REQUIREMENTS: 3.1 Preproduction sample: When specified in the contract or order (see 4.4.2 and 6.2), preproduction samples of
15、nylon paper core material of designated density, cell size dimension, resin bond, and core cell configuration shall be manufactured using the methods and processes proposed for the production lot. These samples are for the purpose of determining that the manufacturers production methods and processe
16、s will produce core material that will meet the requirements of this specification. These samples shall be inspected as specified in Section 4 and shall be submitted as directed by the procuring activity for examination and approval.3.1.1 Material and property control: Prior to production, material
17、and property controls shall be established for the core cell size, type and quantity of the stabilizing resin, adhesive, and bonding methods. The control shall be continued until the application of resin and adhesive, assembly of the materials and curing of the adhesive practices have been establish
18、ed to produce core materials conforming to this specification. When processing practices have been so established, the production shall not be changed without demonstrating to the satisfaction of the procuring activity that the change does not adversely affect the quality of the core material.AMS-C-

20、pplicable specifications and shall be as specified herein. Materials, which are not covered by applicable specifications, or which are not specifically described herein, shall be subjected to the approval of the procuring activity.3.2.1 Paper: The fiber paper shall be composed of an aromatic polyami
21、de polymer (nylon) in the form of short fibers (floc), bonded together with small fibrous binder particles (fibrids) of the same material, and shall contain no extraneous diluents. The paper shall not be perforated.3.2.2 Resin: The resin system used to coat the paper, or for node bonding, shall be r
22、esistant to mildew and shall not be corrosive to metals. Node bonding shall be accomplished with the same resin used for coating, or with a compatible resin adhesive.3.3 Configuration: The core material shall consist of thin nylon paper base sheets bonded together to form cells approximately hexagon
23、al in shape (See Figure 1).3.4 Sizes: The material shall be furnished in blocks or slices, as specified by the procuring activity. The dimensions and dimensional tolerances for the blocks or slices shall be as specified by the procuring activity.3.5 Cure: The honeycomb core material shall be fully c
24、ured. When specified, the material may be furnished in a partially cured state to afford better conformability when used in curved sections. In this case the material shall be fully cured in accordance with the manufacturers instructions prior to testing.3.6 Bond or slicing test: The node bonds of t
