Abstract
Description
Technical Field
[0001] This invention belongs to the field of carbon fiber multifilament mechanical preparation technology, specifically, it relates to a device that can simultaneously prepare both national standard and American standard Noel ring samples. Background Technology
[0002] Today, carbon fiber is one of the most important reinforcements in advanced composite materials, and its interlaminar shear strength is crucial for achieving the structural performance of composite materials. Carbon fiber interlaminar shear strength refers to the stress generated within the material as a resistance to relative displacement between adjacent layers after lamination of different fiber composite products; it is the ultimate stress of the laminate under interlaminar shear stress. The presence of interlaminar stress easily leads to delamination failure, which severely reduces the stiffness and strength of composite laminates. Therefore, interlaminar issues such as interlaminar stress and interlaminar shear strength are important considerations in composite material design.
[0003] Carbon fiber composites have the advantages of being lightweight, high-strength, and having a high elastic modulus. They have made a significant contribution to improving the performance of energy (wind power) and weaponry, and are widely used in the manufacture of wind turbine blades, aircraft fuselages and engines, missile casings, and other major defense and industrial fields. They have become one of the essential new materials for modern development.
[0004] In industrial production of carbon fibers, the interlaminar shear strength of the carbon fibers must be tested. The interlaminar shear strength and other performance parameters of the fibers ultimately determine the performance of the composite material.
[0005] Currently, there are two recognized testing methods for carbon fiber Noir rings: the Chinese national standard and the American standard. Each time an experiment is conducted, two sets of tooling are required, one for the Chinese national standard and one for the American standard. After the Chinese national standard experiment is completed, the Chinese national standard tooling is disassembled and then the American standard tooling is installed. Disassembly and installation are cumbersome, and frequent disassembly can cause significant damage to the equipment. Each set of tooling is heavy, labor-intensive, and time-consuming.
[0006] In view of this, this utility model is proposed. Utility Model Content

By integrating the national standard Noer ring liner and the American standard Noer ring liner on a rotating shaft, the problem of frequent replacement of different tooling for carbon fiber and the cumbersome disassembly and installation is solved, thereby improving work efficiency.
[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0020] A gap is formed between two adjacent Norring caps for installing a national standard Norring liner (1) or an American standard Norring liner (2).
[0021] Furthermore, the two ends of the national standard Noer ring bushing are respectively fitted with two Noer ring caps;
[0022] The two ends of the American Standard Noir ring liner are respectively fitted to two Noir ring caps.
[0023] Furthermore, the national standard Nor ring bushing and two adjacent Nor ring caps form an annular first groove;
[0024] The American Standard Noir ring liner and two adjacent Noir ring caps form an annular second groove.
[0025] Furthermore, it also includes fasteners;
[0026] Each of the Norring caps has a through hole;
[0027] The fasteners pass through the through holes in sequence to connect the various Norring caps together.
[0028] Furthermore, a limiting part is provided at one end of the rotating shaft for fixing the Noor ring cap provided at that end.

[0046] Carbon fiber composites have the advantages of being lightweight, high-strength, and having a high elastic modulus. They have made a significant contribution to improving the performance of energy (wind power) and weaponry, and are widely used in the manufacture of wind turbine blades, aircraft fuselages and engines, missile casings, and other major defense and industrial fields. They have become one of the essential new materials for the development of modern strategic weapons.
[0047] In industrial carbon fiber production, the interlaminar shear strength of the carbon fibers must be tested. The interlaminar shear strength and other performance parameters of the fibers ultimately determine the properties of the composite material. Currently, there are two recognized testing methods for carbon fiber nor rings: Chinese national standards and American standards.
[0048] Specifically, in the US standard, the span-to-thickness ratio (L / h) of the sample ring is typically between 4 and 6, with L / h = 5 generally recommended. The span can be adjusted according to the material stiffness. The common thickness is 3.2 mm, and the width is 6.4 mm. The Chinese national standard specifies a span-to-thickness ratio of L / h = 5 and also has clear requirements for the length, width, and thickness of the sample, such as a length (L) of 15 mm ± 1 mm, a width (b) of 10 mm ± 0.5 mm, and a thickness (h) of 2 mm ± 0.2 mm. In comparison, the US standard offers more flexibility in sample size selection, while the Chinese national standard provides more specific and detailed specifications for sample dimensions.
[0049] Currently, each experiment requires preparing two sets of tooling, one for Chinese national standards and the other for American standards. After the Chinese national standard experiment, the tooling is disassembled and the American standard tooling is installed. This disassembly and installation process is cumbersome, frequent disassembly causes significant damage to the equipment, and each set of tooling is heavy, labor-intensive, and time-consuming. To solve these problems, this application provides a device that can simultaneously prepare both Chinese national standard and American standard Noel ring samples.
[0050] like Figures 1 to 2 As shown, the apparatus of this invention for simultaneously preparing standard and American standard Knoll ring samples includes a standard Knoll ring liner 1, an American standard Knoll ring liner 2, and a rotating shaft 3. The standard Knoll ring liner 1 has an annular first winding portion 11 for winding carbon fiber, and the American standard Knoll ring liner 2 has an annular second winding portion 21 for winding carbon fiber. The width of the first winding portion 11 is greater than the width of the second winding portion 21 for winding carbon fiber. The rotating shaft 3 has a certain axial extension length, and both the standard Knoll ring liner 1 and the American standard Knoll ring liner 2 are mounted on the rotating shaft 3.
[0051] By integrating the GB / T 1 and ASME 2 Noir rings onto a single rotating shaft 3, carbon fiber can be wound onto either the GB / T 1 or ASME 2 rings, depending on the specific requirements. Alternatively, carbon fiber can be wound onto both rings simultaneously. This reduces the inconvenience to operators caused by repeatedly switching between the equipment for different GB / T and ASME standard samples, improves work efficiency, reduces labor intensity, shortens overall experimental time, lowers equipment costs, and reduces instrument failure rates due to frequent disassembly and reassembly.
[0052] In this embodiment, the rotating shaft 3 is a cylindrical rotating shaft, and the American standard Noir ring liner 2, the national standard Noir ring liner 1 and the rotating shaft 3 are coaxially arranged, which can improve the overall stability.
[0053] In this embodiment, both the American Standard Noir ring 2 and the GB Noir ring 1 are fixedly mounted on the rotating shaft 3. When the rotating shaft 3 rotates, the American Standard Noir ring 2 and the GB Noir ring 1 can rotate together. The rotating shaft 3 is connected to the machine tool, and the carbon fiber is wound into the first winding part 11 or the second winding part 21 by rotating the rotating shaft 3.
[0054] In this embodiment, the device that can simultaneously prepare both national standard and American standard Norr ring samples also includes Norr ring caps 4. Multiple Norr ring caps 4 are provided, and each Norr ring cap 4 is spaced apart along the axial direction of the rotation axis 3. A gap is formed between two adjacent Norr ring caps 4 for installing the national standard Norr ring liner 1 or the American standard Norr ring liner 2.
[0055] In this embodiment, multiple GB / T Knorr ring inserts 1 and ASME Knorr ring inserts 2 are provided, and the GB / T Knorr ring inserts 1 and ASME Knorr ring inserts 2 are alternately arranged along the axial direction of the rotation axis 3. Multiple GB / T Knorr ring inserts 1 and ASME Knorr ring inserts 2 can be provided, thereby achieving the purpose of simultaneously preparing multiple sample rings and improving winding efficiency.
[0056] In this embodiment, specifically, each Noor ring cap 4 is arranged sequentially along the axial direction of the rotation axis 3. A national standard Noor ring bushing 1 is set between the first Noor ring cap 4 and the second Noor ring cap 4, and an American standard Noor ring bushing 2 is set between the second Noor ring cap 4 and the third Noor ring cap 4. This arrangement is carried out sequentially.
[0057] In this embodiment, both the ASME Noir ring liner 2 and the GB Noir ring liner 1 are annular structures, and the circular holes at the center of the ASME Noir ring liner 2 and the GB Noir ring liner 1 are just enough for the rotating shaft 3 to pass through. The difference between the ASME Noir ring liner 2 and the GB Noir ring liner 1 is that their diameters are different; the GB Noir ring liner 1 has a diameter of 144 mm, while the ASME Noir ring liner 2 has a diameter of 150 mm.
[0058] In this embodiment, the two ends of the national standard Knoll ring liner 1 are respectively fitted with two Knoll ring caps 4, and the two ends of the American standard Knoll ring liner 2 are respectively fitted with two Knoll ring caps 4. The national standard Knoll ring liner 1, the Knoll ring caps 4, and the American standard Knoll ring liner 2 are connected together. When the rotating shaft 3 rotates, the national standard Knoll ring liner 1 and the American standard Knoll ring liner 2 can rotate synchronously. When the national standard Knoll ring liner 1 and the American standard Knoll ring liner 2 are wound with carbon fiber, the uniformity of the wound carbon fiber can be ensured. This also allows the entire device to be integrated, making the overall structure more compact.
[0059] In this embodiment, the national standard Knoll ring liner 1 and two adjacent Knoll ring caps 4 form a first annular groove; the American standard Knoll ring liner 2 and two adjacent Knoll ring caps 4 form a second annular groove. When the rotating shaft 3 rotates, carbon fiber can be wound around the first groove formed by the two Knoll ring caps 4 and the national standard Knoll ring liner 1. The wound carbon fiber can then be subjected to national standard testing. When the rotating shaft 3 rotates, carbon fiber can be wound around the second groove formed by the two Knoll ring caps 4 and the American standard Knoll ring liner 2. The wound carbon fiber can then be subjected to American standard testing.
[0060] In this embodiment, each Noor ring cap 4 is detachably connected. The detachable design improves the convenience of installation and disassembly. At the same time, the number of Noor ring caps 4 can be increased or decreased at will according to actual needs, thereby adjusting the number of national standard Noor ring liners 1 and American standard Noor ring liners 2.
[0061] Specifically, each Nol ring cap 4 is provided with a through hole 6, and the Nol ring caps 4 are connected together by fasteners 5. For example, the Nol ring caps 4 are connected together by bolts. Moreover, the width of the carbon fiber annular sample is fixed by adjusting the tightness of the screws, improving practicality. In this embodiment, four through holes 6 are provided along the circumference of each Nol ring cap 4 to improve the stability and strength of the connection.
[0062] In this embodiment, a limiting part 32 is provided at one end of the rotating shaft 3 to restrict the movement of the nore ring cap 4. The edge of the limiting part 32 protrudes from the outer peripheral wall of the rotating shaft 3. The nore ring cap 4 provided at this end is fixedly connected to the limiting part 32, thereby installing each nore ring cap 4 onto the rotating shaft 3. At the same time, the limiting part 32 also serves as a reinforcement. Since the first nore ring cap 4 is fixed, it facilitates the fixing of subsequent nore ring caps 4.
[0063] Taking the installation of a national standard Kornet ring bushing 1 and an American standard Kornet ring bushing 2 on a rotating shaft 3 as an example: The national standard Kornet ring bushing 1 is fitted onto the rotating shaft 3 and slid along the axial direction of the rotating shaft 3 until it abuts against the first Kornet ring cap 4. Then, the second Kornet ring cap 4 is fitted and slid along the axial direction of the rotating shaft 3 until it abuts against the national standard Kornet ring bushing 1. Next, the American standard Kornet ring bushing 2 is fitted and slid along the axial direction of the rotating shaft 3 until it abuts against the second Kornet ring cap 4. Finally, the third Kornet ring cap 4 is fitted and slid along the axial direction of the rotating shaft 3 until it abuts against the American standard Kornet ring bushing 2. The first, second, and third Kornet ring caps 4 are connected together using fasteners 5.
[0064] In this embodiment, a clamping part 31 is provided at the end of the rotating shaft 3 away from the limiting part 32 for connecting to the output shaft of the machine tool. In use, the clamping part 31 is inserted into the clamping parts of the machine, the machine is started, and carbon fiber winding can be performed.
[0065] In this embodiment, the specific testing process is as follows: First, prepare 100.0g of epoxy resin solution and 92.0g of curing agent, stir for 3.0min until homogeneous, and set aside. Second, assemble the national standard Noir ring liner 1, the American standard Noir ring liner 2, and each Noir ring cap 4, and fix the resin-impregnated carbon fiber multifilaments onto the national standard Noir ring liner 1 and the American standard Noir ring liner 2 respectively. Driven by the rotating shaft 3, the carbon fiber multifilaments are wound onto the national standard Noir ring liner 1 and the American standard Noir ring liner 2. Third, place the device in an oven for curing. Fourth, take out the samples wound on the national standard Noir ring liner 1 and the American standard Noir ring liner 2 respectively, cut the samples according to the standard, and conduct a shear strength test on the cut blocks. Under the condition of the same interlayer shear strength, not only is the time shorter and the number of disassemblies fewer, but the workload is reduced, the manufacturing cost is reduced, and the equipment failure rate is reduced.
[0066] This device integrates the national standard Norwegian ring bushing and the American standard Norwegian ring bushing onto a single rotating shaft, solving the problem of frequent tooling changes, cumbersome disassembly and installation of carbon fiber, reducing labor intensity, and improving work efficiency.
[0067] This device shortens the overall experimental time, improves experimental efficiency, reduces the workload of disassembling and installing tooling, reduces the instrument failure rate caused by frequent disassembly and installation, and is convenient and quick to operate.
[0068] This invention is applicable to all types of carbon fibers and other types of fibers. It is not only applicable to large-tow carbon fibers, but also to various types of carbon fibers from 1K to 100K. It is also applicable to dry-jet spun carbon fibers, wet-spun carbon fibers, and gel-spun carbon fibers. It is applicable to strength-type and modulus-type carbon fibers, including high-modulus graphite fibers.
