Description

Technical Field

[0001] The present invention belongs to the technical field of armored array optical fiber composite reinforcement materials in the direction of measurement technology, and particularly relates to an armored composite optical fiber array material and a processing method thereof. Background Art

[0002] Optical fiber, as a sensing element, performs sensing and measurement based on the principles of optical physics, such as refraction and scattering. Optical fiber must operate under various conditions without breaking or significantly attenuating the light transmission signal. Furthermore, it must maintain stable signal transmission under these conditions. Many researchers, both domestically and internationally, have applied optical fiber sensing technology to monitor stress and strain in steel strands. Existing approaches involve placing single or dual optical fibers within a fiber-reinforced resin (FRP) to create a smart strand, which is then composited with the strand to create a smart strand. This smart strand enables high-precision monitoring of local stress and strain at the measurement points, which is of great significance. However, existing smart strands fail to address issues such as localized damage and signal attenuation caused by stress transfer from the strand to the fiber rods and fibers due to varying locations of the strand, localized stress concentrations, bending, and fatigue fretting corrosion. As the number of coupled fibers increases, simple uniform or centrally stacked fiber configurations become unsuitable. Microstructural analysis and calculations, coupled with the scientific design of multi-layered structures, are essential to fundamentally overcome these detrimental effects.

[0003] With the development of optical fiber technology, the situation where a single optical fiber or two optical fibers are set in the same force reinforcement can no longer meet actual needs. It is necessary to place multiple optical fibers in the same force reinforcement for sensing measurement. The existing technology uses a single optical fiber or a double optical fiber setting method to place multiple optical fibers, but it has caused a variety of technical problems, including but not limited to: slippage between multiple optical fibers under shear force, inconsistent deformation of multiple optical fibers, uneven force in the optical fiber space, uneven deformation of multiple optical fibers, uneven loss of multiple optical fibers, etc.; therefore, simply stacking the number of optical fibers to the center point or simply distributing them evenly by using a single optical fiber or a double optical fiber setting method cannot solve the actual arrangement and construction problems. It is necessary to comprehensively consider factors such as the fiber rod diameter and volume, and develop a scientific optical fiber array structure based on experimental data to ensure that each sub-optical fiber is subjected to uniform force, uniform deformation, uniform loss, and no relative slip.

[0004] Simulation analysis

[0005] Use Rhino to draw the intelligent reinforcement 3D geometric model, such as Figure 19As shown in the figure, the reinforcement pitch is 240mm, the diameter of the central fiber rod is 7.2mm, and six steel wires with a diameter of 4mm are distributed evenly around it. ABAQUS finite element software is used for calculation, and the three-dimensional geometric model is imported into ABAQUS to obtain the calculation model. In the numerical calculation process, the inner ring carbon rod and the outer ring steel wire are regarded as homogeneous solid materials. In addition to the intelligent reinforcement, the fiber rod internal optical fiber and external load model are established in ABAQUS, as shown in the figure. Figure 20 shown.

[0006] In ABAQUS, contact types are mainly divided into two categories: general contact and surface-to-surface contact. General contact is suitable for complex three-dimensional models or scenarios involving multi-body interactions. It supports automatic detection of contact pairs and allows self-contact. Surface-to-surface contact, on the other hand, requires manual definition of master-slave surfaces. Surface-to-surface contact is used for the numerical simulation of displacement between external loads and intelligent reinforcements, with the outer surface of the load as the master surface and the outer surface of the six strands of the intelligent reinforcement as the slave surface. To ensure that the fiber rod is calculated normally under load, the outer surface of the fiber rod is the master surface and the outer surface of the steel wire is the slave surface, and surface-to-surface contact is set.

[0007] During the simulation, a negative gravity load on the Y-axis was applied to the entire model. The smart reinforcement was completely fixed at both ends, and the applied load was applied with a 5mm displacement along the negative Y-axis. By varying the distance between the optical fibers within the fiber rod, the effect of varying spacing on fiber stress under the same external load was studied.

[0008] (1) Small fiber distribution spacing

[0009] Figure 21 The modeled cross-section, stress cloud map, and side-view stress-deformation cloud map of a smart reinforcing fiber rod with small fiber spacing are shown. The three circles marked in the left figure represent three optical fibers arranged in an equilateral triangle, 1 mm from the center point. Simulation calculations show that the stresses at the locations of the three optical fibers are 236 MPa, 300 MPa, and 702 MPa, respectively, and the reinforcing fiber rod is observed to deform at a certain angle. The stress at the location of fiber number 3 is relatively high. If the fiber is subjected to a long-term cyclic stress of 702 MPa, its internal micro-defects, such as surface scratches and coating defects, will accelerate their expansion, eventually leading to brittle fracture. A fiber breakage will directly undermine the integrity of the sensing network, causing distortion or interruption of the strain monitoring signal, seriously affecting the structural health diagnostic function of the smart reinforcing fiber.

[0010] (2) Large optical fiber distribution spacing

[0011] Figure 22This is the modeling cross-section and simulated stress cloud diagram of the intelligent force reinforcement fiber rod with a large optical fiber distribution. The three circles marked in the left figure are three optical fibers, arranged in an equilateral triangle, with a distance of 1.75mm from the center point. After simulation calculation, it can be obtained that the stresses at the positions of the three optical fibers are 300Mpa, 300Mpa, and 702Mpa respectively. It is observed that the force reinforcement carbon fiber lock core shows obvious bending deformation angles. Although the larger optical fiber spacing (1.75mm) reduces stress concentration, it weakens the lateral constraint of the matrix on the optical fiber. During bending deformation, the optical fiber is more likely to displace along the low constraint direction. The symmetry of the equilateral triangle arrangement is destroyed during deformation, which will cause the local load transfer path to shift. The slippage of the optical fiber will change its initial arrangement position, causing the strain monitoring signal to drift or even fail. At the same time, sliding friction will accelerate interface wear and optical fiber breakage.

[0012] Analysis of test data under high stress conditions with small radius bending angle

[0013] Currently, there are only certain studies and experimental data on optical fiber loss under single working conditions of bending angle or micro-stress state in the world:

[0014] Experimental Observation of Critical Bending Radius

[0015] a. Significantly affected bending radius range

[0016] 1. High sensitivity system (spatial resolution ≤ 1m)

[0017] R<10cm: The frequency shift exceeds the system sound (typical noise level 1 to 5 MHz) and can be detected.

[0018] R<5cm: The frequency shift changes significantly (>10MHz) and can be easily misinterpreted as a strain or temperature event.

[0019] 2. Low sensitivity system (spatial resolution > 5m)

[0020] R<3cm: Frequency shift variations may be averaged out but may still be identified as local anomalies.

[0021] Experimental data reference

[0022]

[0023] It has been proven that bending or stress has a great influence on the sensing of optical fiber, but no data literature has been found under complex stress states under bending conditions.

[0024] In this regard, we carried out relevant experimental research and analysis:

[0025] 1. Experimental Research Background: Two spatially symmetrical optical fibers were coupled to a reinforcement structure. Spectra were collected and analyzed at stress stages from 20% / 40% / 60% / 70% of the reinforcement's breaking strength until it broke. The spectral signal data was then processed using an algorithm to identify morphological curves and patterns.

[0026] 2. Set two bending points with angles ranging from 5° to 10°, repeat the above mechanical loading test, and collect data for analysis again.

[0027] Test data such as Figure 23 From the data, we can see that although the optical fiber has stress loss in the straight state, its mechanical linearity and symmetry are very good, which is consistent with the existing calculation models and laws, and is consistent with the laws of international literature.

[0028] from Figure 24 The data shows that the fiber perception is greatly affected by bending and complex stress conditions:

[0029] 1. Under the dual influence of bending and stress, the loss of optical transmission increases exponentially, and the power must be adjusted.

[0030] 2. The optical fibers at different reinforcement positions are affected differently.

[0031] 3. The deformation coordination and synchronization of the optical fiber during bending are affected.

[0032] 4. Spatial positioning is affected by hardware, bending angle and stress.

[0033] Therefore, if multiple optical fibers are required for sensing measurements within the same force bar, the fiber arrangement and construction must be considered. Specifically, sufficient fiber must exist between the sub-fibers to ensure strength, while also ensuring non-slippage and synchronous deformation under shear stress. Simply stacking the fibers at a central point or simply distributing them evenly is insufficient. Considering factors such as the fiber rod diameter and volume, a scientific fiber array construction based on experimental data is required to ensure uniform spatial stress, deformation, loss, and relative slippage across each sub-fiber. Summary of the Invention

[0034] The purpose of the present invention is to provide an armored composite optical fiber array material and a processing method thereof, which overcomes the shortcomings of the existing technology and fills the gap in placing multiple optical fibers in the same force reinforcement for sensing measurement. A multi-fiber array structure based on experimental data science is developed, so that each sub-fiber space is uniformly stressed, deformed, and lost without relative slippage, ensuring the integrity, coordination, sensing accuracy, repeatability and durability of the multi-fiber array under complex force environments. At the same time, the optical fiber array developed in this application can withstand the overall coupling processing technology of the armored outer layer and form a coordinated whole again, becoming a new type of sensing material with multifunctional measurement purposes.

[0035] In order to solve the above problems, the technical solutions adopted by the present invention are as follows:

[0036] An armored composite optical fiber array material includes an optical fiber and a fiber rod composed of carbon fiber, glass fiber, rock fiber, or polymer fiber. The optical fiber is arranged inside the fiber rod to form an independent sub-fiber rod optical fiber. There are multiple sub-fiber rod optical fibers, and the multiple sub-fiber rod optical fibers are 2 or more. The multiple sub-fiber rod optical fibers are woven together to form an optical fiber array bundle.

[0037] Furthermore, the cross-sections of the sub-fiber rod optical fibers are of various shapes, and the sub-fiber rod optical fibers of various shapes are individually woven into a bundle or mixed into a bundle.

[0038] Furthermore, the various shapes include a wavy cross-section, a rectangular cross-section, a hexagonal cross-section, a circular cross-section or a diamond cross-section. The cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a wavy cross-section into a bundle is a wavy optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a rectangular cross-section into a bundle is a square grid optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a hexagonal cross-section into a bundle is a honeycomb optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a circular cross-section into a bundle is a circular grid optical fiber array bundle, and the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a diamond cross-section into a bundle is a diamond grid optical fiber array bundle.

[0039] Furthermore, the outside of the optical fiber array bundle is wrapped and filled with a fiber layer to form a first wrapping layer.

[0040] Furthermore, a second protective cover made of a polymer adhesive is provided outside the first wrapping layer.

[0041] The specific practical application of optical fiber array bundles is mainly used in optical fiber reinforcement. Multiple reinforcements are arranged on the outside of the optical fiber array bundle to couple and process into a whole. The optical fiber array bundle is wrapped in the middle by multiple reinforcements. The multiple reinforcements and the optical fiber array bundle can be filled with or not filled with polymer adhesives for overall processing to weave into multiple optical fiber array reinforcements.

[0042] A method for processing armored composite optical fiber array materials, the specific steps are as follows:

[0043] Step 1: Processing the fiber rod, mixing the adhesive and the fiber and wrapping the mixture around the outside of the optical fiber through a mold, processing the optical fiber into a fiber rod with a wavy cross section, a rectangular cross section, a hexagonal cross section, a circular cross section, or a diamond cross section;

[0044] Step 2: The optical fiber array is braided into a bundle. Two or more sub-fiber rod optical fibers are braided together to form an optical fiber array bundle. The specific cross-sectional form of the sub-fiber rod optical fibers is selected based on the requirements for the overall strength, slippage, loss, and frictional resistance of the optical fiber array. The cross-sectional form of the sub-fiber rod optical fibers within the optical fiber array bundle is a single form or a mixture of sub-fiber rod optical fibers with multiple cross-sectional forms.

[0045] Step 3: Processing the first wrapping layer: wrapping the first wrapping layer on the outside of the optical fiber array bundle through a mold, wherein the first wrapping layer is composed of an adhesive and a fiber mixture;

[0046] Step 4: Processing the second protective cover: Wrapping the second protective cover on the outside of the first wrapping layer through a mold. The second protective cover is made of a polymer adhesive.

[0047] Furthermore, in step 2, when the errors of overall bending strength, relative slip, synchronous deformation, loss, and friction resistance are greater than 30% compared with the fiber rod without optical fiber, a fiber rod with a wavy cross section is used to weave a wavy optical fiber array bundle.

[0048] Furthermore, in step 2, when the error in overall bending strength, relative slip, synchronous deformation, loss, and frictional resistance is greater than 10% to 30% compared to a fiber rod without optical fiber, a fiber rod optical fiber with a rectangular cross-section, a hexagonal cross-section, or a diamond cross-section is used to weave a square grid optical fiber array bundle, a honeycomb optical fiber array bundle, or a diamond grid optical fiber array bundle.

[0049] Furthermore, in step 2, when the errors in overall strength, relative slip, synchronous deformation, loss, and frictional resistance are greater than 1% to 10% compared to the fiber rod without optical fiber, a circular cross-section fiber rod optical fiber is used to weave a circular grid-shaped optical fiber array bundle.

[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] 1. This technology fills the gap of placing multiple optical fibers in the same force reinforcement for sensing measurement, and develops a scientific multi-fiber array structure based on experimental data, so that each sub-fiber is subjected to uniform force, deformation, loss and relative slippage, ensuring the integrity, coordination, sensing accuracy, repeatability and durability of the multi-fiber array in complex force environments.

[0052] 2. By forming a multi-layer armor on the outside of the optical fiber with a fiber rod composed of carbon fiber, glass fiber, geotechnical fiber or polymer fiber, a first wrapping layer, a second protective sleeve, and multiple force bars, the optical fiber can be better protected from bending and complex stress conditions and its adaptability can be improved, thereby increasing its service life.

[0053] 3. The optical fiber array developed in this application can withstand the overall coupling processing technology of the armored outer layer and form a coordinated whole again, becoming a new type of sensing material with multifunctional measurement purposes.

DETAILED DESCRIPTION

[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0078] With the continuous improvement of the demand for fiber optic measurement, it is necessary to realize the sensing and collection of multiple measurement data in the same structure. For example, when the force bar measures strain through the fiber optic, it is necessary to synchronously measure humidity, temperature, vibration, spatial posture, etc. This requires multiple functions and multiple optical fibers to cooperate in real-time perception, and it must also be ensured that the data comparison is meaningful only in the same force unit. Therefore, the multi-fiber armored array technology has been successfully developed and tested under this actual demand. Based on the distributed measurement characteristics of optical fibers, the present invention invents a structure in which multiple optical fibers are placed in the same force bar for sensing measurement, taking into account the arrangement and structural problems of the optical fibers and other technical conditions, namely: there must be enough fibers between the sub-fibers to ensure strength, but they must also meet the requirements of non-slip and synchronous deformation under shear stress. Taking into account factors such as the diameter and volume of the fiber rod, a new optical fiber array is developed based on the scientific array structure of experimental data to ensure that each sub-fiber is uniformly stressed, deformed, lost, and has no relative slip.

[0079] Example 1

[0080] Developed an armored composite optical fiber array material, such as Figures 1 to 18 As shown, it includes an optical fiber 1 and a fiber rod 2 composed of carbon fiber, glass fiber, geotechnical fiber or polymer fiber. The optical fiber 1 is arranged inside the fiber rod 2 to form an independent sub-fiber rod optical fiber 21. There are multiple sub-fiber rod optical fibers 21, and the multiple sub-fiber rod 21 optical fibers are 2 or more. The multiple sub-fiber rod optical fibers 21 are woven together to form a fiber array bundle 3.

[0081] Furthermore, the cross-sections of the sub-fiber rod optical fibers are of various shapes, and the sub-fiber rod optical fibers of various shapes are individually woven into a bundle or mixed into a bundle.

[0082] Furthermore, the various shapes include a wavy cross-section, a rectangular cross-section, a hexagonal cross-section, a circular cross-section or a diamond cross-section. The cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a wavy cross-section into a bundle is a wavy optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a rectangular cross-section into a bundle is a square grid optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a hexagonal cross-section into a bundle is a honeycomb optical fiber array bundle, the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a circular cross-section into a bundle is a circular grid optical fiber array bundle, and the cross-section of the optical fiber array bundle formed by individually braiding sub-fiber rod optical fibers with a diamond cross-section into a bundle is a diamond grid optical fiber array bundle.

[0083] The outside of the optical fiber array bundle is wrapped and filled with a fiber layer to form a first wrapping layer 4.

[0084] A second protective cover 5 made of a polymer adhesive is disposed outside the first wrapping layer.

[0085] Example 2

[0086] The optical fiber array bundle 3 is mainly used on the optical fiber reinforcement. A plurality of reinforcements 6 are arranged outside the optical fiber array bundle and coupled and processed into a whole. The optical fiber array bundle is wrapped in the middle by the plurality of reinforcements. The gaps between the plurality of reinforcements and the optical fiber array bundle can be filled with or not filled with polymer adhesives for overall processing to form a multi-optical fiber array reinforcement.

[0087] Example 3

[0088] The specific processing process of the optical fiber array includes the following steps:

[0089] Step 1: Processing the fiber rod, mixing the adhesive and the fiber and wrapping the mixture around the outside of the optical fiber through a mold, processing the optical fiber into a fiber rod with a wavy cross section, a rectangular cross section, a hexagonal cross section, a circular cross section, or a diamond cross section;

[0090] Step 2: The optical fiber array is braided into a bundle. Two or more sub-fiber rod optical fibers are braided together to form an optical fiber array bundle. The specific cross-sectional form of the sub-fiber rod optical fibers is selected based on the requirements for the overall strength, slippage, loss, and frictional resistance of the optical fiber array. The cross-sectional form of the sub-fiber rod optical fibers within the optical fiber array bundle is a single form or a mixture of sub-fiber rod optical fibers with multiple cross-sectional forms.

[0091] Step 3: Processing the first wrapping layer: wrapping the first wrapping layer on the outside of the optical fiber array bundle through a mold, wherein the first wrapping layer is composed of an adhesive and a fiber mixture;

[0092] Step 4: Processing the second protective cover: Wrapping the second protective cover on the outside of the first wrapping layer through a mold. The second protective cover is made of a polymer adhesive.

[0093] In step 2, when the error in overall bending strength, relative slip, synchronous deformation, loss, and friction resistance is greater than 30% compared to a fiber rod without optical fiber, a fiber rod with a wavy cross section is used to weave a wavy optical fiber array bundle.

[0094] In step 2, when the error in overall bending strength, relative slip, synchronous deformation, loss, and frictional resistance is greater than 10% to 30% compared to a fiber rod without optical fiber, a fiber rod optical fiber with a rectangular cross-section, a hexagonal cross-section, or a diamond cross-section is used to weave a square grid optical fiber array bundle, a honeycomb optical fiber array bundle, or a diamond grid optical fiber array bundle.

[0095] In step 2, when the errors of overall strength, relative slip, synchronous deformation, loss, and frictional resistance are greater than 1% to 10% compared with the fiber rod without optical fiber, a circular cross-section fiber rod optical fiber is used to weave a circular grid-shaped optical fiber array bundle.
