SCOPE The material defined by this specification is a bonded composite of an aramid/polyester heat resistant scrim, aluminum foil and a needled polye

3、ster batt. 2. APPLICATION This specification was released originally for material used as a thermal insulator under carpet or mat assemblies in light trucks. The material must be applied with the aramid/polyester heat resistant scrim contacting the hot floorpan surface. 3. REQUIREMENTS Material spec

4、ification requirements 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). 3.3 CONSTRUCTION The polyester fiber la

Apply a 305 x 305 mm platen weighing 0.23 kg to the five plied samples. Then apply a 4.6 kg load to the center of the pile for 5 minute

10、s to remove any buckling in the aluminum foil. Remove the 4.6 kg load and allow the samples to recover for 24 h. Measure the height of the pile at the center of the vertical sides. The average of these four readings is the initial thickness of the pile (T1). Apply a 2.3 kg load to the center of the

11、pile and immediately measure again for 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 DYNAMIC FLEX FATIGUE (FLTM 112-04, Method B, 150 cycles, 267 N load) There

12、shall be no separation or destruction by breakage of the fibers along the rubbing track of the simulated heel both before and after heat aging. Sample preparation: Prepare two 250 x 250 mm samples of the insulator. Heat age one sample for 24 h at 230 C and condition at 23 +/- 2 C for 4 h. Staple bot

13、h samples adjacent each other on a 250 x 500 mm medium to lightweight pile carpet (heat resistant scrim side facing down). Conduct the test as indicated above, making sure the simulated heel passes over both paddings in the same stroke. ENGINEERING MATERIAL SPECIFICATIONWSB-M17H165-A Printed copies
