The outer skin of the shelter wall panel provided by the utility model is explained and explained in detail below with reference to the attached drawings.
Fig. 1 is a schematic structural view of an outer skin of a shelter wall panel according to an embodiment of the present invention. As shown in fig. 1, the outer skin of the shelter wall plate provided by the embodiment is in a multi-layer structure form and comprises a composite material layer 1 and a metal fiber layer 2, wherein the composite material layer 1 is a metal-plated carbon fiber reinforced resin-based prepreg tape; the total number of layers of the outer skin is odd, the composite material layers are arranged on the odd layers of the outer skin, the metal fiber layers are arranged on the even layers of the outer skin, namely the metal fiber layer 2 is arranged between every two composite material layers 1.
For example, the total number of layers of the outer skin may be 11, and the composite material layers are arranged on the odd layers of the outer skin, i.e. the 1 st, 3 rd, 5 th, 7 th, 9 th and 11 th layers are the composite material layers. The metal fiber layers are arranged on even layers of the outer skin, namely the 2 nd, 4 th, 6 th, 8 th and 10 th metal fiber layers. The total number of the outer skin layers can also be 15, and the composite material layers are arranged on the odd number layers of the outer skin, namely the 1 st, 3 rd, 5 th, 7 th, 9 th, 11 th, 13 th and 15 th layers are the composite material layers. The metal fiber layers are arranged on even layers of the outer skin, namely the 2 nd, 4 th, 6 th, 8 th, 10 th, 12 th and 14 th metal fiber layers.
In this embodiment, since the metallized carbon fiber reinforced resin matrix has low density and high specific strength, the composite material layer 1 made of the metallized carbon fiber reinforced resin matrix prepreg tape has high strength and corrosion resistance, and can effectively reduce the weight of the cabin body and realize the light weight of the cabin. The metal fiber layer 2 has good conductivity and durability, and realizes the electromagnetic shielding function of the cabin body. After the composite material layers 1 are compounded in multiple layers, the strength of the outer skin can be enhanced, and after the metal fiber layers 2 are compounded in multiple layers, the conductivity of the outer skin can be greatly improved, so that the electromagnetic shielding effect of the outer skin is enhanced. The composite material layers 1 and the metal fiber layers 2 are alternately bonded, so that the strength performance and the electromagnetic shielding performance of the outer skin can be strengthened layer by layer, and the performance of the outer skin is more stable. Therefore, the outer skin of the shelter wall plate provided by the embodiment can solve the contradiction between the light weight of the shelter and the electromagnetic shielding of the shelter in the prior art.
In a possible implementation mode, the metal-plated carbon fiber reinforced resin-based prepreg tape adopted by the composite material layer 1 can be an ultrathin metal-plated carbon fiber reinforced resin-based prepreg tape, the ultrathin prepreg tape refers to a prepreg tape with a single-layer thickness of about 0.08mm, and the structure of the composite material can be optimized by adopting the ultrathin prepreg tape, so that the use efficiency of the composite material is improved.
Alternatively, the resin matrix of the composite material layer 1 may include an epoxy resin, a polyimide resin, or a phenol resin. The material compounded by the resin matrix provided by the optional embodiment can absorb shock and resist radiation, and has good strength at high temperature and stable high-temperature form.
Alternatively, the metallized carbon fiber reinforced resin based prepreg tape may be a nickel plated carbon fiber reinforced resin based prepreg tape.
Alternatively, the metal fiber layer may comprise copper fibers or aluminum fibers.
Alternatively, the monolayer thickness of the composite layer 1 may be 0.05mm to 0.1 mm. Because the composite material layer 1 is a metal-plated carbon fiber reinforced resin-based prepreg tape, the thicker the composite material layer is, the more the required carbon fiber reinforced resin-based prepreg is, the higher the corresponding cost is, the longer the manufacturing period is, and if the thickness of the composite material layer is reduced, the requirement on the strength of the outer skin cannot be met. Therefore, the composite material layer with the thickness of 0.05mm-0.1mm provided by the optional embodiment can meet the strength requirement of the outer skin, the use of raw materials is reduced, and the cost is reduced.
Alternatively, the individual layer thickness of the metal fiber layer 2 may be 0.06mm to 0.15 mm. Because the metal fiber layer 2 is a double-sided conductive copper fiber or aluminum fiber, the thicker the metal fiber layer is, the more the double-sided conductive copper fiber or aluminum fiber is required, the corresponding cost will be increased, and if the thickness of the metal fiber layer is reduced, the requirement of the electromagnetic shielding of the outer skin cannot be met. Therefore, the metal fiber layer with the thickness of 0.06mm-0.15mm provided by the optional embodiment can meet the requirement of electromagnetic shielding of the outer skin, the use of raw materials is reduced, and the cost is reduced.
For example, the composite layer may have a single thickness of 0.05mm, the metal fiber layer may be a double-sided conductive copper fiber, and the single thickness may be 0.15 mm. The single-layer thickness of the composite material layer can also be 0.1mm, the metal fiber layer can also be double-sided conductive aluminum fiber, and the single-layer thickness can also be 0.14 mm.
Optionally, the coverage areas of the composite material layer 1 and the metal fiber layer 2 are the same, so that the outer skin has uniform strength, corrosion resistance and electromagnetic shielding property.
Optionally, the carbon fibers in the carbon fiber reinforced resin matrix prepreg tape are subjected to nickel plating treatment, so that the bonding strength between the carbon fibers in the carbon fiber reinforced resin matrix prepreg tape and the resin matrix can be improved.
In order to simplify the process steps, the composite material layer 1 and the metal fiber layer 2 may be connected by adhesion.
Alternatively, the layers can be bonded by using a conductive adhesive, and the conductive adhesive can be a thermal sensitive acrylic adhesive. The conductive adhesive is adopted for bonding, so that an electric path can be formed between the composite material layer 1 and the metal fiber layer 2, and the electromagnetic shielding effect of the outer skin is improved.
Optionally, the shelter wall panel further comprises an inner skin 3, as shown in the schematic view of the shelter wall panel structure of figure 2.
The outer skin may be provided on a first side of the shelter wall panel; the inner skin may be provided on a second side of the shelter wall panel; and the outer skin is bonded with the inner skin.
Wherein the first side may refer to an outer side of the shelter. The second side may be an inner side of the shelter.
In one possible embodiment, the outer skin may be bonded to the inner skin to form a shelter wall panel. The material of the inner skin can be selected according to the needs, for example, in order to meet the requirements of soft packing, the material of the inner skin can be fiber felt.
In the embodiment, the outer skin provided by the utility model has high bearing capacity and strong electromagnetic shielding capacity, and can meet the requirements of high bearing capacity, low density and high electromagnetic shielding of the shelter without arranging any sandwich layer between the outer skin and the inner skin.
