2、E, ARAMID/POLYESTER FIBERS ESB-M17H162-A NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a needled composite of aramid and polyester fiber layers. 2. APPLICATION This specification was released originally for material used as a floorpan thermal insulator on 1989

3、light trucks. The material must be applied with the aramid fibers contacting the hot floorpan surface. 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 m

4、ust conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.3 CONSTRUCTION The aramid and polyester fiber layers shall be needled together and shall not separate during shipment, handling or assembly. 3.4 COMPOSITION, by weight 3.4.1 Polyester fiber 60 +/- 5% (0.56

5、 - 2.80 tex, 50 - 75 mm staple length) 3.4.2 Aramid fiber 40 +/- 5% (Mixed size and length) 3.5 BREAKING STRENGTH, min (ASTM D 1682, Test No. 2 C-E, avg. of 5) Strongest direction 700 N Opposite direction 500 N 3.6 INTERNAL STRENGTH, min 0.20 N/cm (Avg. of 5) Test Method: Cut test specimens 250 x 50

6、 mm and separate at the aramid/polyester interface across the 50 mm width. Mount the sample on an Instron or equivalent tester and pull at a rate of 305 mm/minute for at least 150 mm of the specimen length. Results of individual test specimens shall be determined as a mean average of the high and lo

7、w values indicated on the chart. ENGINEERING MATERIAL SPECIFICATIONESB-M17H162-A Printed copies are uncontrolled Copyright 2006, Ford Global Technologies, LLC Page 2 of 3 3.7 COMPRESSION AND RECOVERY (SAE J1352, except as noted below) Dry compression, max 15% Dry recovery, min 50% Note: Cut five 305

8、 x 305 mm samples. Apply a 305 x 305 mm platen weighing 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 thickness of the pile (T1). Apply a 2.3 kg load to the center of the pile and measure again for

9、 average thickness of the pile with load (T2). Remove the load and allow pile (with platen) to recover thickness for 30 minutes. Measure again for average thickness of the pile (T3). 3.8 THERMAL CONDUCTIVITY, max (ASTM C 518) Mean temperature 24 C 0.039 Wm-1-1 93 C 0.046 Wm-1-1 3.9 DYNAMIC FLEX FATI

10、GUE (FLTM BO 012-04, Method B, 150 cycles, 13.6 kg load) This requirement is necessary only for parts where the material thickness is 13.0 mm or greater. For parts less than 13.0 mm, see paragraph 3.14.1. There shall be no separation or destruction by breakage of the fibers along the rubbing track o

11、f the simulated heel both before and after heat aging. Sample preparation: Prepare two 250 x 250 mm samples of the insulator composite. Heat age one sample for 24 h at 232 C and condition at 23 +/- 2 C for 4 h. Staple both samples adjacent to each other on a 250 x 500 mm medium to lightweight pile c

12、arpet (ESB-M3H20 or ESB-M3H30 type). Conduct the test as indicated above, making sure the simulated heel passes over both paddings in the same stroke. 3.10 WEIGHT LOSS, max 5% Test Method: Cut a sample of material weighing approximately 4 to 5 grams. Dry the sample in a mechanically convected oven f

13、or 16 h at 121 C. Remove from oven and immediately determine the weight to the nearest 0.01 g using an analytical balance (W1). Place sample in a muffle furnace for 16 h at 220 C (place sample on aluminum foil in furnace to prevent dirt pick-up). Remove from furnace and immediately reweigh to the ne

14、arest 0.01 g (W2). Calculate the % weight loss. % Weight Loss = W1- W2x 100 - W13.11 HEAT TRANSFER, max 60 C on carpet (SAE J1361, procedure C) This requirement is necessary only for parts where the material thickness is 13.0 mm or greater. For parts less than 13.0 mm, see paragraph 3.14.2. ENGINEER

Such conditions, if pre

16、sent, shall be cause for rejection. 3.13 FLAMMABILITY (ISO 3795/SAE J369) Burn Rate, max 100 mm/minute 3.14 RESTRICTIONS 3.14.1 Abrasions This material should not be used in foot traffic or load bearing areas at thicknesses less than 13.0 mm when wholly replacing a reclaimed fiber or urethane foam p

17、ad under the carpet or mat because of lower resistance to heel abrasion. Thicknesses less than 13.0 mm are acceptable when this material is added to the underside of the existing fiber or foam material. 3.14.2 Thermal To provide adequate heat protection for reclaimed fiber and urethane foam backed c

18、arpets and mats, the following restrictions must be observed: This material should not be used at thicknesses less than 13.0 mm when: . Used under urethane foam and floorpan temperatures exceed 148 C. . Used under reclaimed fiber and floorpan temperatures exceed 205 C. 5. GENERAL INFORMATION The inf

19、ormation given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 MAXIMUM OPERATING TEMPERATURE This material will withstand a continuous operating temperature of 245 C. Temperatures above this will soften and melt the polyester fibers, thereby causing the material to lose its insulating properties.
