AHN4120 ARAMID FIBER/PHENOLIC COATED HONEYCOMB

AHN 4120 is an Aerospace Grade Nomex^® Honeycomb which exhibits high strength and toughness in a small cell, low density, non-metallic honeycomb.

It is particularly noted for its corrosion resistance. This material is fire resistant and is typically used in transport aircraft construction where low O.S.U., smoke, and toxicity characteristics are a necessity.

This material also exhibits good thermal insulation properties and also has good dialectic properties. This honeycomb is easily machined, formed, and shaped and well suited to adhesive bonding.

PRODUCT DESIGNATION

A wide variety of cell sizes, web gauges, resin coating weights, and cell shapes are available. Strength characteristics are illustrated below. The products are designated as follows:

SPECIFICATIONS
AHN 4120 honeycomb meets most commercial specifications. These include the strength requirements of BMS 8-124, DMS 1974, AMS 3711, and MIL-C-81986. Because of the large number of specifications and frequent revisions, we must be advised as to your requirements when we quote. If no specification is stated, we will certify to our Product Data sheet.

AVAILABILITY
AHN 4120 is supplied in standard sheet sizes of 48”L by 96”W for hexagonal shaped cells and 38”L by 96”W for over-expanded shaped cells. The sheet thicknesses can be custom cut from .060 inches up depending on customer’s requirement, material cell size and density.

Special sheet sizes, both larger and smaller are available on a special order basis. Because of the special size, a minimum order may be required.

SHEET SIZE TOLERANCES
Length (W) & Width (L) = -0 +4 inches
Thickness (T) = +/- .006 up to 2.00 inches
= .010 to 4.00 inches
= .060 above 4.00 inches

Closer tolerances are possible and may carry a premium price.

All tests are per MIL–STD–401B, core thickness of .500″ (for core (T) of .270 increase shear strengths by 14%). Min indicates a specification minimum value. Typ indicates averages of typical production test results, actual results may be lower.
