2、ATE, POLYESTER FABRIC, POLYURETHANE FOAM, WSS-M5H37-A PRISM LITE PATTERN, KNIT 1. SCOPE The material defined by this specification is a Prism Lite pattern, knit fabric, flame laminated to flame bondable polyether urethane foam. 2. APPLICATION This specification was released originally for material u

3、sed as cover material for headliners. Any other applications must be evaluated and approved by the responsible Materials Engineering activity. 3. REQUIREMENTS Materials manufactured to this Specification shall also meet the requirements contained in WSS-M15P27-F. For all test methods, no individual

4、specimen shall fall below the minimum values specified herein. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 APPEARANCE (FLTM BI 109-01) The color, pattern, an

5、d finish shall match the approved Corporate Design master sample, or shall be as specified on the engineering drawing. 3.3 ROLL GOODS QUALITY The laminate shall be uniformly bonded, and the fabric shall not delaminate from the foam during shipping, handling or in-plant processing. 3.4 COMPOSITION (A

6、STM D276) Fabric 100% Polyester Foam Polyether Polyurethane 3.5 FABRIC REQUIREMENTS The following shall be conducted on unbonded fabric 3.5.1 Fabric count (ASTM D3887) Wales 125-145 wales/10 cm Courses 130-150 courses/10 cm ENGINEERING MATERIAL SPECIFICATION WSS-M5H37-A Copyright 2013, Ford Global T

7、echnologies, LLC Page 2 of 4 3.5.2 Weight (FLTM BN 106-01) Fabric face only 80 - 110 g/m2 3.6 FOAM REQUIREMENTS The foam shall be polyether polyurethane and shall conform to ASTM D3574 USUEJ2. The following test shall be conducted on foam removed from the finished fabric/foam laminate or from surrog

8、ate foam samples when the laminate is less than 4 mm thick. 3.6.1 Tensile Strength 80 kPa min (ASTM D3574, Test E) 3.6.2 Steam Autoclave Aging (ASTM D3574, Test E and Test J2) Cut out 25 mm wide strips from the fabric/foam laminate. By hand, carefully peel or cut the foam away from the fabric taking

9、 care to minimize damage to the foam. Die cut specimens for tension test to recover the thickness. Expose them to the required autoclave aging and test. 3.6.2.1 Retained Tensile Strength 70% min of original (After 2 autoclave cycles for 10 hours total exposure) 3.7 FABRIC-FOAM LAMINATE REQUIREMENTS

10、3.7.1 Thickness Production samples specified As on the Engineering Drawing Source Approval and Master samples 2.2 0.5mm 3.7.2 Ply Adhesion, both directions 6N min (FLTM BN 151-05) The fabric shall not separate clearly from the foam surface (cohesive failure of foam required). In the case when sustai

11、ned peel cannot be obtained due to the foam tearing or breaking away from the fabric, ply adhesion shall be considered acceptable if the peak load prior to break exceeds the above minimum requirement. If the laminate is less than 4 mm thick and a numerical ply adhesion value cannot be satisfactorily

12、 obtained, ply adhesion shall be acceptable if the fabric cannot be separated cleanly from the foam. 3.7.3 Resistance to Abrasion 150 cycles (SAE J948, 500g load, CS-10 wheels) No evidence of excessive surface deterioration. The resistance to abrasion of production material shall be equal to or bett

13、er than the exhibited by the Fabric Proposal approved by the Materials Engineering Activity.
