preparation example Construction

[0046] The invention relates to a preparation method of an artificial electromagnetic material. Compared with the existing preparation method, the whole preparation process can be better monitored, so that each parameter in the process can be accurately controlled, so that the artificial electromagnetic material finally prepared The material not only ensures good electromagnetic properties, but also has good mechanical properties.

[0047] Specifically, such as figure 1 Shown, the preparation method of a kind of artificial electromagnetic material of the present invention comprises the steps:

[0048] P1. Prepare one or more layers of composite materials;

[0049] P2. Laying one end of the fiber grating on the outer surface of the one or more layers of composite material, and connecting the other end of the fiber grating to a monitor;

[0050] P3. Laying one or more layers of composite materials on the outer surface of the layer or layers of composite materials with fiber gr...

Embodiment 1

[0062] P1. Select composite material as prepreg, and stack five layers of prepreg.

[0063] The prepreg includes a base layer and a plurality of (usually hundreds or thousands of) fibers attached to the base layer, and these fibers are spread across the base layer parallel to each other. Preferably, the five layers of prepregs are placed along the same direction of fibers, which can keep the prepregs from being weakly cured and bonded due to different stress directions during subsequent heating.

[0064] P2. Set the grating ends of multiple fiber gratings on the outer surface of the uppermost prepreg, and the direction of the fiber grating placed on the prepreg is 0 degrees, that is, parallel to the fiber direction of the prepreg setting, which can reduce the error caused by stress changes.

[0065] Of course, it is also allowed that the optical fiber grating crosses the fiber direction at a small acute angle.

[0066] The other end of the fiber grating is connected to a mon...

Embodiment 2

[0073] This embodiment has the same steps as the first embodiment, and the difference from the first embodiment is that in step P2, the fiber grating is pretreated before the operation of disposing the fiber grating on the surface of the prepreg.

[0074] Preprocessing includes the following two steps:

[0075] S21. Verifying the fiber grating;

[0076] S22. Clean the fiber grating after calibration.

[0077] Wherein, the implementation of step S21 is specifically as follows image 3 As shown, the grating end of the fiber grating 2 is placed in the oil bath heating mechanism 1, and the other end is connected to a monitor, namely a fiber grating demodulator.

[0078] The oil bath heating mechanism 1 heats up the oil at a heating rate of 2 to 3 degrees Celsius per minute, and at the same time turns on the fiber grating demodulator to record in real time the temperature curve fed back by the fiber grating 2 immersed in the oil, and uses computer software to analyze the deviatio...

Abstract

The invention relates to an artificial electromagnetic material, a manufacturing method of the artificial electromagnetic material, an antenna housing and an antenna system. The manufacturing method of the artificial electromagnetic material comprises the following steps that P1, one or more layers of stacked composite materials are prepared; P2, one end of a fiber bragg grating is laid on the outer surfaces of the one or more layers of composite materials, and the other end of the fiber bragg grating is connected with a monitor; P3, one or more layers of composite materials are laid on the outer surfaces of the one or more layers of composite materials with the fiber bragg grating laid; P4, overall heating and curing are carried out on the composite materials with the fiber bragg grating laid in the middle, and the monitor monitors signals fed back by the fiber bragg grating in the heating and curing process. Through the method, real-time monitoring can be achieved through the fiber bragg grating in the composite materials when the composite materials are heated and cured, and therefore adjustment is carried out in time when heating conditions are inappropriate, and it is guaranteed that the final artificial electromagnetic material have the better electrical property and mechanical property.

Description

technical field [0001] The invention relates to the field of electromagnetic materials, in particular to an artificial electromagnetic material, a preparation method thereof, a radome, and an antenna system. Background technique [0002] Artificial electromagnetic materials are materials that can produce special responses to electromagnetic waves, such as total reflection, total transmission, partial frequency band pass or partial frequency band rejection, etc. On the one hand, the way to achieve these functions is to seek materials with relevant properties, and the other is based on metamaterial technology, which is realized by setting conductive geometric structures with special shapes, sizes and arrangements on existing materials. Among them, the conductive geometric structure plays a decisive role in the electromagnetic properties of the material, while the carrier supporting the conductive geometric structure plays a major role in the mechanical properties of the entire...
