EspañolSubmarine noise reduction, missile destroyer noise reduction requirements
The sound-absorbing box composed of foam aluminum sound-absorbing panels and the cavity behind it is installed in the engine room inside the submarine, which can reduce noise by more than 20 decibels, which is conducive to the manufacture of silent submarines. Other ships such as guided missile destroyers also need to use aluminum foam sound-absorbing panels to reduce noise in the engine room and make partition walls.
Crafting Composite Armor Requirements
The new composite armor is composed of ceramic sheets, aluminum foam, and aramid fiberboard. A 20mm thick aluminum foam material is placed in the middle or inner layer. Using the energy-absorbing effect of aluminum foam, the force of the armor-piercing projectile and the armor-piercing projectile is dispersed to prevent it from entering the interior. .
Making vehicle mine-proof bottom plate
The bottom of tanks, armored vehicles, and heavy trucks is V-shaped, with an outer armor plate, a middle layer of foamed aluminum plate, and an inner layer of aramid fiberboard or steel plate, which is mine-proof.
Requirements for military command vehicles and command posts
The aluminum foam material has the function of shielding electromagnetic waves, which can shield more than 90 decibels. It can be used as the lining of military command vehicles and command posts to keep electrical information confidential.
Production anti-riot vehicle requirements
The composite armor of anti-riot vehicles is made of aluminum foam material, and the weight of anti-riot vehicles can be reduced by more than one-third.
Craft a Military Airdrop Crate
At present, my country's military airdrop packaging boxes are made of American Harding technology. The internal energy-absorbing and shock-absorbing material is high-density plastic foam, and foam aluminum is used as the internal energy-absorbing and shock-absorbing material. And the safety of ammunition is increased by more than 10 times.
Make ship explosion-proof deck
The ship deck is made of armor plate, foam aluminum plate and steel plate composite structure, the strength of the deck is increased by more than 2 times, and the anti-blast and ballistic capabilities are increased by more than 2 times.
