New Nanofiber Could Be Used to Safeguard Astronauts and Soldiers
June 30, 2020 No Comments Tech Life Tim Thomas

One of the main issues with protective devices, be it for astronauts, firefighters, or soldiers, is that materials strong enough to safeguard against ballistic hazards typically can’t protect against severe temperature levels and vice versa.As an outcome, the majority of today’s protective gear is made of several layers of different products, that makes it extremely heavy– to the point that it severely limits the user’s movement.

In order to tackle this problem, Harvard University scientists, in partnership with the U.S. Army and West Point, have developed a light-weight, multifunctional nanofiber product that can secure wearers from both extreme temperatures and ballistic risks, such as bullets and shrapnel.Kevlar and Twaron Kevlar and Twaron are 2 commercially offered items that are utilized extensively in protective equipment. They can both provide either ballistic or thermal security, depending upon how they are manufactured.Woven Kevlar’s highly lined up crystalline structure, for example, suggests that it is used in protective bulletproof vests.

Porous Kevlaraerogels, meanwhile, have actually been shown to be extremely protective against heat.” Our concept was to use this Kevlar polymer to integrate the woven, bought structure of fibers with the porosity of aerogels to make long, continuous fibers with porous spacing in between,”Gonzalez said in a Harvard news release.” In this system, the long fibers might resist a mechanical effect while the pores would restrict heat diffusion.”

Paulson School of Engineering and Applied Sciences (SEAS) and a lieutenant colonel in the United States Army Reserve, used immersion Rotary Jet-Spinning (iRJS), a method established by Parker’s Illness Biophysics Group, to manufacture their fibers.Pushing the limits”

While there are enhancements that

could be made, we have pressed the boundaries of what’s possible and started moving the field towards this kind of multifunctional product, “stated Gonzalez.The supreme goal was to design a multifunctional material that

would have the ability to safeguard individuals working in extreme environments, such as astronauts or soldiers.” We have actually shown that you can establish highly protective textiles for people that work in damage’s way, “said Parker.” Our challenge now is to develop the scientific advances to ingenious items for my brothers and sisters in arms.”Harvard’s Office of Technology Advancement has submitted a patent application for the technology and has begun looking for commercialization opportunities for the nanofiber. The team’s research is released in the journal Matter.
