本实施例中方舱大板10包括透射层1、反射层2和夹层结构3，透射层1用于提高雷达波的高透过性，减少雷达波的反射。反射层2用于阻止雷达波进入方舱内部，防止雷达波干扰方舱内设备的正常工作。其中夹层结构3位于透射层1和反射层2之间，夹层结构3包括至少一层第一吸波材料层31和至少一层蜂窝层32，第一吸波材料层31和蜂窝层32层叠设置。其中蜂窝层32具有一定机械强度和隔音隔热效果，同时能够对雷达波进行吸收。即通过第一吸波材料层31和蜂窝层32相互配合，不仅能够提高了雷达波的吸波性能，而且能够提高方舱大板10的刚性强度。In this embodiment, the large board 10 of the shelter includes a transmission layer 1 , a reflection layer 2 and a sandwich structure 3 , and the transmission layer 1 is used to improve the high transmittance of radar waves and reduce the reflection of radar waves. The reflective layer 2 is used to prevent radar waves from entering the interior of the shelter and prevent radar waves from interfering with the normal operation of the equipment in the shelter. The sandwich structure 3 is located between the transmission layer 1 and the reflection layer 2, and the sandwich structure 3 includes at least one layer of first wave absorbing material 31 and at least one layer of honeycomb layer 32, and the first wave absorbing material layer 31 and the honeycomb layer 32 are stacked in layers. . The honeycomb layer 32 has certain mechanical strength, sound insulation and heat insulation effect, and can absorb radar waves at the same time. That is, through the cooperation of the first wave absorbing material layer 31 and the honeycomb layer 32 , not only the wave absorbing performance of radar waves can be improved, but also the rigidity of the shelter slab 10 can be improved.
上述透射层1、反射层2和夹层结构3之间通过粘接胶成型或粘性介质压力成型，如可以通过环氧树脂进行粘接压制等。其中，第一吸波材料层31可以为一层、两层或者更多层。蜂窝层32可以为一层、两层或者更多层。其中，第一吸波材料层31和蜂窝层32层叠设置，可以存在以下几种情况：(1)相邻蜂窝层32之间可以层叠有至少两层第一吸波材料层31；(2)相邻第一吸波材料层31之间可以层叠有至少两层蜂窝层32；(3)至少两层蜂窝层32和至少两层第一吸波材料层31依次层叠设置；(4)蜂窝层32和第一吸波材料层31依次顺序层叠设置。The above-mentioned transmission layer 1 , reflective layer 2 and sandwich structure 3 are formed by adhesive glue or viscous medium pressure forming, for example, epoxy resin can be used for bonding and pressing. Wherein, the first wave absorbing material layer 31 may be one layer, two layers or more layers. The honeycomb layer 32 may be one, two or more layers. Wherein, the first wave absorbing material layer 31 and the honeycomb layer 32 are stacked, and the following situations may exist: (1) at least two layers of the first wave absorbing material layer 31 may be stacked between the adjacent honeycomb layers 32; (2) At least two honeycomb layers 32 may be stacked between adjacent first wave absorbing material layers 31; (3) at least two honeycomb layers 32 and at least two first wave absorbing material layers 31 are stacked in sequence; (4) honeycomb layers 32 and the first wave absorbing material layer 31 are stacked in sequence.
具体地，本实施例中夹层结构3沿透射层1向反射层2方向上依次是蜂窝层32和第一吸波材料层31交替层叠设置。通过将蜂窝层32靠近透射层1设置，以使得雷达波更易进入到夹层结构3中，进而实现雷达波的“透、吸、散”的作用，从而达最大限度地衰减了雷达波并且起到了吸收宽带能量的作用。同时，蜂窝层32和第一吸波材料层31交替 层叠设置，以使得夹层结构3能够对雷达波进行多次吸收散热，进一步提高对雷达波的吸波性能。Specifically, in the present embodiment, the interlayer structure 3 is formed by alternately stacking the honeycomb layer 32 and the first wave absorbing material layer 31 in the direction from the transmission layer 1 to the reflection layer 2 . By arranging the honeycomb layer 32 close to the transmission layer 1, the radar wave can more easily enter the sandwich structure 3, so as to realize the functions of "penetration, absorption and dispersion" of the radar wave, thereby attenuating the radar wave to the greatest extent and playing a role in The role of absorbing broadband energy. At the same time, the honeycomb layer 32 and the first wave absorbing material layer 31 are alternately stacked, so that the sandwich structure 3 can absorb and dissipate the radar wave for many times, and further improve the wave absorbing performance of the radar wave.
如图1所示，在沿透射层1向反射层2方向上依次为蜂窝层32、第一吸波材料层31、蜂窝层32、第一吸波材料层31和蜂窝层32。即蜂窝层32形成有三层，在8～12GHz频率范围内，其吸波性能达-15dB，且随着蜂窝层32层数增加时，吸波性能也随之增加。As shown in FIG. 1 , a honeycomb layer 32 , a first wave absorbing material layer 31 , a honeycomb layer 32 , a first wave absorbing material layer 31 and a honeycomb layer 32 are followed in the direction from the transmission layer 1 to the reflection layer 2 . That is, the honeycomb layer 32 is formed with three layers. In the frequency range of 8-12 GHz, its wave-absorbing performance reaches -15dB, and as the number of layers of the honeycomb layer 32 increases, the wave-absorbing performance also increases.
请参阅图2，图2是图1所示的蜂窝层的横向截面图。Please refer to FIG. 2 , which is a transverse cross-sectional view of the honeycomb layer shown in FIG. 1 .
由于现有的方舱大板10主要用于吸收特定频率的雷达波，而无法满足多频段雷达侦探中的隐身功能。因此，本实施例中蜂窝层32内部结构可以改变，以满足多频段雷达波性能要求。Since the existing shelter 10 is mainly used to absorb radar waves of a specific frequency, it cannot meet the stealth function in multi-band radar detection. Therefore, in this embodiment, the internal structure of the honeycomb layer 32 can be changed to meet the performance requirements of multi-band radar waves.
具体地，蜂窝层32内部结构可以包括蜂窝孔321的横截面形状、蜂窝孔321的横截面孔径大小、蜂窝孔321的密度以及蜂窝孔321沿透射层1向反射层2方向的高度。其中蜂窝孔321的横截面形状为蜂窝孔321横截面轮廓形状；蜂窝孔321的横截面孔径大小为蜂窝孔321孔径面积大小。蜂窝孔321的密度为单位面积内，蜂窝孔321数量多少，蜂窝孔321数量越多，其蜂窝孔321的密度越大，否则蜂窝孔321密度越小。其中蜂窝孔321沿透射层1向反射层2方向的高度为竖向延伸长度，即每层蜂窝层32整体竖向延伸长度数值，其数值越大；蜂窝孔321竖向延伸长度越高，否则蜂窝孔321竖向延伸长度越小。Specifically, the internal structure of the honeycomb layer 32 may include the cross-sectional shape of the honeycomb holes 321 , the cross-sectional aperture size of the honeycomb holes 321 , the density of the honeycomb holes 321 , and the height of the honeycomb holes 321 along the transmission layer 1 to the reflection layer 2 . The cross-sectional shape of the honeycomb holes 321 is the outline shape of the cross-section of the honeycomb holes 321 ; The density of the honeycomb holes 321 is the number of the honeycomb holes 321 per unit area. The more the number of honeycomb holes 321 is, the higher the density of the honeycomb holes 321 is; The height of the honeycomb holes 321 in the direction from the transmission layer 1 to the reflection layer 2 is the vertical extension length, that is, the overall vertical extension length of each honeycomb layer 32, the larger the value; the higher the vertical extension length of the honeycomb holes 321, otherwise The vertical extension length of the honeycomb holes 321 is smaller.
通过上述蜂窝层32内部结构中的任意一个或者多个，均可以增加不同频段的吸波性能，增强隐身功能。无论夹层结构3中只有一层蜂窝层32或者多层蜂窝层32均可以增加吸波频段。Any one or more of the above-mentioned internal structures of the honeycomb layer 32 can increase the wave absorbing performance of different frequency bands and enhance the stealth function. No matter there is only one honeycomb layer 32 or multiple honeycomb layers 32 in the sandwich structure 3, the absorbing frequency band can be increased.
举例而言，当夹层结构3中有三层蜂窝层32时，可以只改变三层蜂窝层32中蜂窝孔321的横截面孔径大小；或者同时改变三层蜂窝层32中蜂窝孔321的横截面孔径大小以及蜂窝孔321的密度；或者均同时改变三层蜂窝层32中蜂窝孔321的横截面形状、蜂窝孔321的横截面孔径大小、蜂窝孔321的密度以及蜂窝孔321沿透射层1向反射层2方向的高度等，在此不再赘述。For example, when there are three honeycomb layers 32 in the sandwich structure 3, only the cross-sectional diameter of the honeycomb holes 321 in the three-layer honeycomb layer 32 can be changed; or the cross-sectional diameter of the honeycomb holes 321 in the three-layer honeycomb layer 32 can be changed at the same time. size and the density of the honeycomb holes 321; or simultaneously change the cross-sectional shape of the honeycomb holes 321 in the three-layer honeycomb layer 32, the cross-sectional aperture size of the honeycomb holes 321, the density of the honeycomb holes 321 and the reflection of the honeycomb holes 321 along the transmission layer 1. The height in the direction of layer 2, etc. will not be repeated here.
在一实施例中，蜂窝层32中蜂窝孔321的横截面形状为六边形和/ 或矩形。其中蜂窝孔321横截面形状为六边形时，蜂窝层32强度更好。当然，蜂窝孔321的横截面形状还可以为其他形状，如正方形、铃形、正弦曲线形、菱形、双铃形或管状形等，在此不作限定。其中蜂窝孔321横截面形状可以根据实际应用场景而定。In one embodiment, the cross-sectional shape of the honeycomb holes 321 in the honeycomb layer 32 is hexagonal and/or rectangular. Wherein, when the cross-sectional shape of the honeycomb holes 321 is hexagonal, the strength of the honeycomb layer 32 is better. Certainly, the cross-sectional shape of the honeycomb holes 321 may also be other shapes, such as square, bell-shaped, sinusoidal, rhombus, double-bell or tubular shape, etc., which are not limited herein. The cross-sectional shape of the honeycomb hole 321 may be determined according to the actual application scenario.
在一实施例中，至少两层蜂窝层32中蜂窝孔321内浸渍有导电材料层，使每层蜂窝层32的蜂窝孔321均有导电材料层，进而使蜂窝层32获得导电性以及低电阻，进而增大吸波、反射损耗面积，提高吸波的效果。In one embodiment, the honeycomb holes 321 of at least two honeycomb layers 32 are impregnated with conductive material layers, so that the honeycomb holes 321 of each honeycomb layer 32 have conductive material layers, so that the honeycomb layers 32 can obtain electrical conductivity and low resistance. , thereby increasing the area of absorbing and reflecting loss, and improving the effect of absorbing.
在实际过程中，蜂窝层32在导电材料层中液体进行浸渍，晾干再浸渍，采用多次浸渍的方法制作而成，以保证浸渍层有足够的厚度。In the actual process, the honeycomb layer 32 is impregnated with liquid in the conductive material layer, dried and then impregnated.
具体地，导电材料层的材料与第一吸波材料层31的材料相同，以通过导电材料层进一步提高蜂窝层32对雷达波的吸波性能。Specifically, the material of the conductive material layer is the same as the material of the first wave absorbing material layer 31 , so as to further improve the microwave absorption performance of the honeycomb layer 32 for radar waves through the conductive material layer.
由于现有方舱大板10的厚度较大，使得由方舱大板10形成的方舱整体重量较重，而影响机车承载方舱的机动能力。因此，本实施例中在不改变原有方舱大板10厚度的基础下，夹层结构3中使用蜂窝层32，降低了方舱大板10的重量，使得机车具有更好地机动能力。Due to the large thickness of the existing shelter slab 10, the overall weight of the shelter formed by the shelter slab 10 is relatively heavy, which affects the maneuverability of the locomotive to carry the shelter. Therefore, in this embodiment, without changing the thickness of the original shelter slab 10, the honeycomb layer 32 is used in the sandwich structure 3, which reduces the weight of the shelter slab 10 and enables the locomotive to have better maneuverability.
在实际过程中，蜂窝层32能够降低方舱大板10的重量。然而，为了进一步降低方舱大板10的重量，蜂窝层32可以为芳纶蜂窝层，芳纶蜂窝层的基材密度为24～144kg/m
3。相比于现有的方舱常用PVC板密度500～600kg/m
3，同体积下的芳纶蜂窝层比PVC板重量可以减少70％～90％。因此，芳纶蜂窝层重量轻、具有较高的强度和隔音隔热特征，芳纶蜂窝层既能保持原有方舱大板10的结构强度，还能更好地降低方舱大板10重量，使机车具有更好地机动能力。
In the actual process, the honeycomb layer 32 can reduce the weight of the shelter slab 10 . However, in order to further reduce the weight of the shelter slab 10 , the honeycomb layer 32 can be an aramid honeycomb layer, and the density of the base material of the aramid honeycomb layer is 24-144 kg/m 3 . Compared with the density of 500-600kg/m 3 of PVC board commonly used in existing shelters, the weight of the aramid honeycomb layer under the same volume can be reduced by 70%-90% compared with the PVC board. Therefore, the aramid honeycomb layer is light in weight, has high strength and sound insulation and heat insulation characteristics. The aramid honeycomb layer can not only maintain the structural strength of the original shelter slab 10, but also better reduce the weight of the shelter slab 10. , so that the locomotive has better maneuverability.

The carbon-based wave-absorbing material layer, the iron-based wave-absorbing material layer, and the ceramic wave-absorbing material layer all have good wave-absorbing properties for radar waves. The first wave-absorbing material layer 31 is only a carbon-based wave-absorbing material layer, or only an iron-based wave-absorbing material layer, or both a carbon-based wave-absorbing material layer and an iron-based wave-absorbing material layer, etc., which are not limited here. .
