SCOPE This specification covers a low density modified closed cell silicone foam cast directly onto silicone impregnated fiberglass ma

3、t without the use of adhesives. A second fiberglass mat may be applied to the cast foam as required. The material is self extinguishing, has low compression set and is suitable in static applications from -55 C to 260 C. 2. APPLICATION This specification was released originally for fuel tank heat sh

4、ield applications. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P

5、1111-A). 3.4 DYNAMIC MECHANICAL ANALYSIS (ASTM D 4065) Ford Motor Company, at its option, may establish a shear modulus/damping vs. temperature curves plotted for -50 to +150 C temperature range for material/parts supplied to this specification. The shear modulus and damping curves established for i

6、nitial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce shear modulus and damping curves that correspond to the reference standard when tested under the same conditions. 3.5 REQUIREMENTS FOR SILICONE FOAM 3.5.

7、1 Density, max 256 kg/m3Density shall be determined by cutting a 150 x 150 +/- 0.8 mm specimen and weighing it to +/- 0.25 grams. Thickness shall be determined with a dial micrometre having minimum pressure foot diameters of 25 mm or similar averaging procedure. Density shall be calculated as follow
