Embodiment 1
[0029] Low infrared emissivity layer: take inorganic phosphate binder, add 10% aluminum powder and mix well, prepare low infrared emissivity layer with 2 layers of basalt fiber checkered cloth as reinforcing material; control the low infrared emissivity layer The mass percentage of the reinforcing material is 45%~60%;
[0030] Radar wave-transmitting layer: use epoxy resin as the matrix material and two-layer basalt fiber checkered cloth as the reinforcing material to prepare the radar wave-transmitting layer prepreg; control the mass percentage of the reinforcing material of this layer to 50%~70%;
[0031] Radar absorbing layer: The basalt fiber roving is washed with acetone to remove the sizing agent on the surface, dried and activated by reaction with nitrile-based resin, and then magnetic nano Fe is added 3 O 4 The powder reaction makes the surface of the basalt fiber graft a large amount of absorbing functional materials to obtain a radar absorbing layer; control the mass perce...
Embodiment 2
[0038] Low infrared emissivity layer: take inorganic phosphate binder, add 15% silver powder and mix well, prepare low infrared emissivity layer with 2 layers of S-glass fiber cloth as reinforcing material; control the low infrared emissivity layer The mass percentage of reinforcing material is 45%~60%;
[0039] Radar wave-transmitting layer: take epoxy resin as the matrix material and use 3 layers of S-glass fiber cloth as the reinforcement material to prepare the radar wave-transmitting layer prepreg; control the mass percentage of the reinforcement material of this layer to 50%~70%;
[0040] Radar absorbing layer: the basalt fiber roving is washed with ethanol to remove the sizing agent on the surface, dried and activated by reaction with nitrile-based resin, and then magnetic nano Fe is added 3 O 4 The powder reaction makes the surface of the basalt fiber graft a large amount of absorbing functional materials to obtain a radar absorbing layer; control the mass percentage of the ...
