Problems solved by technology

[0002] The current industry standard (GB / T in my country, ASTM in the United States, JISZ in Japan) has the following defects in the method of testing the tensile strength and shear strength of double-sided adhesive tape: (1) It is necessary to use fixtures of different materials to test the properties of different adhesive interfaces, and to replace the fixtures high cost
(2) When testing the bonding strength of different types of directions, it is necessary to use fixtures of different structures. The cost of replacing and using fixtures is very high, and the test is inconvenient
(3) When testing the creep performance in different directions, the design difficulty and the number of fixtures are increased

Embodiment Construction

[0019] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

[0020] The multi-directional test fixture for the mechanical properties of the double-sided adhesive tape includes two modules for sticking the two sides of the double-sided adhesive tape respectively and carrying out the stress test. There are multiple force connecting parts. When the two sides of a double-sided adhesive tape under test are pasted on the pasting surfaces of the two modules, the force direction of each force-bearing connection part of one module is relative to the force-bearing direction of each force-bearing connection of the other module. The direction of force on the part. When the pasting surfaces of the two modules are pasted on both sides of a tested double-sided tape, the opposite extension lines of the force-bearing directions of the stress-bearing connecting parts of the two modules pass through the middle of the pa...

Abstract

The invention provides a mechanical property multidirectional testing fixture of a double faced adhesive tape. The mechanical property multidirectional testing fixture of the double faced adhesive tape comprises two modules which are respectively bonded with both faces of the double faced adhesive tape so as to carry out stress testing, wherein each module is provided with a bonding face and stressed connecting parts; multiple stressed connecting parts are arranged in each module; when the bonding faces of the two modules are respectively bonded with both faces of a tested double faced adhesive tape, the stress direction of each stressed connecting part of one module is respectively opposite to the stress direction of each stressed connecting part of the other module. The mechanical property multidirectional testing fixture of the double faced adhesive tape, provided by the invention, is convenient for carrying out multidirectional mechanical testing and capable of freely and conveniently switching tested medium materials without replacing the fixture.

Description

technical field [0001] The invention relates to a multidirectional test jig for the mechanical properties of a double-sided adhesive tape. Background technique [0002] The current industry standard (GB / T in my country, ASTM in the United States, JISZ in Japan) has the following defects in the method of testing the tensile strength and shear strength of double-sided adhesive tape: (1) It is necessary to use fixtures of different materials to test the properties of different adhesive interfaces, and to replace the fixtures high cost. (2) Fixtures with different structural forms are required to test the bonding strength of different types of directions. The cost of replacing and using the fixtures is very high, and the test is inconvenient. For example, if figure 1 and figure 2 Two different orientation types of fixtures are shown, where the figure 1 The force direction of the two modules 1 is perpendicular to the double-sided tape 2, figure 2 The force directions of the...
