2、DETERMINATION OF 180 DEGREE PEEL ADHESION STRENGTH Application This procedure is used to determine the peel adhesion strength of laminated rolled goods, wrapped or multi layered components. Apparatus and Materials Required Tensile Testing Machine Universal Testing Machine, Instron or equivalent capa
3、ble of using the integral method of calculation. Tape - 3M Scotch filament tape 898 or tape with equivalent tensile strength (6650 N/100 mm width) Tape - Masking tape equivalent to width of sample. Conditioning Chambers which may be required (See applicable Materials or Performance Specification) Me
4、chanical Convection Test Oven Conforming to ASTM E145 Type IIA normal oven or equivalent, 150 +/- 50 air changes per hour and capable of maintaining the specified temperature within +/- 1 C. Cold Box/Environmental Chamber Capable of maintaining the specified temperature within +/- 1 C down to - 40 C
5、. Humidity Cabinet Capable of maintaining a temperature of 38 +/- 1 C and 98 +/- 2% relative humidity. Environmental Cabinet Capable of maintaining controlled temperature and humidity conditions to +/- 1 C and +/- 2% relative humidity. Autoclave According to ASTM D3574, para 105.1. Conditioning and
6、Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/-2 C and 50 +/- 5% relative humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. Alternate test conditions required by sp
7、ecific material applications will be listed in the relevant material or material performance specification. FORD LABORATORY TEST METHOD BN 151-05 Copyright 2017, Ford Global Technologies, Inc. Page 2 of 7 Preparation of Test Specimens Number of specimens required will be identified in the material o
8、r performance specification. If the number of specimens is not specified then test 3 specimens in each direction. Roll goods sampling should be across the roll/sample width at least 10 cm from the selvedge. Test Specimen Dimensions Width: 50 mm, or as noted in spec Length: 200 mm, or long enough to
9、clamp the specimen in the machine and record separation for 100 mm, or as noted in spec. (Figure 1) Procedure 1. Manually separate the layers per the specification along the width of each test specimen for a distance of approximately 40 mm in the direction of the specimen length. (Figure 2) 2. For F
10、lexible Textiles: Adhere and staple the tape to the foam or scrim surface having at least a 25 mm overlap. (Figure 3) Flip specimen over and adhere masking tape to foam (Figure 1) For Rigid Substrates: Adhere and staple the tape to the more flexible surface having at least a 25 mm overlap. (Figure 4
11、) The tape needs to be long enough to clear the specimen end and provide an area for the grip. Typical practice is to cut the tape 80-100 mm longer than the specimen and then fold it back on its self so a 40-50 mm length of double layered tape is available for gripping. This length can be adjusted a
12、s necessary for the grips. Use the same width tape as the specimen width +/- 3 mm. Cut the tape if necessary to obtain the same width. (Figures 3 and 4) 3. Clamp separation distances should be set so that the test specimen is clamped in position without undue distortion. This should be set to allow
13、a 180 peel. The method of clamping should ensure no slippage or material damage (use rough grip faces). See Figure 5 and 6 for set up. The grip faces need to be as wide or wider than the specimens. Note: If specimen is a rigid substrate bonded to a flexible material, then separate the bonded flexibl
14、e material from the rigid substrate along the width of each test specimen such that the fixed rigid component can be held in the stationary clamp and the flexible component is in the pulling clamp. 4. Start the machine at a rate of 125 mm/minute and separate the specimen. (Different rates may be spe
15、cified in the material/performance specification). Obtain separation data for a distance of at least 100 mm. Recommend recording data for 130 mm of separation. 5. Ignore data for the first and last 10% of traverse and determine the average value (integral method preferred) as calculated per the spec
16、ification requirement. 6. Report values in Newtons per specimen width or as required in the material/performance specification. Example calculation: Load = N/mm Specimen width If required as only N then report load only FORD LABORATORY TEST METHOD BN 151-05 Copyright 2017, Ford Global Technologies,
