Absorbing material: "Black Gold" carbon fiber

The origin of carbon fiber can be traced back to 1860, and it was invented and patented by British Sir Joseph Swan in the production of electric lamp filament. It is a kind ofFibrous carbon materialBlack in color and hard in texture, it is a new type of material with higher strength than steel, lower density than aluminum, more corrosion resistance than stainless steel, higher temperature resistance than heat-resistant steel, and can conduct electricity like copper. It has comprehensive excellent electrical, thermal, and mechanical properties. Due to its difficult manufacturing technology and high practical value, it is known as the "black gold" in the industry.

Carbon fiber has the essential characteristics of carbon materials, as well as the softness and processability of textile fibers, making it a new generation of high-performance reinforcing fibers. Carbon fiber, which is several times thinner than a human hair, can be combined with resin, carbon, ceramics, metal and other substrates through special composite molding processes to obtain high-performance carbon fiber composite materials. These materials can be widely used in many fields such as aviation, aerospace, energy, transportation, military equipment, etc. They are important materials for national defense, military industry and civilian production and life. The biggest feature of the current F-22 fighter jet is its excellent stealth performance, which is closely related to its extensive use of carbon fiber composite materials. In addition, F-117A fighter jets, B-2 stealth bombers, and other aircraft have also adopted itCarbon fiber absorbing materialThe hull of the Swedish "Visby" class patrol ships is made of fully composite materials, which gives them advanced combat capabilities such as high stealth, high maneuverability, and long lifespan. The new high-performance carbon fiber composite material has better stability and reliability, and is currently widely used in equipment systems such as hypersonic vehicles, the International Space Station, and advanced satellites. The US Department of Defense emphasized in its report "Materials Research for 21st Century Defense Needs" that "by 2020, only composite materials have the potential to achieve 20-25% performance improvement in equipment.
