SCOPE The material def

3、ined by these specifications is made of glass fibers, bonded with a thermosetting resin and compressed into a flexible blanket. 2. APPLICATION These specifications were released originally for material used as an engine compartment heat and sound absorber. 3. REQUIREMENTS Material specification requ

4、irements 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-M99P1111-A). 3.2 DENSITY, +/- 15% (ASTM C 167, except base calcula

6、r other suitable means and report the average value. 3.3.2 Binder Content 30 +/- 5% phenol formaldehyde Test Method: Cut 1-2 g of sample into a previously ignited porcelain crucible. Condition at 102 +/- 3 C for 3 h. Record weight. Heat in a muffle furnace at 538 +/- 28 C until binder is burned off.

7、 Cool, weigh and calculate % binder on basis of conditioned weight (step #2).

9、ng manner of testing may be employed. Prepare samples per ASTM D 1682. Prepare a set of clamps, or holding devices, having the same width as the sample tested. A top clamp should be made to facilitate “pick-up“ and holding by the operator. A bottom clamp should be made with an attached hook on the b

10、ottom, or some means for adding and suspending required weights for test. The bottom clamp weight should be known so that the total accumulative suspended weight may be determined. Carefully clamp sample in holding devices. Add the required weight to the bottom clamp, then gently pick up the top cla

11、mp to allow a tensile pull on the sample. This may be repeated with additional weights to determine minimum breaking strength. 3.5 COMPRESSION AND RECOVERY 3.5.1 ESB-M12G64-A Compression, max 10% Recovery, min 95% 3.5.2 ESB-M12G65-A/ B Compression, max 5% Recovery, min 95% Test Method: Cut five 12 x

12、 12 in (305 x 305 mm) samples. (Thickness as specified on engineering drawings.) Apply a 12 x 12 in (305 x 305 mm) masonite board weighing 1/2 lb (0.23 kg) to the five plied samples. Measure the height of the pile, at the center of the vertical sides. (The average of these readings is the initial th

13、ickness of the pile (T1). ENGINEERING MATERIAL SPECIFICATION ESB-M12G64-A ESB-M12G65-A/B Copyright 2012, Ford Global Technologies, LLC Page 3 of 4 Apply a 5 lb (2.3 kg) load to the center of the pile and measure again for average thickness of the pile with load (T2). % Compression = T1 - T2 x 100 _

14、T1 Remove the load and allow pile (with board) to recover thickness for 30 min. Measure again for average thickness of the pile (T3). % Recovery = T3 x 100 _ T1 3.6 MOISTURE RESISTANCE Shall not disintegrate, delaminate, nor sustain mold growth. Test Method: Suspend a 12 x 12 x 1 in (305 x 305 x 25

15、mm) sample in a relative humidity cabinet at 38 +/- 1 C and 95 - 100% R.H. for 7 days. 3.7 AIR FLOW RESISTANCE No evidence of fiber separation nor delamination of the skin effect side. Test Method: Direct a blast of air at 45 to the center portion of a representative 1 ft2 (930 cm2) sample. Test in

16、one direction, then test at 45 in a direction opposed 90 to the first test. Height and Angle of Gun: Vertical height of gun tip shall be 3 in (76 mm) from mat surface and gun shall be held at an angle of 45. Equipment: Use a DeVilbiss JGA Type 502 spray gun with an AV-15FF Fluid Tip, JGA 402FF Needl
