SCOPE The material defined by these specifications is a resin bonded fiber batt of good quality and uniform construction. 2. APPLICATION These specifications were released orig

3、inally for material used as sound absorption batts for the tray, cowl, side and roof panels of car bodies. 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 produce

4、rs must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 COMPOSITION AND CONSTRUCTION These materials shall consist of a mixture of cotton and synthetic garnetted fibers in either a parallel or random orientation. The fibers shall be firmly bonded with a p

5、henolformaldehyde resin (10 - 25% by weight). 3.3 RESISTANCE TO ADHESIVE SEEPAGE Shall resist penetration or seepage of ESB-M2G56 and/or ESB-M2G43 Adhesives (Rubber Base), through more than 50% of the thickness of the material. In addition, there shall be no through “spot“ bleeding at any area of th

6、e material. Test Procedure . Prepare a 12 x 12 in (300 x 300 mm) x thickness of sample. . Apply 15 - 20 g of ESB-M2G56 and/or ESB-M2G43 on the mid 12 x 12 in (300 x 300 mm) area of a sheet steel panel, spreading uniformly over the surface. The panel used should be 12 x 15 in (300 x 380 mm) or a size

7、 which will permit support of the two lengthwise ends over a frame or rack. . Place the sample on the treated surface of the panel, then roll with a roller, 12 in (300 mm) long and weighing 5 lb (2.3 kg) (without applying additional pressure).

Allow adhesive to set for 24 h at 23 +/- 2 C. . Determine % seepage. 3.4 SOUND ABSORPTION Sound shall be absorbed as spec

9、ified on engineering drawings. 3.5 AIR FLOW RESISTANCE No evidence of fiber separation and/or delamination. Test Method: Direct a blast of air at 45 to the center portion of a representative 1 ft2 (930 cm2) sample of material. Test in one direction, then test at 45 in a direction opposed 90 to the f

10、irst test. Equipment: use of DeVilbiss 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 3 in (76 mm) from mat surface and gun shall be held at an angle of 45. Time: 20 s minimum for each di

11、rection. Air Pressure: 90 - 100 psi (620 - 690 kPa) 3.6 COMPRESSION AND RECOVERY (FLTM BN 015-02) Shall not compress more than 70% of the original thickness, after loading with 75 lb (34 kg). Upon removing load, the material shall recover at least 65% of the compressed distance. 3.7 BREAKING STRENGT

13、idual asphalt and other contaminants which might cause padding to trim cover material contact stains, bondline, or sewline stains. 3.9 ESB-M17H84-B FLAMMABILITY REQUIREMENT 3.9.1 Flammability In order to comply with Federal Motor Vehicle Safety Standard No. 302, the materials, portions of components

14、, and composites shall not burn, or transmit a flame across its surface, at a rate of more than 4 in (101 mm) per min. To demonstrate compliance, the sample size and method of testing shall be in accordance with FLTM BN 024-02. 3.9.2 Performance - Environmental Aging All materials, portions of compo

15、nents, and composites defined by the specification that have not been treated, modified or reformulated and exceed a max burn rate of 3.0 in (76 mm) per min as specified by the Flammability Lot Sampling Plan of FLTM BN 024-02, must be evaluated for permanency of the materials flame retardant propert

16、ies per ESB-M25P3-A according to the accelerated environmental aging requirements applicable to the basic material category of this particular specification. Any material, portions of components, and composites defined by this specification that have been treated, modified or reformulated to conform

17、 to Flammability Lot Sampling Plan of FLTM BN 024-02, regardless of max burn rate, must be evaluated for both permanency of materials flame retardant properties and changes in mechanical, chemical and physical properties per ESB-M25P3-A applicable to the basic materials category of this particular specification. 3.9.3 Flammability Test Program Materials, portions of components, and composites governed by this specification must also comply with the requirements of ES-D3AB11014-AA.
