What are the applications of carbon fiber composite materials in the military industry?
One of the main application areas of carbon fiber composite materials is the military industry, where it has many irreplaceable roles.
For aircraft, the faster the flight speed, the higher the economic benefits. For example, for every kilogram of weight reduction of a satellite, the launch cost can be saved by tens of thousands of yuan.
Take military aircraft as an example. For aircraft that reach supersonic speed, such as the J-20 and F-35, reducing the weight by 1 kilogram can not only bring economic benefits of thousands of yuan, but also improve the maneuverability of the aircraft by reducing the weight of the aircraft itself, so that the aircraft can gain a more obvious advantage on the battlefield, which is much more cost-effective than ordinary economic benefits. You know, the more maneuverable the aircraft, the higher the probability of survival on the battlefield, and the less likely it is to be shot down. The economic benefits of saving a supersonic fighter are not just a few thousand yuan.
In addition, the scope of application of carbon fiber composite materials on military missiles is also very wide. The strong and light characteristics of carbon fiber composite materials are also very popular in the missile field. In the early days, it was mainly used in the warhead of missiles and the nozzle of solid engines. While saving weight and cost, it can also increase the strength of the missile body, increase the range of missiles, and improve the accuracy of landing points. The major military powers in the world are making every effort to find ways to apply carbon fiber composite materials to missiles. In addition to warheads and nozzles, rocket shells, rocket launch tubes, etc. have begun to use carbon fiber composite materials.
In addition to land-based missiles, submarine-launched missiles and aircraft-launched missiles are more sensitive to the weight of the missile body, and the proportion of carbon fiber composite materials used is higher. Especially for air-to-air missiles and air-to-ground missiles launched by aircraft, they can increase the aircraft's bomb load and reduce the burden of the aircraft by reducing their own weight, thereby improving the range and strike accuracy of missiles. Therefore, the application of carbon fiber composite materials in airborne missiles is a more necessary choice.
In addition to aircraft and missiles using carbon fiber composite materials, more and more military equipment will use carbon fiber composite materials in the future to give full play to its strong and lightweight characteristics.

Carbon fiber also has a very important application in the military field, that is, the production of special protective clothing. The first is bulletproof vests. Although the current mainstream bulletproof vests are not made of carbon fiber materials, it is not ruled out that bulletproof vests made of carbon fiber materials will be mass-produced in the future. As the production cost of carbon fiber materials continues to decline, its excellent performance advantages are becoming more and more attractive. More and more new bulletproof vests are being developed using special carbon fiber materials. Carbon fiber is used to make the fabric of bulletproof vests. It is light in weight, strong in structure, and has good thermal conductivity. When a bullet hits it, it can not only quickly disperse the force, but also quickly conduct heat to reduce local damage. Of course, carbon fiber can not only be used to make fabrics, but carbon fiber composites can also be used to make the sandwich material of bulletproof vests, that is, protective plates. Since carbon fiber composites can be used to make the skeleton structure on aircraft, it naturally shows that the structural strength of this material is large enough, and it is naturally no problem to use it to make protective plates for bulletproof vests. The key is that the protective plates made of carbon fiber composites are light in weight and strong in structure. While effectively protecting the lives of soldiers, they can minimize the impact on the soldiers' mobility. In addition, carbon fiber composites can also be used to make protective equipment such as bulletproof helmets, and the working principle is similar to that of protective plates.
Carbon fiber can not only be used to make bulletproof vests, but also to make thermal protective clothing and electromagnetic protective clothing. Carbon fiber materials combined with aerogel materials can make very good thermal protective clothing, which can protect soldiers from fighting in high temperature environments and improve the survival ability of soldiers in fires. Carbon fiber itself has good thermal conductivity, which is conducive to dispersing heat and avoiding local overheating, while aerogel can effectively isolate heat. Even if a large external fire is directly sprayed, it will not cause harm to the personnel inside the clothes.
As for electromagnetic protection clothing, it uses the good conductivity of carbon fiber. Carbon fiber itself has good conductivity and can shield electromagnetic waves. In order to enhance the shielding effect, some special ingredients are often added to carbon fiber, which can greatly improve the protection against electromagnetic radiation and avoid electromagnetic radiation from harming the soldiers' bodies.
