New Material Could Mean Lightweight Armor, Protective Coatings

Wednesday, July 21st, 2021

RESEARCH TRIANGLE PARK, N.C. — Army-funded research identified a new material that may lead to lightweight armor, protective coatings, blast shields and other impact-resistant structures.

Researchers at the U.S. Army’s Institute for Soldier Nanotechnologies at the Massachusetts Institute of TechnologyCaltech and ETH Zürich found that materials formed from precisely patterned nanoscale trusses are tougher than Kevlar and steel.

In experiments, the ultralight structures, called nanoarchitectured materials, absorbed the impact of microscopic projectiles accelerated to supersonic speeds.

“Increasing protection while simultaneously decreasing the weight that soldiers carry is an overreaching theme in our research,” said Dr. James Burgess, ISN program manager for the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory. “This project is a really good example of such efforts where projectile energy absorption is nanostructured mechanism based.”

The research, published in Nature Materials, found that the material prevented the projectiles from tearing through it.

“The same amount of mass of our material would be much more efficient at stopping a projectile than the same amount of mass of Kevlar,” said Dr. Carlos Portela, assistant professor of mechanical engineering at MIT, the study’s lead author.

The researchers calculate that the new material absorbs impacts more efficiently than steel, Kevlar, aluminum and other impact-resistant materials of comparable weight.

“The knowledge from this work…could provide design principles for ultra-lightweight impact resistant materials [for use in] efficient armor materials, protective coatings, and blast-resistant shields desirable in defense and space applications,” said co-author Dr. Julia R. Greer, a professor of materials science, mechanics, and medical engineering at Caltech, whose lab fabricated the material.

Nanoarchitected materials are known to feature impressive properties like exceptional lightness and resilience; however, until now, the potential for additional applications has largely been untested.

“We only know about its response in a slow-deformation regime, whereas a lot of their practical use is hypothesized to be in real-world applications where nothing deforms slowly,” Portela said.

To help fill this vital knowledge gap, the research team set out to study nanoarchitected materials undergoing fast deformation, such as that caused by high-velocity impacts. At Caltech, researchers first fabricated a repeating pattern known as a tetrakaidecahedron—a lattice configuration composed of microscopic struts—using two-photo lithography, a technique that uses a high-powered laser to solidify microscopic structures in photosensitive resin.

To test the tetrakaidecahedron’s resilience to extreme, rapid deformation, the team performed experiments at MIT using the ISN-developed laser-induced particle impact array. This device aims an ultrafast laser through a glass slide.. As the laser passes through the slide, it generates a plasma, an immediate expansion of gas that launches the particles toward the target.

By adjusting the laser’s power to control the speed of the microparticle projectiles, the researchers tested microparticle velocities within the supersonic range.

“Some experiments achieved twice the speed of sound, easily,” Portela said.

Using a high-speed camera, the researchers captured videos of the microparticles impacting the nanoarchitected material. They had fabricated material of two different densities. A comparison of the two materials’ impact response, found the denser one to be more resilient, and microparticles tended to embed in the material rather than tear through it.

To get a closer look, the researchers carefully sliced through the embedded microparticles and nanarchitectured target. They found that the struts below the embedded particle had crumpled and compacted in response to the impact, but the surrounding struts remained intact.

“We show the material can absorb a lot of energy because of this shock compaction mechanism of struts at the nanoscale, versus something that’s fully dense and monolithic, not nanoarchitected,” Portela said.

Going forward, Portela plans to explore various nanostructured configurations other than carbon, and ways to scale up the production of these nanostructures, all with the goal of designing tougher, lighter materials.

“Nanoarchitected materials truly are promising as impact-mitigating materials,” Portela said. “There’s a lot we don’t know about them yet, and we’re starting this path to answering these questions and opening the door to their widespread applications.”

The U.S. Army established the MIT Institute for Nanotechnologies in 2002 as an interdisciplinary research center to dramatically improve the protection, survivability and mission capabilities of the Soldier and of Soldier-supporting platforms and systems.

In addition to Army funding through the institute, the U.S. Office of Naval Research and the Vannevar Bush Faculty Fellowship supported the research.

Warrior West 21 – Soliyarn Smart Clothing

Wednesday, July 7th, 2021

Every trade show I attend I have a favorite product or company and my pick for Warrior West 21 is Soliyarn.

This Massachusetts-based tech company was founded on research conducted at UMass Amherst. In a nutshell, they take raw goods and using a vapor technology seamlessly coat a durable, thin film on to textiles. So far they’ve developed conductive, waterproof and anti-microbial coatings.

The conductive tech has been used to heat fabric. The technology works. I put a glove on and the back of my hand immediately began to warm up.

Because there are no cables running through the garment, there’s no need to worry about a cable being cut and losing power. Essentially, the fabric serves as a self-healing circuit. As long as there are fibers still connected, there is a degree of power running through the circuit.

They are currently working with Natick on prototypes of a heated HAHO glove. One of the prototypes seen here is from FirstSpear.

They can also treat the material to be water and oil resistant using a PFC free coating. I watched a demonstration of water being poured on this sample of cotton muslin and the water beaded right off. Not only is the fabric going to remain dry, it’s going to retain it’s comfort and air permeability.

I asked a whole lot of questions like whether or not this will also serve as a data bus. Since this technology is so new, they continue to refine what it can and can’t do. This is a story I definitely plan to follow up on.

Soliyarn technologies are available for unit and agency orders from ADS, Inc.

Uniforms with Programmable Fiber Could Transmit Data and More

Tuesday, June 15th, 2021

RESEARCH TRIANGLE PARK, N.C. — Army-funded research has resulted in the development of a programmable fiber that could transmit data from Soldier uniforms.

Researchers at the Army’s Institute for Soldier Nanotechnologies at the Massachusetts Institute of Technology developed the first fiber with digital capabilities. The fiber can sense, store, analyze and infer activity when sewn into a piece of clothing.

“This groundbreaking research, with other research underway at the ISN, could revolutionize Soldier uniforms,” said Dr. James Burgess, ISN program manager for the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory. “We could outfit our Soldiers with uniforms that could generate power, give them vital information about their physiology and environmental exposures, provide their location to their team and alert someone if they incur an injury. All of this could be done with very little increase in weight carried by the Soldier.”

Ultimately uniforms with this technology could power sensors, store and analyze the collected data and transmit data to outside sources.

The research, published in Nature Communications, describes how the team created the new fiber. The team placed hundreds of square silicon microscale digital chips into a preform that created a polymer fiber. By precisely controlling the polymer flow, the researchers created a fiber with continuous electrical connection between the chips over a length of tens of meters.

Until now, electronic fibers have been analog, carrying a continuous electrical signal, rather than digital, where discrete bits of information can be encoded and processed in 0s and 1s.

The fiber itself is thin and flexible and can pass through a needle, be sewn into fabrics, and washed at least 10 times without breaking down.

“When you put the fiber into a shirt, you can’t feel it at all,” said Gabriel Loke, MIT doctoral student. “You wouldn’t know it was there.”

Yoel Fink, professor in the departments of materials science and engineering and electrical engineering and computer science at MIT said that digital fibers expand the possibilities for fabrics to uncover the context of hidden patterns in the human body for physical performance monitoring, medical inference, and early disease detection.

A digital fiber can also store a lot of information in memory. The researchers were able to write, store, and read information on the fiber, including a 767-kilobit full-color short movie file and a 0.48-megabyte music file. The files can be stored for two months without power.

The fiber also takes a few steps forward into artificial intelligence by including, within the fiber memory, a neural network of 1,650 connections. After sewing it around the armpit of a shirt, the researchers used the fiber to collect 270 minutes of surface body temperature data from a person wearing the shirt, and analyzed how these data corresponded to different physical activities. Trained on these data, the fiber was able to determine with 96 percent accuracy the activity in which the person wearing the shirt was participating.

Adding an artificial intelligence component to the fiber further increases its possibilities, the researchers say. Fabrics with digital components can collect a lot of information across the body over time, and these lush data are perfect for machine learning algorithms, Loke said.

With this analytic power, the fibers someday could sense and alert Soldiers in real-time to health changes like a respiratory decline or an irregular heartbeat, or deliver muscle activation or heart rate data during training exercises. It could also provide data on any toxins Soldiers are exposed to, the length of time they are exposed, and monitor any effects those toxins have on their physiology.

The fiber is controlled by a small external device so the next step will be to design a new chip as a microcontroller that can be connected within the fiber itself.

“When we can do that, we can call it a fiber computer,” Loke said.

The U.S. Army established the MIT Institute for Nanotechnologies in 2002 as an interdisciplinary research center to dramatically improve protection, survivability and mission capabilities of the Soldier and of Soldier-supporting platforms and systems.

In addition to the Army, the, National Science Foundation, the MIT Sea Grant and the Defense Threat Reduction Agency supported this research.
