2、T, GLASS FIBER, SOUND ABSORPTION ESB-M12G63-A HIGH BINDER CONTENT NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a fine fibered, flexible, resilient blanket of fibrous glass bonded with a thermosetting resin to provide dimensional stability and good handling pro

3、perties. 2. APPLICATION This specification was released originally for material used as a sound absorber. 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 producer

4、s must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COLOR Black or neutral 3.3 DENSITY, +/- 15% tolerance 1.25 lb/ft3 (20.0 kg/m3) (ASTM D 167, except base calculations on nominal thickness as specified on engineering drawing) 3.4 THICKNESS As specifie

5、d on engineering drawing with the following tolerances: Under 1.0 in (25 mm) +1/8 in (3.2 mm) -1/16 in (1.6 mm) 1.0 in (25 mm) and over +1/4 in (6.4 mm) -1/8 in (3.2 mm) 3.5 CONSTRUCTION 3.5.1 Fiber Diameter 0.00023 +/- 0.00002 in (0.0058 +/- 0.0005 mm) Test Method: Measure the diameter of 10 fibers

6、 using a calibrated microscope or other suitable means. ENGINEERING MATERIAL SPECIFICATION ESB-M12G63-A Copyright 2012, Ford Global Technologies, LLC Page 2 of 3 3.5.2 Binder Content 18 +/- 3% phenol formaldehyde Test Method: Cut 1 - 2 g of sample into a previously ignited porcelain crucible. Condit

7、ion at 102 +/- 3 C to constant weight and record weight. Heat in muffle furnace at 538 +/- 28 C until binder is burned off. Cool, weigh and calculate % binder on basis of conditioned weight. 3.6 BREAKING STRENGTH, min (ASTM D 1682, Grab Method) 1 in (25 mm) min thickness 15 lb (67 N) For thicknesses

8、 less than 1 in (25 mm), combine two or more samples to provide a minimum thickness of 1 in (25 mm). Modified Test Method: If a test machine is not available as in ASTM D 1682, or if an existing machine is not calibrated for testing this material, the following manner of testing may be employed. Pre

9、pare samples as outlined in 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 bottom, or some means for addin

10、g 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 clamp to allow a tensile pull on

11、the sample. This may be repeated with additional weights to determine minimum breaking strength. 3.7 COMPRESSION AND RECOVERY 3.7.1 Compression, max 10% 3.7.2 Recovery, min 95% Test Method: Prepare and pile five 12 x 12 in (305 x 305 mm) x thickness of samples. Apply a 12 x 12 in (305 x 305 mm) maso

12、nite board to the pile, weighing 1/2 lb (0.23 kg). Measure the height of the pile, at the center of the vertical sides. (The average of these readings is the initial thickness of the pile (T1). Apply a 5 lb (2.3 kg) load to the center of the pile and measure again for average thickness of the pile w

13、ith load (T2). % Compression = T1 - T2 x 100 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 ENGINEERING MATERIAL SPECIFICATION ESB-M12G63-A Copyright 2012, Ford Global Technologies, LLC Pa

14、ge 3 of 3 3.8 RESISTANCE TO ADHESIVE SEEPAGE Shall resist penetration or seepage of ESB-M2G119, Water Dispersion - Rubber Base Adhesive, and/or ESB-M2G43, High Heat Resistant Adhesive, through more than 25% of the original thickness. In addition, there shall be no through “spot“ bleeding in any area

15、 of the material. Test Method: Prepare a 12 x 12 in (305 x 305 mm) x thickness of sample. Uniformly apply 15 - 20 g of ESB-M2G119 or ESB-M2G43 on the mid 12 x 12 in (305 x 305 mm) area of a 12 x 15 in (305 x 381 mm) phosphate coated and primed steel panel. Place the sample on the treated surface of

16、the panel, then roll with a 12 in (305 mm) roller weighing 5 lb (2.3 kg) (without applying additional pressure). Turn the panel upside down and rest the pad on 3 equally spaced rods. Each rod shall have a 1/2 in (13 mm) diameter and be securely fastened to a 12 x 12 in (305 x 305 mm) masonite board.

17、 Place the assembly in oven at 102 +/- 3 C. Load the test panel with sufficient weight to compress the pad 50% over each of the 3 rods. Weight must be evenly distributed to give uniform compression. Examine the assembly for seepage after a 24 h period in the oven. 3.9 SOUND ABSORPTION, min 50% (Aver

18、age 500 - 5000 cps (Hz) as tested by the Radio Section, Electrical Department, Ford Car Product Engineering Department; based on 1 in (25 mm) nominal thickness). 3.10 QUALITY The material when molded into a finished part, shall be uniform in color and have a non-fuzzy surface. The exposed surface shall be relatively free of white caps and shall be able to withstand the air erosion requirements established by the responsible product engineering office. The formed part shall be free of uncured areas and binder spots and there shall be no cracks or shingling effect on the finished skin surface.
