On October 11, at the annual meeting of the US Army Association in Washington, Army Chief of Staff Mark Milley said that over the years, the US military has been stepping up to provide soldiers with lighter, more durable body armor. And helmet.
US defense contractors like Gentex have come to the Technology Expo organized by the US Army Association to showcase their latest developments in soldier security products. Gentex has developed the Army's advanced combat helmet.
However, with the help of university researchers, the US military's own engineers have taken a major step in developing durable materials to protect the safety of American soldiers.
On October 11, the US Army Research Laboratory and the Massachusetts Institute of Technology Soldier Nanotechnology Research Institute announced that polyurethane urea (PUU) polymers have many benefits. This polymer is 15 times stronger than "steel, but it is as soft as a fiber fabric."
Its super strength is impressive, but its softness is the weapon to distinguish it from the general military body armor. The general military body armor has a hard ceramic and metal plate, which makes it very cumbersome. In contrast, a PUU-like fiber network of the chain armor can be deformed in the event of an impact and then restored to its original thickness. For example, it can absorb the impact of a 7.62 mm caliber shot from an AK-47 assault rifle without damage. Alex Hsieh of the Army Research Laboratory said in a statement that the PUU material actually "can be restored to its original state after being impacted."
The unique molecular structure of PUU fiber means that it can become stronger when subjected to high-speed impact. This material can be changed from a rubber-like form to a glass-like form at high speed deformation. In layman's terms, the greater the impact it receives, the stronger it will become. It is similar to the "bulletproof bag" designed by a US Air Force Academy student in May 2017.
Researchers at the US military and the Massachusetts Institute of Technology are also studying the performance and limitations of this new material. Its potential applications include: transparent masks, bulletproof vests, hand and foot armor and anti-explosive combat boots. The application in a combat helmet may be particularly useful because it prevents the impact of the bullet on the helmet from causing blunt force damage to the soldier's head. And this is a problem that even the most robust protective equipment can't avoid.
PUU polymers are still in the testing phase. However, the US military will eventually speed up the distribution of this thing to its soldiers. In a letter dated October 6, Millai declared that the US military is preparing to revolutionize the way it buys, tests and deploys new weapons and equipment.
“We not only need to deploy a new generation of weapons, but we also need to improve body armor, sensors, radios, and exoskeletons that carry heavy loads,†Mille wrote. “In addition, we must improve by training and assessment. Soldiers’ achievements and judgments.â€
Mille said that if PUU research continues to produce such magical results, then this revolutionary body armor may come in handy as soon as possible.
The OEM pressure core with high performance and high stability is used as the signal measuring element. The sensor signal is converted into standard signal output after special signal processing. After long-term aging and stability screening, the product performance is stable and reliable. It is applied to the outdoor site with poor environment. At the same time, it can display the field pressure, and the zero point and full range can be moved.
Jb400 pressure transmitter installation interface form can not only be processed according to the user's requirements, but also provide specifications compatible with other brands of transmitters. This series of products are widely used in industrial process control, petroleum, chemical industry, metallurgy and other industries.
