SCOPE The material defined by this specification is a napped polyester, warp knitted fabric, flame laminated to flame bondable polyether uret

3、hane foam. 2. APPLICATION This specification was released originally for material used as a cover material for headliners and sunvisors. The cover material must always be 100% bonded to the substrate material to form a composite. 3. REQUIREMENTS In addition to the requirements listed herein, the mat

4、erial when used in a unitized headliner assembly, or bonded to any substrate, shall also meet the requirements of WSS-M15P27-D, when tested as an assembly. Any other applications of this material would prior require approval of the Materials Engineering Activity. 3.0 STANDARD REQUIREMENTS FOR PRODUC

5、TION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 APPEARANCE (FLTM BI 109-01) The color, pattern, and finish shall match the approved Design Center master sample, or shall be as specified on the engi

6、neering drawing. 3.5 ROLL GOODS QUALITY The laminate shall be uniformly bonded, and the fabric shall not delaminate from the foam during shipment, handling, or in-plant processing. 3.6 COMPOSITION (ASTM D 629) Fabric 100% Polyester Foam Polyether Polyurethane ENGINEERING MATERIAL SPECIFICATIONWSS-M5

9、rethane and shall conform to ASTM D 3574 USU E J2. The following tests shall be conducted on foam removed from the finished fabric/foam laminate or from surrogate foam samples when the laminate is less than 4 mm thick. 3.8.1 Tension Test, min 80 kPa (ASTM D 3574, Test E) 3.8.2 Steam Autoclave Aging

10、(ASTM D 3574, Tests E and J2) Retained Tension, min 70% of original (After two autoclave cycles, for 10 h total exposure) Specimen preparation: Cut out 25 mm wide strips from the fabric/foam laminate. By hand, carefully peel or cut the foam away from the fabric, taking care to minimize damage to the

11、 foam. Die cut tension specimens from the foam. Allow the specimens to recover from cutting and handling. Measure and record the thickness of the specimens. Expose and test.

12、NATE REQUIREMENTS 3.9.1 Thickness, Range Production Samples As specified on engineering or pattern drawings Source Approval and 4.0 +/- 0.65 mm Master Samples 3.9.2 Ply Adhesion, both directions, min 6 N* (FLTM BN 151-05) *The fabric shall not separate cleanly from the foam surface (fabric specimen

13、shall exhibit foam particles adhered to the peeled surface). In those cases where a sustained peel cannot be obtained due to the foam tearing or breaking away completely from the fabric, ply adhesion shall be considered acceptable if the peak load prior to break exceeds the above minimum requirement

14、. If the laminate is less than 4.0 mm thick and a numerical ply adhesion value cannot be satisfactorily obtained, ply adhesion shall be acceptable if the fabric cannot be separated cleanly from the foam. 3.9.3 Resistance to Abrasion, min 150 cycles (SAE J948, 500 g load, CS-10 wheel) No evidence of

15、excessive surface deterioration. The resistance to abrasion of production material shall be equal to or better than that exhibited by the Fabric Proposal approved by the Materials Engineering Activity. 3.9.4 Resistance to Fade (SAE J1885, ISO 105-A02/ AATCC Evaluation Procedure 1) 112.8 kJ/m2Rating
