1、Designation: D3167 10Standard Test Method forFloating Roller Peel Resistance of Adhesives1This standard is issued under the fixed designation D3167; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A numbe
2、r in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe purpose of this test method is to provide for the determination of the metal-to-metal peelstrength of adhesives by a method that will pr
3、ovide good reproducibility at low-, as well as athighstrength levels and yet allow for a simple method of test specimen preparation and testing.The accuracy of the results of strength tests of adhesive bonds will depend on the conditions underwhich the bonding process is carried out. Unless otherwis
4、e agreed upon between the manufacturer andthe purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive. In orderto ensure that complete information is available to the individual conducting the tests, themanufacturer of the adhesive shall furnish numerical values and
5、 other specific information for each ofthe following variables:(1) Procedure for preparation of the surfaces prior to application of the adhesive, the cleaning anddrying of metal surfaces, and special surface treatments such as sanding, which are not specificallylimited by the pertinent test method.
6、(2) Complete mixing directions for the adhesive.(3) Conditions for application of the adhesive, including the rate of spread or thickness of film,number of coats to be applied whether to be applied to one or both surfaces, and the conditions ofdrying where more than one coat is required.(4) Assembly
7、 conditions before application of pressure, including the room temperature and lengthof time.(5) Curing conditions, including the amount of pressure to be applied, the length of time underpressure, and the temperature of the assembly when under pressure. It should be stated whether thistemperature i
8、s that of the glue line, or of the atmosphere at which the assembly is to be maintained.(6) Conditioning procedure before testing, unless a standard procedure is specified, including thelength of time, temperature, and relative humidity.Arange may be prescribed for any variable by the manufacturer o
9、f the adhesive, if it can be assumedby the test operator that any arbitrarily chosen value within such a range or any combination of suchvalues for several variables will be acceptable to both the manufacturer and the purchaser of theadhesive.1. Scope1.1 This test method covers the determination of
10、the relativepeel resistance of adhesive bonds between one rigid adherendand one flexible adherend when tested under specified condi-tions of preparation and testing.1.2 A variation in thickness of the adherends will generallyinfluence the test values. For this reason, the thickness of thesheets used
11、 to make the test specimens shall be specified in thematerial specification. When no thickness is specified, theflexible adherend shall be 0.63 mm (0.025 in.) thick and therigid adherend shall be 1.63 mm (0.064 in.) thick.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives

Terminology3.1 DefinitionsMany of the terms used in this test methodare defined in Terminology D907.4. Summary of Test Method4.1 This test method consists of testing lamina
16、ted or bondedadherends, where one adherend is made to be rigid and theother adherend is made to be flexible, by peeling of the flexibleadherend from the rigid adherend at a controlled angle of peelusing the test fixture shown in Fig. 1.5. Significance and Use5.1 Use this test method for acceptance a
17、nd process controltesting. This test method may be used as an alternative to TestMethod D1781 when that facility is not available. This testmethod is considered more severe since the angle of peel isgreater.6. Apparatus6.1 Testing Machine, conforming to the requirements ofPractices E4. Select a test
18、ing machine that is autographic withchart capability, that reads and records in millimetres (inches)of separation as one coordinate and applied load as the othercoordinate, the applied load accurate to within 61 %. Addi-tional capabilities of the machine are a crosshead rate of 152mm/min (6 in./min)
19、, with self-aligning grips to hold thespecimen, and where the breaking load of the specimens fallsbetween 15 and 85 % of the full-scale machine capacity. Thegrips need to engage the outer 25.4 mm (1 in.) of the flexibleadherend firmly and when the load is applied, the direction ofthe applied pull ne

Sample Preparation7.1 Laminated test panels (see Fig. 2) consist of twoadherends properly prepared and bo
22、nded together in accor-dance with the adhesive manufacturers recommendations. Atleast 30.5 mm of the flexible member should be masked withPTFE tape release film, or by equivalent means, to preventadhesion of rigid member in the area shaded in Fig. 2. This willhelp enable the flexible member to be mo
23、re easily bent inaccordance with the picture of the test specimen in Fig. 2,asdescribed in 7.3.7.2 Unless otherwise specified, use clad aluminum alloyconforming to the specification for aluminum-alloy sheet andplate (Specification B209) Alloy 2024-T3.7.3 Cut the bonded panels into 12.7-mm (0.5-in.)
24、wide testspecimens (see Fig. 2) by a means that is not deleterious to thebond. The use of edge members depends upon the desire tomeasure peel strengths in this area. The method of cutting testspecimens is controlled by adherend and adhesive composi-tions and the accuracy desired. Shearing, milling,
25、and band-saws can all be used successfully. Bend the unbonded end ofthe flexible adherend, perpendicular to the rigid adherend,peeling the flexible adherend away from the rigid adherend forat least 30.5 mm (see Fig. 2). Select two specimens for eachtemperature tested from each of three bonded panels
26、.NOTE 1Direct comparison of different adhesives may be made onlywhen specimen construction and test conditions are identical.NOTE 2Within the limitations imposed by 7.3, other specimen widthsmay be used, provided the test machine grip and peel test fixtures are ofample width to apply the load unifor
27、mly across the width of theadherends.NOTE 3Direct comparison of different adhesives may be made onlywhen the angle of peel is identical. The operator must ascertain that theflexible adherend is bending over the mandrel and not at some irregularangle.8. Test Method8.1 Insert the test specimen into th
28、e peel test fixture asshown in Fig. 1, with the unbonded end of the flexibleadherend gripped in the test machine jaw. Peel the specimen at152-mm/min (6-in./min) bond separation rate by applying theload at a constant head speed of 152 mm/min. If the rigidadherend bends or is distorted during the test
29、, it is recom-mended that the specimen be redesigned with a backup rigidadherend stiff enough to ensure even peel.8.2 During the peel test, make an autographic recording ofload versus head movement (load versus distance peeled).8.3 Record the load over at least a 76-mm (3-in.) length ofthe bond line
30、, disregarding the first 25.4 mm (1 in.) of peel.9. Calculation9.1 Determine from the autographic curve, or at least 76.2mm (3 in.) of peeling (disregarding the first 25.4 mm (1 in.),the average peeling load in pounds-force per inch (or kilone-wtons per metre) of the specimen width required to separ
31、ate theadherends. It is preferred that the average load be determinedfrom the curve by means of a planimeter.NOTE 4In case a planimeter is not used, the average may becalculated as the average of load readings taken at fixed increments ofcrosshead motion. For example, the load may be recorded at eac
32、h12.7-mm (12-in.) interval of crosshead motion (discarding the first 25.4mm (1 in.) until at least six readings have been attained.10.
