Hohenstein und DuPont: Innovative Tests für ballistische Schutzwesten

Der Prüf- und Forschungsdienstleister Hohenstein hat in Zusammenarbeit mit DuPont drei innovative und zuverlässige Testmethoden zur Bewertung weicher ballistischer Einlagen entwickelt. Ein hoher Tragekomfort von Schutzwesten, wie z.B. kugelsicheren Westen, und uneingeschränkte Beweglichkeit sind entscheidend für die Leistungsfähigkeit und Ausdauer von Polizei- und Militärangehörigen. Die neuen Methoden beseitigen die Diskrepanz zwischen bestehenden Tests und realen Körperbewegungen und -positionen.

Ein interdisziplinäres Team aus Experten von DuPont und Hohenstein entwickelte die neuen Testmethoden, die eine präzise Bewertung ergonomischer Komforteigenschaften ermöglichen. „Unser Anspruch bei Hohenstein ist es, die realen Bedingungen der Nutzer möglichst genau abzubilden“, erklärt Dr. Jan Beringer, Senior Scientific Expert bei Hohenstein. „Mit gezielten Trageversuchen wurden mögliche Konflikte und Bewegungseinschränkungen ermittelt. Auf der Grundlage jahrzehntelanger Erfahrung wurden dann in enger Zusammenarbeit zwischen DuPont und Hohenstein Tests und dazugehörige Prüfgeräte und Module entwickelt, die das Trageerlebnis simulieren.“

„Um den dringenden Anforderungen von Polizei- und Militärpersonal gerecht zu werden, ist es essenziell, Komfort und Flexibilität in weichballistischen Lösungen zu maximieren. Die Entwicklung von Testmethoden zur Bewertung von Schmerzempfinden und Bewegungseinschränkungen stellt dabei einen wichtigen ersten Schritt dar. Durch die Nutzung der anerkannten Expertise von Hohenstein im Bereich Textilien und Tragekomfort können wir diese Lösungen für die Industrie vorantreiben und den Tragekomfort verbessern, sodass die Einsatzkräfte ihre Aufgaben effizienter erfüllen können“, ergänzte Christophe Djololian von DuPont.

Drei Komfort- und Mobilitätstests

  • Der Lower Costal Bending (LCB)-Test simuliert die Biegebewegung des Oberkörpers. Im Dienst führen solche Bewegungen zu Energieverlusten und schnellerer Erschöpfung des Trägers. Der LCB-Test quantifiziert den Energieverlust aufgrund der Steifigkeit einer ballistischen Schutzweste.
  • Für maximale Mobilität muss sich die ballistische Schutzkleidung optimal an den Körper des Trägers anpassen. Der Double Curvature Compression (DCC)-Test bildet die Form eines gekrümmten Torsos nach und nutzt digitale Bildgebung, um die Anpassungsfähigkeit und Mobilität der Schutzkleidung in den jeweiligen Benutzersituationen zu bewerten.
  • An den Stellen, an denen die Kanten einer ballistischen Weste auf den Körper treffen - am Unterbauch, am Hals oder am Arm - kann der Druck unangenehm sein. Der Edge Pressure (EP)-Test simuliert den Druck der Kanten auf den Körper und misst die dadurch entstehende lokale Druckbelastung.

Die drei Testmethoden zur Bewertung von Komfort und Mobilität von weichballistischen Schutzwesten sind ab sofort bei Hohenstein als Prüfdienstleistung verfügbar. „Je nach Anforderung bieten wir unterschiedliche Lösungen an“, erklärt Dr. Jan Beringer. „Unabhängige, zertifizierte Prüfungen können in den Hohenstein PSA-Laboren mit speziell entwickelten Testgeräten durchgeführt werden. Die drei Testmodule können außerdem käuflich erworben werden, um Herstellern von Schutzwesten die Produktentwicklung sowie die Bewertung der Auswirkungen für die Endanwender zu erleichtern.“

Dyneema® SB301 to Enable Weight Savings of up to 20% in Protective Body Armor Image Avient

Dyneema®: Weight Savings of up to 20% in Protective Body Armor

Dyneema® announced the launch of a next-generation unidirectional (UD) material innovation based on its third-generation fiber at the polymer level: a development poised to enhance the safety and mobility of law enforcement officers and military forces through molecular engineering.

This evolution enables a higher-tenacity fiber – resulting in increased ballistic stopping power when used in the new UD material, Dyneema® SB301, for protective armor applications. The seismic shift in performance enables body armor manufacturers to design soft armor vests 10–20% lighter than previous protective solutions.

Beyond strength, Dyneema® SB301 has the advantage of being made from bio-based Dyneema® fiber, which enables a carbon footprint up to 90% lower than generic high modulus polyethylene (HMPE) fiber.

Now available for use in law enforcement vests for the US market, Dyneema® SB301 material is manufactured in Greenville, North Carolina, in compliance with the Berry Amendment, with additional markets to follow.

“In every situation, weight is now considered to be the top priority after ballistic stopping power,” said Marcelo van de Kamp, global business director for personal protection at Avient. “That’s because survivability is directly tied to weight savings when speed and agility determine outcomes. We’ve long been known as the ‘world’s strongest fiber™,’ but that won’t stop us from finding new opportunities to get stronger. This new product is the latest demonstration of our commitment to both innovation and protection.”

DSM to showcase armor solutions made with Dyneema® at Milipol Paris 2021

DSM, the inventor and manufacturer of Dyneema®, will be exhibiting at one of the leading events for homeland security and safety, Milipol Paris 2021, from October 19-22.

The performance characteristics of Dyneema® make it ideal for a variety of applications, including soft and hard armor ballistics to protect against today’s advanced and emerging threats. In addition, Dyneema® combines next-generation fiber technology and unidirectional engineering to deliver armor solutions with unmatched ballistic stopping power in a lightweight and flexible composite.

By implementing Dyneema®, body armor manufacturers are able to use less material in the development of their ballistic vests, plates and helmets. This leads to weight savings upwards of 30 percent when compared to competitive materials, without impacting ballistic performance. The lightweight construction of armor made with Dyneema® also mitigates injuries associated with the cumulative effects of daily armor use – while improving situational awareness, as well as cognitive and tactical performance.

While decreasing the load on the wearer, Dyneema® is simultaneously able to reduce the impact of material manufacturing on our planet. In line with DSM’s commitment to protect people and the environment they live in, we have developed the first-ever bio-based ultra-high molecular weight polyethylene fiber and unidirectional (UD) material. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE.

DSM/MKU Ltd: High-performance, lightweight ballistic protection in Brazil

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, announced that, together with armor manufacturing partner, MKU Ltd, has provided next generation armor technology with Dyneema® unidirectional (UD) material to support the Sao Paulo police.

The Sao Paulo police, which is comprised of more than 100,000 officers, is the first law enforcement agency in Brazil to initiate a tender for personal protective equipment based on the latest National Institute of Justice (NIJ) .06 standards for body armor, which provide comprehensive and rigorous compliance for the performance and testing of ballistic materials. In addition to NIJ .06 certification, the tender set extremely lightweight requirements for level IIIA soft armor vests.

In addition to NIJ .06 certification, the tender set extremely lightweight requirements for level IIIA soft armor vests.

The hybrid vest solution developed MKU, a global leader in defense and homeland security solutions, for the Sao Paulo police utilizes predominantly Dyneema® UD material to reach new levels of performance and protection while simultaneously enhancing user comfort and mobility. Dyneema®, a strong and light fiber, is the one of leading global brands for ultra-high molecular weight polyethylene (UHMwPE) fiber, UD and fabrics, offering ballistic solutions for personal and vehicle armor that combine maximum strength with minimum weight.

In soft armor applications, Dyneema® offers up to 35 percent weight reduction when compared to competitive materials, while still protecting against both legacy and emerging threats.

In addition to the lightweight armor requirement, the vests were also thoroughly tested to ensure performance with NIJ ballistic reports, NIJ certification and in-house ballistic testing both during the tender process and after the vests were received.

In line with DSM’s commitment to protect people and the environment they live in, one of the world’s first ever bio-based HMPE fibers was introduced in 2020.
