SCOPE The material defined by this specification is a fiberglass package consisting of a core bonded to a black skin of heavier density. The fibers are held toge
3、ther with phenolic resin. 2. APPLICATION This specification was released originally for material used as a sound absorber in automotive hoods. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS
4、 Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COLOR Core: Neutral Skin: Black 3.3 CONSTRUCTION 3.3.1 Core, average fiber diameter: “B“ Fibers: 0.0038 - 0.0051 mm Rotary Fibers: 0.0053 - 0.0064 mm 3.3.2 Average

9、s after loading with a 2.3 kg load. Upon removing the load, the material shall recover to at least 95% of the original thickness. Test Method: . Prepare and pile 5 samples, 305 x 305 mm x thickness. . Apply a 305 x 305 mm masonite board to the pile, weighing 0.23 kg. . Measure the height of the samp
10、les at the center of the vertical sides. The average of these readings is the initial thickness of the pile (T1). . Apply a 2.3 kg load to the center of the pile and measure again for average thickness of the pile with load (T2). T1 - T2 % Compression = - x 100 T1 ENGINEERING MATERIAL SPECIFICATION

Measure again for average thickness of the pile (T3). T3 % Recovery = - x 100 T1 3.10 RESISTANCE TO ADHESIVE SEEPAGE Shall resist penetration or
12、 seepage of ESB-M2G119, Water Dispersion, Rubber Base Adhesive, and/or ESB-M2G43 High Heat Resistant Adhesive, through more than 25% of the original material thickness. In addition, there shall be no through “spot“ bleeding in any area of the materials. Test Method: . Prepare a 305 x 305 X thickness
13、 of sample. . Uniformly apply 15 to 20 g of adhesive on the mid 305 x 305 mm area of a 305 x 381 mm phosphate coated and primed steel panel. . Place the sample on the treated surface of the panel. Roll with a 305 mm roller weighing 2.3 kg (without applying additional pressure). . Turn the panel upsi
14、de down and rest the pad on three equally spaced rods. Each rod shall have a 13 mm diameter and be securely fastened to a 305 x 305 mm masonite board. 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 three rods.* Examine t
15、he assembly for seepage after a 24 h period in the oven. * Weight must be evenly distributed to give uniform compression.

16、tion of the material when tested in the following manner: Test Method: Direct a blast of air at 45 degrees to the center portion of a representative 930 cm2 sample of material. Test in one direction, then test in a direction opposed 90 degrees to the first test (at a 45 angle). Equipment: DeVilbiss
17、JGA type 502 spray gun with an AV-15FF Fluid Tip, JGA 402FF Needle without air cap, or equivalent. Height and angle of Gun: Vertical height of gun tip shall be 75 mm from mat surface and gun shall be held at an angle of 45. Time: 20 s for each direction. Air Pressure: 0.6 - 0.8 MPa 3.12 SOUND ABSORP
