3 Density.
Dimensional Nomenclature
L = Ribbon Direction, or Width
W = Length, or Perpendicular to the Ribbon
T = Core Thickness, or Cell Depth
Special Cell Configuration and Processing
In addition to the hexagonal cell shapes, SAH is available in the OX cell shapes. The OX cell is an over-expanded hexagonal cell that provides a rectangular cell shapes, and provides suitable formability. SAH is also available machined to customer’s requirements, including flat pieces cut to size
Standard Dimensions
SAH is available in the following standard dimensions with the tolerances as indicated.
Cell Configuration L Direction W Direction T Maximum T Minimum Hexagonal Cell 48”±2” 96”±6” 32” 0.125” OX Cell 38”±2” 96”±6 20” 0.125” Tolerances on cut thickness are as follows:
- ±0.006” for 0.120” to 2.000” Thickness
- ±0.010” for 2.001” to 4.000” Thickness
- ±0.120” for 4.001” and over
Note:
1) T maximum and T minimum to be confirmed with Showa Sales Office.
2) Longer L and W directions are available. Please contact Showa Sales Office.
Standard Specifications
Configuration: Tolerance of the cell size will be plus or minus 10 percent of nominal cell size, that is determined by averaging measures of 10 consecutive cell length at 6 random locations. The double cell wall will be permitted providing the density is within the tolerance. The unbounded nodes will be permitted providing the minimum mechanical properties are conformable.
Density: Tolerance of the density will be plus or minus 10 percent of nominal density, that is determined by measuring on a minimum of 18 cubic inch.
