Description

Technical Field

[0001] This invention relates to the field of experimental technology for physical properties of composite materials, and in particular to an intelligent monitoring and control platform for the preparation of composite materials by thermo-electric coupling. Background Technology

[0002] The physical properties of metal / carbon fiber composites are affected by factors such as pressure, current, and electrode structure. To determine the parameters corresponding to optimal physical properties, it is necessary to simulate the changes in the physical properties of the composites under energized and pressurized conditions using an energized and pressurized experiment.

[0003] Existing technologies typically use bolts to fix composite material test specimens to the experimental apparatus, which limits the selection of composite material test specimens. Composite materials whose thickness and dimensions do not meet the requirements for bolt fixing cannot complete the electrical pressure test. In addition, it is impossible to simulate situations where multiple composite material test specimens are overlapped or spliced.

[0004] The timing of pressurization significantly alters the mechanical properties of CFRTP / metal composites. Taking CFRTP laminates as an example, premature pressurization leads to excessive resin flow, resulting in localized resin depletion in the composite material; conversely, delayed pressurization results in poor resin flowability, rendering the pressurization ineffective. Therefore, further research into the dynamic mechanical properties of laminates necessitates the design of an adjustable pressurization control device.

[0005] Electrodes are typically mounted in experimental setups using a fixed connection. If the electrode structure needs to be changed, the electrode must be disassembled from the setup and the desired electrode structure installed. This process is inconvenient, and the relative position of the electrode to the composite material specimen cannot be changed during the experiment, making it difficult to determine the electrode position corresponding to optimal physical properties.

[0006] Alternating current and intermittent energization can affect the bonding performance of composite laminates, and different laminate materials exhibit significant differences in temperature properties. Compared to samples energized continuously, samples with intermittent energization may experience more severe corrosion over longer periods. This can lead to bonding failure in the composite laminates.

[0007] In view of this, how to provide a technology that can be adapted to various composite material test pieces and realize intelligent monitoring and control of composite laminates under electrothermal-mechanical coupling is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to provide an intelligent detection and control platform for the preparation of composite materials by thermoelectric coupling, so as to solve the problems existing in the prior art.

[0009] To achieve the above objectives, the present invention provides an intelligent detection and control platform for the preparation of composite materials via thermoelectric coupling, comprising:

[0014] An experimental platform is provided, wherein the main ceramic structure mold is mounted on the experimental platform, and the second limiting mold is connected to a pressurizing mechanism, which is used to apply pressure to the composite material experimental piece through the second limiting mold.

[0015] Furthermore, the first limiting mold includes:

[0016] A limiting plate, wherein the limiting part is connected to the side of the limiting plate;

[0017] A clamping plate is integrally connected to the limiting plate. The clamping plate is located on the side of the limiting plate away from the first electrode cavity. The width of the clamping plate is greater than the width of the limiting groove. When the limiting plate is placed in the limiting groove, the clamping plate is clamped on the front or rear edge of the ceramic structure main mold.

[0018] Furthermore, the pressurization mechanism includes:

[0020] Furthermore, the other side of the composite material experimental piece is spaced apart from the inner wall of the limiting groove.

[0021] Furthermore, the experimental platform includes:

[0022] A base, on which multiple right-angle brackets are vertically arranged, the multiple right-angle brackets being used to form an installation cavity;

[0023] A pressure sensor, wherein the base has a mounting groove adapted to the shape of the pressure sensor, and the pressure sensor is mounted on the mounting groove;

[0024] The main ceramic structure mold is disposed in the mounting cavity, and its lower surface is connected to the pressure sensor.

[0025] Furthermore, it also includes:

[0026] An infrared temperature camera is connected to a fixed bracket, which is connected to the right-angle bracket via an auxiliary bracket. The infrared temperature camera corresponds to the composite material experimental piece, and the main ceramic structure mold has a groove corresponding to the infrared temperature camera.

[0027] A thermocouple is disposed on the side of the composite material experimental specimen.

Compared with the prior art, the electrode structure is very easy to disassemble and assemble, and the electrode structure used in the experiment can be flexibly changed. In addition, the insertion depth of the electrode can be flexibly controlled, that is, the relative position of the electrode and the composite material experimental piece can be changed, thereby determining the electrode position corresponding to the best physical properties.
