SCOPE The material defined by this specification is a 100% nylon flock adhered to a vacuum formed or injection molded polypropylene b
3、ase by means of a non-staining adhesive. 2. APPLICATION This specification was released originally for material used on the inside surfaces of armrest stowage compartments. The flocked surface serves both as a decorative item and as a means of reducing noise due to rattling of objects in stowage com
4、partments. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.3 APPEARANCE (FLTM BI 109-01) The color and finish shall match the approved Design Cente
5、r master sample, or shall be as specified on the engineering drawing. 3.4 CONSTRUCTION 3.4.1 Flock Fiber 3.0 den (nylon, post dyed black, semi-dull), random cut, 0.030 in (0.76 mm). 3.4.2 Flocking Substrate Shall be vacuum formed or injection molded polypropylene. The thickness shall be as specified
6、 on the engineering drawing. 3.4.3 Adhesive The adhesive shall be non-staining and shall be compatible in color with the flock fiber. The adhesive shall not become soft, tacky or exhibit blistering delamination after any of the tests outlined in this specification, and shall be equal in other proper

9、shall be uniform over the entire part. Adhesion shall be such that the flock/adhesive layer may not be peeled or separated, intact, from the substrate material, as received and after the applicable ultraviolet exposure specified in paragraph 3.10, Dry Fade. Test Method: Using a scalpel or other shar
10、p implement, cut through the flock/adhesive layer to create four 1 in (25.4 mm) x 4 in (101 mm) strip samples in various areas of the part. Lift the flock/adhesive layer away from the substrate at one end of each strip so that it can be easily grabbed. Then peel the flock/adhesive strip away from th
11、e substrate by hand and record whether the strip separates cleanly or tears (adhesion stronger than flock/adhesive layer). 3.7 COMPATIBILITY Adhesives, primers or other surface treatments utilized to achieve adequate adhesion of the flock fiber to the substrate shall not adversely affect the physica
12、l properties of the substrate material. 3.8 ODOR The material must not have a disagreeable odor. 3.9 ABRASION (FLTM BN 108-02, CS-10 abrasive wheels, 500 g load) 20 cycles No wear-through of the flock fibers. 100 cycles Color and pattern in the wear area shall be compatible with the adjacent unabrad
13、ed areas. 3.10 DRY FADE (SAE J1885, 50 +/- 5% R.H., 65 +/- 2 C Black Panel) 60 Standard Fade Hours Rating 4 - 5 Rate by comparing the overall difference, or contrast, of the tested specimen and original material, with the difference represented by the AATCC Gray Scale for Evaluating Change In Color
14、(10 Step). No individual fiber or combination of fibers shall exhibit fiber degradation or color tone change.

15、how no evidence of color tone change or change in hue, in excess of a 4.5 rating of the AATCC Gray Scale for Evaluating Change In Color (10 Step). In addition, there shall be no evidence of delamination of the adhesive from the plastic substrate. 3.12 WET AND DRY CROCKING (FLTM BN 107-01) Wet 3 - 5

18、ified by the Flammability Lot Sampling Plan of FLTM BN 024-02, must be evaluated for permanency of the materials flame retardant properties per ESB-M25P3-A according to the accelerated environmental aging requirements applicable to the basic material category of this particular specification. Any ma
19、terial, portions of components, and composites defined by this specification that have been treated, modified or reformulated to conform to Flammability Lot Sampling Plan of FLTM BN 024-02, regardless of maximum burn rate, must be evaluated for both permanency of materials flame retardant properties
20、 and changes in mechanical, chemical and physical properties per ESB-M25P3-A applicable to the basic materials category of this particular specification. 3.18 FLAMMABILITY TEST PROGRAM Materials, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB-11014-AA.
