Composite metal foam (Cmf) Finally ready for production after many years of intense testing (CMF) is finally ready for production after many years of intense tests.
This material is not like anything created. It is noteworthy that CMF combines the strength of steel with ease of aluminum and is resistant to ballistic shocks, fire and radiation.
Rabbia, Aphseneh, Nonsky University, has been improving CMF for over ten years. Advanced Materials Manufacturing (AMM) has recently announced its readiness for full -scale metal foam production. After testing, CMF technology has proven efficiency in weight loss, carbon size and emissions, as well as in improving the safety and productivity of modern engineering structures.
This durable and lightweight material consists of a network of hollow metal bubbles integrated into a matrix of steel, titanium, aluminum or other alloys. According to Rabia, CMF is the strongest metal foam, although it is not the first of its kind.
In the 2019 study, scientists have found that CMF armor provides equivalent protection against caliber balls .50 (Both bullet and armor) compared to conventional steel armor. The CMF layer absorbed 72-75% of the kinetic energy of ball balls and 68-78% of armor -piercing balls. Particularly important, CMF armor has reached this weight protection, which is less than half the weight. A significant weight loss, which is provided by CMF armor means improving the performance of the car and saving fuel.
Over the past few years, metal foam has been a strict test to evaluate its resistance to ballistic influences, explosions, vibrations, radiation and fire. CMF is also great for thermal insulation. The 2016 study, published in the International Journal of Thermal Sciences, showed that CMF isolates much better than solid metal. Researchers have subjected a solid sheet of stainless steel and a sample CMF exposure to flames with a temperature of 1472 ° F (800 ° C). Steel reached a certain temperature in four minutes, while CMF took twice as much time – eight minutes. Excellent CMF thermal insulation is due to air pockets inside its structure. As the slaves explained, the heat spreads slower than metal. This property makes CMF suitable for the protection of heat -sensitive materials – from dangerous chemicals to spacecraft.
CMF is promising for the construction of spacecraft due to its radiation protection properties. The material proved its effectiveness against x-rays and gamma rays-dangerous radiation widespread in space. It also demonstrates the potential to block neutron radiation, such as that is produced by nuclear reactors and explosions.
“In short, CMF is promising for a variety of use: from the study of space to transportation of nuclear waste, explosives and hazardous materials, military and security applications and even cars, buses and trains,” Rabia said in the previous press release.
AMM has announced the start of receiving orders for the manufacture of individual structures of CMF of different shapes, sizes and materials.
