Ballistic Protection: New Products and Developments
Ballistic protection: New products and developments In 2017, Teijin Aramid is launching two new ballistic protection products: Endumax Shield XF33, a plate solution for vehicles, vessels and body armor, and Twaron ComForte SB3, a highly flexible solution specifically developed for body armor products. In addition, Teijin Aramid’s Application Competence Center in Wuppertal, Germany, has increased its testing output by 83% over the past year. These developments will allow Teijin Aramid to continue providing a high level of service to its customers, offer a broader product portfolio, and maintain its competitive position in the global ballistic protection market. A unique focus on ballistic protection “For over 30 years, Teijin Aramid has been developing high-performance ballistic protection solutions that have saved countless lives,” says Manon Schuurmans, Business Department Manager Ballistics at Teijin Aramid. “During this time, we’ve built up a complete portfolio of both aramid and UHMW-PE based products and solutions for both personal protection and protective equipment. In addition, our technical team has developed extensive know-how and expertise in several specific ballistic application areas fo body armor, helmets, ground vehicle, vessels and aerospace. Thanks to our experience and state-of-the-art research and development facilities, Teijin Aramid is in a unique position Supported by high levels of technical expertise to address the market needs for ballistic protection.” “We wouldn’t have been able to launch our new products without our high levels of technical knowledge and high- New products: Endumax Shield XF33 and Twaron quality research facilities,” says Manon. “Specifically, our ComForte SB3 Application Competence Center in Wuppertal is “In 2017, we’re launching Endumax Shield XF33 and Twaron instrumental to driving our ballistic protection propositions. -
Contemporary Personal Ballistic Protection (PBP)
Chapter 8 Contemporary Personal Ballistic Protection (PBP) Izabela Luiza Ciesielska-Wróbel Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.69085 Abstract The review concerns existing contemporary protective equipment and their compo- nents serving against ballistic and non-ballistic threats of different sorts. The main focus, however, is on the personal ballistic protection (PBP) based on textile components and their role in the protective elements. Soft ballistic protections are crucial Soft ballistic protections are crucial elements of PBP, forexample in military and law enforcements. Although the subject of PBP was limited in this chapter to soft ballistic protection, other elements, e.g. hard ballistic protection, stab-resistant vests, dual threat, so-called in-con- junction protective elements, modern helmets, were also mentioned in this chapter to demonstrate positioning of the soft ballistic protection and other elements in the global personal protection approach. Apart from it, the chapter contains selected information concerning high-performance polymers and fibres as well as a brief notes about their application in protective panels being basic elements of any protective element. The final remarks concern the most up-to-date approach in relation to ballistic protection, which is immersing high-performance fibres into non-Newtonian liquid substances having the ability of ordering their chemical particles and changing into a high concentration and high segregation lattice under the influence of kinetic energy impact. Keywords: personal ballistic protection, soft body armour, hard body armour, dual threat, stab-resistant vests, bullet-resistant vests, protective panels, high-performance fibres 1. Introduction This chapter provides selected and the most up-to-date information concerning personal ballistic protection (PBP). -

The Evolution of Plate Armor in Medieval Europe and Its Relation to Contemporary Weapons Development
History, Department of History Theses University of Puget Sound Year 2016 Clad In Steel: The Evolution of Plate Armor in Medieval Europe and its Relation to Contemporary Weapons Development Jason Gill [email protected] This paper is posted at Sound Ideas. http://soundideas.pugetsound.edu/history theses/21 Clad in Steel: The Evolution of Plate Armor in Medieval Europe and its Relation to Contemporary Arms Development Jason Gill History 400 Professor Douglas Sackman 1 When thinking of the Middle Ages, one of the first things that comes to mind for many is the image of the knight clad head to toe in a suit of gleaming steel plate. Indeed, the legendary plate armor worn by knights has become largely inseparable from their image and has inspired many tales throughout the centuries. But this armor was not always worn, and in fact for most of the years during which knights were a dominant force on battlefields plate was a rare sight. And no wonder, for the skill and resources which went into producing such magnificent suits of armor are difficult to comprehend. That said, it is only rarely throughout history that soldiers have gone into battle without any sort of armor, for in the chaotic environment of battle such equipment was often all that stood between a soldier and death. Thus, the history of both armor and weapons is essential to a fuller understanding of the history of war. In light of this importance, it is remarkable how little work has been done on charting the history of soldiers’ equipment in the Middle Ages. -
