Description

Technical Field

[0001] This utility model relates to the field of tensile property testing technology for aramid fibers, and more specifically, to a fixture for testing the tensile properties of aramid short fibers. Background Technology

[0002] For the tensile property testing of aramid fibers with a length of 20 mm or more, the existing national standard GB / T14337 "Test Method for Tensile Properties of Chemical Fibers (Short Fibers)" can be used, and single fibers can be directly tested. However, for the tensile property testing of aramid short fibers with a length of 5 mm to 20 mm, there is currently no suitable sample preparation method for testing.

[0003] Currently, the tensile properties evaluation of aramid staple fiber is conducted using the national standard GB / T 14337 "Test Method for Tensile Properties of Chemical Fibers (Short Fibers)". This method tests the filaments before cutting, but the results do not fully reflect the mechanical properties of the aramid staple fiber after cutting. Therefore, it is necessary to explore suitable and standardized testing fixtures for aramid staple fiber tensile property testing to ensure the authenticity and accuracy of the test results and promote the improvement of aramid staple fiber product quality and efficiency. Therefore, we propose a fixture for testing the tensile properties of aramid staple fiber to address the aforementioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1-6 A fixture for testing the tensile properties of aramid short fibers includes a sample preparation platform, which includes a first base 1, a second base 2, a first fixed beam 5, a second fixed beam 6, a first sample stage 7, and a second sample stage 8.

[0034] The first fixed beam 5 is fixedly connected to the first base 1;

[0035] The second fixed beam 6 is fixedly connected to the second base 2;

[0036] The first base 1 is provided with a first sample preparation stage fixing hole 3 for installing the first sample stage 7;

[0037] The second base 2 is provided with a second sample preparation stage fixing hole 4 for installing the second sample stage 8;

[0038] Both the first sample stage 7 and the second sample stage 8 are connected to sample preparation stage positioning and fixing columns 11;

[0039] It should be noted that the sample preparation platform is divided into two parts by the first base 1 and the second base 2, leaving only fiber samples on the first sample stage 7 and the second sample stage 8. These samples are then mounted on the tensile testing instrument for tensile property testing. See [link to documentation]. Figure 6This method can accurately and effectively reflect the tensile properties of aramid staple fibers, providing valuable assistance to aramid staple fiber manufacturers in their technological research and development and production processes, and avoiding errors caused by inconsistent testing methods. By improving the fixtures for testing the tensile properties of aramid staple fibers, the operation is simplified, the testing cycle is shortened, and the standardization of aramid staple fiber tensile property testing is facilitated.

[0040] like Figure 3 As shown, the first base 1 is also provided with a first locking hole 9, and a locking screw is installed in the first locking hole 9; the second base 2 is also provided with a second locking hole 10, and a locking screw is installed in the second locking hole 10.

[0041] It should be noted that during testing, the locking screws of the first locking hole 9 and the second locking hole 10 were removed respectively, dividing the sample preparation platform into two parts. The structure is simple and the operation is convenient.

[0042] like Figure 1 , Figure 5 As shown, the sample preparation stage positioning and fixing post 11 at the first sample stage 7 is connected to the first sample preparation stage fixing hole 3 by insertion, and the sample preparation stage positioning and fixing post 11 at the second sample stage 8 is connected to the second sample preparation stage fixing hole 4 by insertion.

[0043] It should be noted that the sample preparation stage positioning and fixing post 11 facilitates the installation of the first sample preparation stage 7 and the second sample preparation stage 8 into the first sample preparation stage fixing hole 3 and the second sample preparation stage fixing hole 4, respectively.

[0044] like Figure 1 , Figure 2 , Figure 6 As shown, the first base 1, the first fixed beam 5, the first sample stage 7 and the second base 2, the second fixed beam 6 and the second sample stage 8 are symmetrically arranged, and fiber products are left on the first sample stage 7 and the second sample stage 8.

[0045] It should be noted that leaving fiber samples on the first sample stage 7 and the second sample stage 8 and installing them on the tensile testing instrument for tensile performance testing can truly, effectively and accurately reflect the tensile properties of aramid microfiber. This can provide effective assistance to aramid microfiber product manufacturers in their technology research and development and production processes, avoiding errors in results caused by inconsistent testing methods.

[0046] In use: The sample preparation platform is divided into two parts using the first base 1 and the second base 2, leaving only the fiber sample on the first sample stage 7 and the second sample stage 8. The sample is then mounted onto the tensile testing instrument for tensile property testing. (See...) Figure 6It can truly, effectively, and accurately reflect the tensile properties of aramid microfiber, providing effective assistance to aramid microfiber product manufacturers in their technology research and development and production processes, and avoiding errors in results caused by inconsistent testing methods.
