A fiber tensile strength detection device

Abstract

The application discloses a fiber tensile strength detection device. The two ends of the measured fiber are fixed on the first clamping member and the second clamping member respectively. Then, the temperature inside the box is adjusted to a preset temperature by starting the temperature control assembly, and the temperature is maintained for a period of time. Then, the driving member is started to drive the first clamping member and the second clamping member to move in the direction away from each other, so as to tension the measured fiber until the measured fiber is pulled off. In this process, the tension data of the driving member is detected by the tension detection member. The fiber tensile strength is detected under different temperature conditions.

Description

Technical Field

[0001] This application relates to the field of fiber tensile strength testing technology, and in particular to a fiber tensile strength testing device. Background Technology

[0002] Fiber tensile strength refers to the maximum external force a fiber can withstand during stretching, usually measured in Newtons (N). Different types of fibers have different tensile strengths; for example, the tensile strength of carbon fiber is indicated by "T" followed by a number, with a higher number indicating higher strength. Fiber tensile strength is affected by various factors, including humidity, fiber thickness, and intermolecular forces. In tensile tests, the load-elongation curve of the fiber can be used to describe its tensile behavior.

[0003] Currently, most fiber tensile strength tests involve directly winding the two ends of the fiber onto two fixed structures in the air, and then measuring the tensile force when the two fixed structures move away from each other to reflect the fiber's tensile strength. This method is relatively complicated in terms of fiber fixation, and the temperature in the air fluctuates, leading to errors in the test results at different temperatures. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] In order to overcome the shortcomings of the prior art, this application provides a fiber tensile strength testing device.

[0006] To achieve the above objectives, this application adopts the following technical solution, including:

[0007] Box;

[0008] A first clamping member is disposed inside the box body. The first clamping member is slidably connected to the box body and is used to clamp one end of the fiber.

[0009] The second clamping member is disposed inside the box body and is slidably connected to the box body. The second clamping member is used to clamp the other end of the fiber.

[0010] A driving component is fixedly disposed inside the housing, and the driving component is used to drive the first clamping component and the second clamping component to move toward each other or away from each other.

[0011] A tension detection element is disposed on the drive element. The tension detection element is used to detect the tension between the drive element and the first clamping element, and the tension detection element is also used to detect the tension between the drive element and the second clamping element.

[0012] A temperature control component is fixedly installed on the enclosure and is used to control the temperature inside the enclosure.

[0013] A temperature sensor is fixedly installed inside the enclosure and is used to detect the temperature inside the enclosure.

[0014] The advantage of this application is that it provides a fiber tensile strength testing device. First, the two ends of the fiber to be tested are fixed to a first clamping member and a second clamping member, respectively. Then, a temperature control component is activated to adjust the interior of the chamber to a preset temperature and maintain it for a period of time. Next, a driving component is activated to move the first and second clamping members in a direction away from each other, thereby tightening the fiber to be tested until it breaks. During this process, the tensile force data of the driving component is detected by a tensile force detection component. This enables the testing of fiber tensile strength under different temperature conditions. Attached Figure Description

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-2 As shown, in one embodiment of this application, the fiber tensile strength testing device includes: a housing 11, a first clamping member 12, a second clamping member 13, a driving member 14, a tensile force testing member 15, a temperature control component 16, and a temperature sensor 17.

[0033] The first clamping member 12 is disposed inside the box body 11 and is slidably connected to the box body 11. The first clamping member 12 is used to clamp one end of the fiber.

[0034] The second clamping member 13 is disposed inside the box body 11 and is slidably connected to the box body 11. The second clamping member 13 is used to clamp the other end of the fiber.

[0035] The driving component 14 is fixedly disposed inside the housing 11, and the driving component 14 is used to drive the first clamping component 12 and the second clamping component 13 to move towards each other or away from each other.

[0036] The tension detection element 15 is disposed on the drive element 14. The tension detection element 15 is used to detect the tension between the drive element 14 and the first clamping element 12.

[0038] The temperature sensor 17 is fixedly installed inside the housing 11, and the temperature sensor 17 is used to detect the temperature inside the housing 11.

[0039] Specifically, the frictional resistance between the first clamping member 12 and the second clamping member 13 and the housing 11 can be reduced by activating the drive member 14 in an unloaded state to move the first clamping member 12 and the second clamping member 13. At this time, the detection value of the tension detection member 15 is the frictional resistance value between the first clamping member 12 and the second clamping member 13 and the housing 11.

[0040] In this embodiment, the two ends of the fiber to be tested are first fixed to the first clamping member 12 and the second clamping member 13, respectively. Then, the temperature control component 16 is activated to adjust the interior of the chamber 11 to a preset temperature and maintain it for a period of time. Next, the driving member 14 is activated to move the first clamping member 12 and the second clamping member 13 in a direction away from each other, thereby tightening the fiber to be tested until it breaks. During this process, the tension data of the driving member 14 is detected by the tension detection member 15. This allows for the detection of fiber tensile strength under different temperature conditions.

[0049] like Figure 3-6 As shown, in one embodiment of this application, the structure of the first clamping member 12 is the same as the structure of the second clamping member 13.

[0056] The guide plate 122a is T-shaped and is inserted into the first limiting groove 121a. The guide plate 122a is fixedly connected to the first positioning block 121 by bolts.

[0057] The locking block 122b is configured as a plurality of blocks, the number of which is the same as the number of locking slots 121b, and one locking block 122b is inserted into one locking slot 121b.

[0058] Specifically, the first clamping member 12 is horizontally displaced by a certain distance to determine the placement position of the second clamping member 13.

[0059] In this embodiment, one end of the fiber is first placed in the first limiting groove 121a, and then a guide plate 122a with multiple locking blocks 122b is inserted into the first limiting groove 121a. At this time, each locking block 122b will be inserted into a locking groove 121b, thereby fixing one end of the fiber.

[0067] In this embodiment, the fiber is stretched until it breaks by simultaneously activating the first electric actuator 141 and the second electric actuator 142 or by activating one of the first electric actuator 141 and the second electric actuator 142 individually. Then, the tension is monitored during the fiber breaking process by the first tension sensor 151 and the second tension sensor 152.
