[0045] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0046] To better understand the technical solutions of the present application, the following will be described in detail in combination with the drawings in the specification and specific embodiments.

[0047] The main solution of the embodiments of the present application is: obtaining the material dielectric constant of the composite material and the temperature data during the curing process; determining the regional curing degree of the composite material based on the material dielectric constant and the temperature data; and controlling the traction speed of the curing process of the composite material according to the regional curing degree.

[0048] Currently, the existing solutions mainly use a variety of sensors (such as humidity sensors, temperature detectors, viscometers, hardness detectors, etc.) to monitor each link in the pultrusion process of composite materials in real time, and use this data for intelligent control. Since the curing state is judged by the temperature and mechanical properties on the surface of the product, the monitoring is not accurate enough. If the internal curing is not sufficient while the surface temperature has reached the standard, it may lead to a decline in product quality.

[0049] The present application provides a solution. During the curing process of the composite material, a dielectric sensor is used to directly detect the degree of cure inside the material, and the curing process is reflected in real time based on the changes in the dielectric constant of the material and the infrared thermal imaging data. The traction speed is dynamically adjusted in combination with the external thermal imaging temperature value to ensure that the traction speed is synchronized with the curing reaction, thereby improving the product yield.

[0050] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as an industrial computer, a processing control device, etc., or an electronic device, a virtual device, etc. that can implement the above functions. Hereinafter, taking the intelligent control device for composite material curing (abbreviated as the control device) as an example, this embodiment and the following embodiments will be described.

[0051] Based on this, the embodiment of the present application provides an intelligent control method for composite material curing, referring to Figure 1 , Figure 1 which is a schematic flowchart provided for Embodiment 1 of the intelligent control method for composite material curing of the present application.

[0052] In this embodiment, the intelligent control method for composite material curing includes steps S10 to S30:

[0053] Step S10, obtaining the dielectric constant of the composite material and the temperature data during the curing process.

[0054] It can be understood that a composite material can be a material composed of two or more different materials with different properties, which is macroscopically composed of new properties through physical or chemical methods. Generally speaking, the above-mentioned constituent materials can be divided into reinforcing materials and matrix materials.

[0055] Exemplarily, the reinforcing materials can include fibers (such as glass fibers, carbon fibers, aramid fibers, etc.), particles (such as ceramic particles, metal particles, etc.), etc. The reinforcing materials can be used to increase the rigidity and strength of the composite material.

[0056] Exemplarily, the matrix materials can include polymers (such as epoxy resins, polyesters, etc.), metals (such as aluminum, magnesium, etc.), ceramics, etc. The matrix material is the main part of the composite material and plays a role in supporting and transmitting loads.

[0057] It should be noted that curing refers to the process in which the matrix material (such as resin) undergoes a chemical reaction and changes from a liquid or semi-solid state to a solid state. In the manufacturing process of composite materials, curing is a key link that determines the final performance of the composite material. Therefore, parameters such as curing temperature, pressure, pulling speed, and time need to be strictly controlled during the curing process to ensure the quality of the composite material.

[0058] In some embodiments of the embodiments of the present application, the above-mentioned composite material of the present application may be self-adaptive polyurethane, epoxy resin, etc. In the embodiments of the present application and the following embodiments, taking self-adaptive polyurethane as an example, the intelligent control method for curing the composite material of the present application will be described in detail.

[0059] In the implementation manner of the embodiments of the present application, a sensing device for obtaining the dielectric constant and temperature data may be installed in the self-adaptive polyurethane pultrusion die, such as a dielectric sensor and a thermal imaging camera, etc. The dielectric sensor data and thermal imaging camera data obtained by the dielectric sensor and the thermal imaging camera are transmitted to the control device through the data acquisition system.

[0060] It can be understood that based on the dielectric sensor data and the thermal imaging camera data, the control device can obtain the material dielectric constant, dielectric loss factor of the composite material, and temperature data during the curing process.

[0061] In some embodiments of the embodiments of the present application, in order to improve the monitoring and control accuracy, the collected data may be filtered to reduce noise interference. The filtering methods that can be used may be Kalman filtering, median filtering, etc., and the embodiments of the present application do not limit this.

[0062] In specific implementation, the control device of the embodiments of the present application can obtain the dielectric constant and temperature data during the curing process of the composite material. Through the combination of the dielectric sensor and thermal imaging technology, it can monitor the curing degree of the composite material in real time and accurately, avoiding the defect of inaccurate monitoring of the curing state in the traditional technology.

[0063] Step S20, determining the regional curing degree of the composite material based on the material dielectric constant and the temperature data.

[0064] It should be noted that the dielectric constant can be a physical quantity that can describe the ability of the composite material to store electrical energy in an electric field. The dielectric constant can reflect the change in the resin molecular structure of the load material during the curing process and is related to the resin curing reaction. The above-mentioned dielectric loss factor can measure the polarization ability of resin molecules. During the curing process, the dielectric loss factor will gradually decrease. The above-mentioned material dielectric constant may include the dielectric constants of the composite material in different curing states, such as the initial dielectric constant before the start of curing, the current dielectric constant that changes during the curing process, and the target dielectric constant after complete curing.

[0065] It should be understood that the above-mentioned temperature data may be the temperature distribution data at different spatial positions during the curing process of the composite material. During the curing process of the composite material, temperature is an important factor affecting the curing rate and curing degree. By monitoring the dielectric constant and temperature data, more accurate curing can be achieved.

[0066] It can be understood that due to different application parts or process requirements, the degree of cure required for different positions of the composite material may be different. At the same time, due to possible uneven temperature distribution or uneven curing agent diffusion during the curing process, in the embodiments of the present application, the composite material can be divided into several regions, and the degree of cure of different regions of the composite material can be calculated separately to obtain the regional degree of cure of each region.

[0067] It should be understood that by monitoring the degree of cure of different regions, the curing conditions of each region can be understood in real time, and the process parameters can be adjusted according to the monitoring results to achieve the desired curing effect, improving the product quality and production efficiency of the composite material.

[0068] It can be understood that the degree of cure can be the proportion converted into a solid state during the curing process of the composite material. In the embodiments of the present application, the degree of cure can be calculated based on the dielectric constant, or based on temperature data, or can be calculated by combining the dielectric constant and temperature data. The value range of the degree of cure can be 0-1. Among them, when the degree of cure is 0, it means uncured, and when the degree of cure is 1, it means completely cured.

[0069] In a specific implementation, the control device of the present application can determine the regional degree of cure of different regions during the curing process of the composite material based on the material dielectric constant and temperature data, which can reflect the curing process in real time, and then realize the dynamic adjustment of the traction speed.

[0070] Step S30, control the traction speed of the curing process of the composite material according to the regional degree of cure.

[0071] It should be noted that when determining the regional degree of cure of each region, it can be evaluated based on the regional degree of cure and the PID algorithm can be used to adjust the traction speed during the curing process according to the evaluation result.

[0072] It can be understood that during the pultrusion process of the composite material, the control device can control the traction speed of the composite material. If the traction speed is too fast, the residence time of the composite material in the mold will be too short, which may lead to incomplete curing, problems such as internal stress, bubbles or insufficient strength; if the traction speed is too slow, although complete curing can be ensured, the production efficiency will be reduced and the production cost will be increased.

[0073] It should be understood that the PID algorithm is an algorithm for closed-loop control based on proportion, integral and differential. By calculating the deviation between the target value and the actual value, and adjusting the control quantity according to this deviation.

[0074] In some embodiments of the present application, the target temperature and target dielectric constant at each stage during the curing process can be set according to the curing process curve of the composite material. Based on the deviation between the current temperature monitored by the temperature sensor and the target temperature, and the deviation between the target dielectric constant and the current dielectric constant, the dynamic adjustment of the traction speed can be achieved.

[0075] It can be understood that the above-mentioned curing process curve can be determined according to the heat conduction model or other methods, and the embodiments of the present application do not limit this.

[0076] In the embodiments of the present application, the material dielectric constant of the composite material and the temperature data during the curing process are obtained; the regional curing degree of the composite material is determined based on the material dielectric constant and the temperature data; and the traction speed control of the curing process of the composite material is carried out according to the regional curing degree. Since the curing process is reflected in real time through the changes in the material dielectric constant and the temperature data, and the traction speed is dynamically adjusted in combination with the external thermal imaging temperature value, it is ensured that the traction speed is synchronized with the curing reaction, and the yield of the pultruded product is improved.

[0077] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar content as in the above-mentioned embodiment one can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 2 , Figure 2 which is a schematic flow chart provided for the second embodiment of the intelligent control method for the curing of the composite material of the present application.

[0078] As Figure 2 shown, in the embodiments of the present application, the step of determining the regional curing degree of the composite material based on the material dielectric constant and the temperature data includes:

[0079] Step S21, determining the first regional curing degree of the composite material based on the material dielectric constant;

[0080] Step S22, determining the second regional curing degree of the composite material based on the temperature data.

[0081] It should be noted that in the embodiments of the present application, each region of the composite material may include the first regional curing degree and the second regional curing degree. Among them, the first regional curing degree is the regional curing degree calculated based on the dielectric constant, and the second regional curing degree is the regional curing degree obtained based on the temperature data.

[0082] Specifically, the material dielectric constant in the embodiments of the present application may include: the initial dielectric constant of the composite material when it is not cured, the target dielectric constant after the composite material is completely cured, and the current dielectric constant monitored during the curing process. The step of determining the first regional curing degree of the composite material based on the material dielectric constant includes:

[0083] Determine the current degree of cure of the first region of the composite material based on the initial dielectric constant, the target dielectric constant, and the current dielectric constant.

[0084] In some embodiments of the present application, the dielectric constant of the composite material decreases during the curing reaction (due to crosslinking to form a solid structure). The calculation method can be as follows:

[0085]

[0086] where α ε is the degree of cure of the first region calculated based on the dielectric constant, ε′init is the initial dielectric constant, ε′final is the target dielectric constant, and ε′ is the current dielectric constant.

[0087] In some embodiments of the present application, the step of determining the degree of cure of the second region of the composite material based on the temperature data includes:

[0088] Determine the current temperature of the curing process of the composite material based on the temperature data;

[0089] Determine the current curing rate constant of the composite material according to the current temperature;

[0090] Determine the degree of cure of the second region of the composite material based on the curing rate constant and the occurrence time of the curing process.

[0091] In the embodiments of the present application, the degree of cure of the second region can be calculated based on the Arrhenius equation, and the specific formula can be as follows:

[0092]

[0093] where α T is the degree of cure of the second region calculated based on the temperature data, and k(T) t is the curing rate constant based on the Arrhenius equation.

[0094] Specifically, the formula for the curing rate constant can be as follows:

[0095]

[0096] where A is the pre-exponential factor (i.e., the empirical constant), E a is the activation energy (the unit can be J / mol), T is the current temperature, and t is the occurrence time of the curing process.

[0097] It should be noted that the above pre-exponential factor and the above activation energy can be determined according to different types of composite materials, and the embodiments of the present application do not limit this. The occurrence time of the above curing process can be obtained by recording the curing process, and the embodiments of the present application do not limit this.

[0098] It can be understood that, in order to improve the accuracy, the regional curing degree can be obtained comprehensively based on the first regional curing degree and the second regional curing degree. That is, in step S23, a dielectric constant weighting factor and a temperature weighting factor are obtained; in step S24, a weighted calculation is performed on the first regional curing degree and the second regional curing degree according to the dielectric constant weighting factor and the temperature weighting factor to obtain the regional curing degree of the composite material.

[0099] In some embodiments of the embodiments of the present application, the method for determining the regional curing degree can be obtained by weighting based on the first regional curing degree and the second regional curing degree. Specifically, it can refer to the following formula:

[0100] α = w1α ε + w2α T ;

[0101] where α is the regional curing degree, w1 is the dielectric constant weighting factor corresponding to the first regional curing degree, and w2 is the temperature weighting factor corresponding to the second regional curing degree.

[0102] It can be understood that the values of the above dielectric constant weighting factor and the above temperature weighting factor can be set according to the requirements in actual applications, and the embodiments of the present application do not limit their specific values.

[0103] In some embodiments of the embodiments of the present application, since the dielectric constant can more intuitively reflect the curing state of the composite material, the above dielectric constant weighting factor can be set to be greater than the above temperature weighting factor.

[0104] In the embodiments of the present application, the current first regional curing degree of the composite material is determined based on the initial dielectric constant, the target dielectric constant, and the current dielectric constant; the current temperature of the curing process of the composite material is determined based on the temperature data; the current curing rate constant of the composite material is determined according to the current temperature; the second regional curing degree of the composite material is determined based on the curing rate constant and the occurrence time of the curing process; a weighted calculation is performed on the first regional curing degree and the second regional curing degree according to the dielectric constant weighting factor and the temperature weighting factor to obtain the regional curing degree of the composite material.

[0105] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, the same or similar content as in the above-mentioned first embodiment and / or the second embodiment can be referred to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 ,Figure 3 Schematic flowchart provided for the third embodiment of the intelligent control method for curing the composite material of the present application.

[0106] As Figure 3 shown, in the embodiment of the present application, the step of controlling the traction speed of the curing process of the composite material according to the regional degree of cure includes:

[0107] Step S31, determining the curing evaluation interval where the regional degree of cure is located;

[0108] Step S32, controlling the traction speed of the curing process of the composite material based on the curing evaluation interval.

[0109] In the embodiment of the present application, for the convenience of controlling the traction speed, several curing evaluation intervals can be divided. When the regional degree of cure is in different curing evaluation intervals, different control methods can be used for the traction speed.

[0110] Specifically, the step of controlling the traction speed of the curing process of the composite material based on the curing evaluation interval includes:

[0111] If the curing evaluation interval is the first curing evaluation interval, then control the traction speed in the curing process of the composite material to decrease;

[0112] If the curing evaluation interval is the second curing evaluation interval, then maintain the traction speed;

[0113] If the curing evaluation interval is the third curing evaluation interval, then control the traction speed in the curing process of the composite material to increase.

[0114] In some embodiments of the embodiment of the present application, the above first curing evaluation interval can be α < 0.5. When in this curing evaluation interval, it can be considered that the current composite material is insufficiently cured, and it is necessary to reduce the traction speed and increase the curing time. The above second curing evaluation interval can be 0.5 ≤ α < 0.9. When in this curing evaluation interval, it can be considered that the current composite material is in the process of curing, and the traction speed can be appropriately adjusted (such as appropriately increasing, appropriately decreasing, or maintaining the current traction speed) to maintain stable production. The above third curing evaluation interval can be α ≥ 0.9. When in this curing evaluation interval, it can be considered that the current composite material is basically cured, and at this time, the traction speed can be maintained or appropriately increased to improve production efficiency.

[0115] It should be noted that when adjusting the traction speed, the adjustment amplitude can be set according to the requirements in actual applications, and the embodiment of the present application does not limit this.

[0116] In the embodiment of the present application, a curing evaluation interval where the regional curing degree is located is determined; if the curing evaluation interval is the first curing evaluation interval, the traction speed during the curing process of the composite material is controlled to decrease; if the curing evaluation interval is the second curing evaluation interval, the traction speed is maintained; if the curing evaluation interval is the third curing evaluation interval, the traction speed during the curing process of the composite material is controlled to increase. Since the traction speed is adjusted by setting different curing evaluation intervals, the dynamic adjustment of the traction speed during the curing process is realized, ensuring that the traction speed is synchronized with the curing reaction, adapting to the changes of raw materials and production materials in different batches, and avoiding the phenomena of incomplete curing or over-curing.

[0117] It should be noted that the above examples are only for understanding the present application and do not constitute a limitation on the intelligent control method for composite material curing in the present application. Based on this technical concept, more forms of simple transformation are within the protection scope of the present application.
