Description

Technical Field

[0001] The present invention relates to the technical field of composite material physical property experiments, and in particular to an intelligent monitoring and control platform for preparing composite materials by thermal and electrical coupling. Background Art

[0002] The physical properties of metal / carbon fiber composites are affected by factors such as pressure, current and electrode structure. In order to confirm the parameters corresponding to the optimal physical properties, it is necessary to use an electric pressurization experiment to simulate the changes in the physical properties of the composites under the electric pressurization state.

[0003] The existing technology generally uses bolts to fix composite test pieces on the experimental device, which limits the selection of composite test pieces. Composite materials whose thickness and size do not meet the bolt fixing requirements cannot complete the power-on pressure test. In addition, it is also impossible to simulate the overlap and splicing of multiple composite test pieces.

[0004] The timing of pressurization has a significant effect on the mechanical properties of CFRTP / metal. Taking CFRTP laminates as an example, pressurization too early will cause excessive resin flow, resulting in poor resin in local areas of the composite material, while pressurization too late will cause poor resin fluidity and lose the meaning of pressurization. Therefore, a more in-depth study of the dynamic mechanical properties of laminates and a controllable pressurization measurement and control device are urgently needed.

[0005] Electrodes are usually installed in experimental devices in a fixed connection. If the electrode structure needs to be changed, the electrode needs to be separated from the experimental device and the required electrode structure needs to be installed. Electrode disassembly and assembly is inconvenient, and the relative position of the electrode and the composite material test piece cannot be changed during the experiment, making it difficult to determine the electrode position corresponding to the best physical properties.

[0006] Alternating current and intermittent power supply will affect the connection performance of the composite board. There is a large difference in the temperature properties of different laminate materials. Compared with the samples with full power supply, the longer the relative time, the more serious the corrosion of the composite laminate samples with intermittent power supply may be. This will cause the connection of the composite laminate to fail.

[0007] In view of this, how to provide a device that can adapt to various composite material test pieces and realize intelligent monitoring and control of composite material laminates under the electrical, thermal and mechanical coupling state is a technical problem that technical personnel in this field urgently need to solve.
