DuPont Announces the Winners of US DuPont Kevlar Innovation Awards

Friday, February 17th, 2012

DuPont Protection Technologies is pleased to announce the winners of the DuPont Kevlar Innovation Awards, which showcase ideas, methods, technologies, applications, products and services using DuPont Kevlar in a new way. This year’s U.S. awards were bestowed in three categories: innovation, protection and collaboration to QinetiQ North America, TYR Tactical and UNEQUAL Technologies, respectively.

They’re excited to announce the winners of these awards that recognize not only incredible ingenuity in uses for DuPont Kevlar, but our partners commitment to industry collaboration to help make the world a better, safer place, said William F. Weber, vice president of DuPont Protection Technologies, North America. DuPont Kevlar is most commonly known for ballistic protection, but its light-weight strength is used for a myriad of other purposes; these award winners showcase some of the best of the wide range of innovative uses of DuPont Kevlar in the industry.

Innovation award criteria focused on the use of DuPont Kevlar with new materials and/or new processing technologies, creativity in the use of DuPont Kevlar in new applications and general uniqueness or impressiveness of the product. The protection award was based on the best demonstration of an innovation that enhances protection of people, processes or the environment using DuPont Kevlar. The collaboration award was given to the entry that best demonstrated ways in which the company worked with DuPont or other organizations to develop a product using Kevlar that provides commercial significance and benefit to others.

QinetiQ North America’s rocket propelled grenade (RPG) protection solution, Q-Net, is the winner in the innovation category. Q-Net provides superior RPG defeat capabilities, is adaptable to a variety of platforms, and is low-cost and ultra-lightweight. QinetiQ worked in conjunction with the Defense Advanced Research Projects Agency (DARPA) and the Office of Naval Research (ONR) to develop the Q-Net system, which is based on nets rather than traditional armor. The system leverages DuPont Kevlar in the netting in combination with metal points at net junctions to create the configuration. DuPont Kevlar was chosen for the netting for its strength, weight and low stretch characteristics. The resulting system offers an innovative solution to vehicle light-weighting and performance challenges, as reducing weight decreases the overall wear and tear of vehicle operating systems and fuel consumption.

TYR Tactical is honored with the protection award for its PV Nylon, a hybrid laminate that is significantly stronger and lighter-weight than standard nylon. TYR Tactical’s PV Nylon demonstrates how scientific innovation can yield incredible hybrid materials that address market challenges. By incorporating DuPont Kevlar to provide increased strength and ballistic resistance at a lighter-weight, TYR Tactical decreased the amount of nylon needed in a protection system, in turn reducing the weight of protection systems overall and increasing the life cycle of each product. This provides the market with a much needed solution for longer-wearing, more resistant and lighter-weight armor.

The collaboration award goes to UNEQUAL Technologies for its EXO pads, which offer body protection to soldiers and athletes. UNEQUAL worked with DuPont to incorporate DuPont Kevlar into its layered pad systems, yielding the first multi-threat, all-fabric solution that reduced fabric thickness, weight and cost. Collaboration with the sports industry allowed UNEQUAL to create padding that protects against blunt force trauma significantly better than traditional foam pads. UNEQUAL relied on Villanova University, Drexel University, Southern Impact Research Center and Safariland/BAE Systems, as well as other industry and academic partners to conduct extensive testing of its EXO Skeleton technology. EXO pads are now used by multiple NFL and NHL teams to help protect players. The different systems are light-weight, thin, and flexible to increase comfort without sacrificing protection on the sports field or battlefield.

The DuPont Kevlar Innovation Awards were judged by a prestigious panel of experts: Professor Philip Brown of Clemson University; Police Commissioner Charles Ramsey; Eric Lin, Ph.D., Chief of the Polymers division at National Institute of Standards and Technology; Adam Rogers, senior editor at Wired; and Doug Muzyka, Chief Science & Technology Officer at DuPont. Each award winner received $10,000 to donate to a charitable organization that benefits education, science, technology and/or government service. QinetiQ donated its award to the Wounded Warrior Project, which provides programs and services to severely injured service members as they recover and transition back to civilian life. TYR Tactical donated its award to Fisher House Foundation, which provides free or low cost lodging to veterans and military families receiving treatment at military medical centers. UNEQUAL donated its award to the National Law Enforcement Museum, which will tell the story of American law enforcement through exhibits, collections, research and education and is expected to open in 2014.

This contest is particularly timely, as DuPont recently opened its new Cooper River plant near Charleston, S.C. the single largest investment in the fiber since its invention. Overall global production capacity for DuPont Kevlar will increase initially by 25 percent and is expected to grow by 40 percent, creating the supply essential to further DuPont Kevlar innovation and new applications by both DuPont and its partners.

Blast From The Past – DuPont Hosts SSD

Wednesday, September 21st, 2011

Since we will soon be talking about FR we thought it would be a great idea to repost last Summer’s visit to Dupont.

DuPont’s Spruance facility in Richmond, Virginia recently hosted SSD for an in depth look at Fire Resistance and Ballistic Protection.

Back in the 60s a new class of fabrics was developed, called Aramids with DuPont at the forefront of their creation. Two fabrics in this class have become the cornerstones of modern Soldier Survivability; Kevlar and Nomex. They provide Ballistic and Fire protection respectively. Kevlar was initially developed by DuPont for tire belts but not put to its current use until the early 70s. Nomex on the other hand was quickly integrated into flying and space suits not long after its creation.

The most compelling portion of the visit was the ThermoMan lab. Composed of 122 sensors, ThermoMan was designed with the assistance of NC State. In addition to the mannequin, there is also a skin burn injury model that takes data collected at the sensors and displays how a thermal threat would equate to an injury to the human body. One interesting aspect of the ThermoMan over other testing methods such as the commonly used vertical flame test is that the ThermoMan tests not only the material’s performance but also the garment’s overall design and construction. This is a critical factor in protecting a wearer from thermal threats. If a flame can get inside a garment then the wearer might as well not be wearing FR at all. Interestingly, the pocket configuration of the issue flight suit is designed to provide additional protection for the wearer by doubling the layers of Nomex in certain key areas. Testing has revealed that most injuries actually occur after the flame threat is removed and the wearer is subjected to residual heat retained by the garment.

We witnessed two burns consisting of a 3 second burn delivering 6 calories. It is intended to replicate a JP4 fire. In the first burn, an issue CWU-27/P US issue flight suit manufactured from Nomex III.

As you can see, minimal damage was sustained by the ThermoMan due to the material and design of the flight suit. it is important to note that while the ThermoMan does a great job predicting injuries, actual injuries may vary due to a wearers body and the fit of the garment. Experience has shown that 1% injury equates to 1 day in the hospital. In this case, the ThermoMan indicated 7% injuries.

In the second, a similar looking flight suit manufactured from 65/35 PolyCotton was subjected to the same threat. PolyCotton, a mixture of 65% Polyester and 35% Cotton is commonly found in Chinese made garments. There IS a place for this fabric, but as you will see in the video, it isn’t in a flame threat environment. Rather, PolyCotton is a cool fabric and very good for use in warm climates. The choice of materials goes back to our recent article concerning knowing your equipment, the threat, and environmental conditions and making an informed choice about which equipment to choose. As you can see the PolyCotton not only caught on fire but it continued to burn even after a direct flame was removed. In this case, the ThermoMan sustained 75% injuries.

During our visit to the ballistics lab we witnessed a demonstration of testing of an armor vest and were introduced to the various apparatus used during testing. Additionally, we were given the opportunity to try out first hand correctional armor which is designed to stop stab and puncture threats. We were amazed at how much differently ballistic and correctional armor reacted to the icepick type of shiv commonly found in correctional facilities. The bottom line is that correctional armor works.

We were fortunate enough to be able to discuss a variety of current Soldier Systems issues with the DuPont team but probably the most important message we got was that DuPont is constantly looking at new ways to use their flagship products. Adaptability is the key as they not work to improve the performance of their materials but also as they seek new ways to use their products as well as combine them with other fibers.

While in years past many vendors would have pushed monolithic solutions to threats, it makes more sense now to develop hybrid solutions that combine multiple fibers into a more robust material. This way, the best characteristics of different materials can be combined into a common solution.

Overall, the meeting was excellent and we left with a greater appreciation of the level of commitment DuPont has to protecting our troops and public safety professionals.
