  • 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).

    ISSN: 2455-2631 © January 2016 IJSDR | Volume 1, Issue 1 Bulletproof Vest and Its Improvement – A Review Naveen Kumar Department of Mechanical Engineering JIET, Jodhpur, India Abstract – The aim of this paper to study bulletproof vest. The material Kevlar, spectra shield, twaron are used in making bulletproof vest. History of armors used in many countries. Making of Kevlar and by using it making of bulletproof vest. Study and classification of bulletproof vests - Type I, Type IIA, Type II, Type IIIA, Type III, Type IV. Quality control and tests for vest like fiber and yarn tensile strength, the tensile strength of the resultant cloth Spectra is also tested for tensile strength by the manufacturer. Bulletproof vests are tested both wet and dry. This is done because the fibers used to make a vest perform differently when wet. Tests for check quality of jacket A. Ballistic testing V50 and V0 B. Military testing: fragment ballistics. We can improve performance by using grapheme. It can absorb more impact of bullet as compare to Kevlar. UHMWPE (Ultra-high-molecular-weight polyethylene).Recently a new fabric developed at the University of California which can make sweat away from our skin. Bullet proof vest must be durable so Cardura can be used .for waterproofing we can use Gore-Tex. Dyneema is a waterproof material if we use we can make light weight bulletproof vest as it doesn’t require waterproofing. Keywords – Kevlar, spectra, twaron, UHMWPE, Dyneema ___________________________________________________________________________________________________________ I. Introduction Bulletproof vest is a vest which can protect wearer’s body from the impact of bullet. This vest can’t bear the total impact of bullet but it can bear most of the impact of bullet.

It had civilized lands of modern nations, rich histories decorated with artists and artisans, religion, politics and rampant urbanization. Ideology and doctrine rose up to conflagrate the age old border disputes and national tensions until full fledged war broke out. Armies marched to the front lines, ponderous mecha belching diesel fumes, and the forces clashing on battlefields of barbed wire, mud, and misery. Until One night, with the shadow of another day’s bloody dawn rising, there came a shuddering rumble and a flash of light. Millions of dancing colors scintillated in the black sky, throwing ghostly shadows dancing, and the earth shook below. The front lines of armies shattered and scattered, the borders redrew in an instant, and the continents themselves buckled and heaved. The great spine of the world snapped under the weight of war and strife. The very Airth died that fateful night. The Cataclysm broke the world open, and scattered the land itself to the heavens.

  • Aspects Regarding the Use of Polyethylene Fibers for Personal Armor
    ASPECTS REGARDING THE USE OF POLYETHYLENE FIBERS FOR PERSONAL ARMOR LUMINIȚA-CRISTINA ALIL1 CRISTIAN BARBU1 SIMONA BADEA2 FLORIN ILIE3 Abstract: The last few decades represented a revolution for the ballistic protection industry, by introducing the aramids, the world-known Kevlar, into the protective structures, especially body armour and lightweight armour. This accomplishment also introduced the opportunity for other polymers to make their way into ballistic protection domain. Nowadays, high-perfomance polyethylene is the real competitor of aramid. This articles offers a global view over the state-of-the-art of the development of this type of polyethylenes in the ballistic protection domain, mentioning some local recent research that has been made on this subject. Keywords: high-performance polyethlylene, ballistic protection, lightweight armour 1. Introduction Ballistic protection is known as a very dynamic field which, from the very battlefield point of view, is constantly competing against the development of ammunition, pyrotechnics and, more recently, improvised explosive devices (IED). Personal armor items are also comercialised as ballistic clothing, therefore we may say that fibers play a very important role in this industry. There are many natural and synthetic fibers which are used for ballistic protection, but only two types of synthetic fibers can be regarded as high-performance – aramid and UHMWPE (Ultra High Molecular Weight Polyethylene) fibers. [1] The modern bulletproof vest using Kevlar fibers emerged in the 1970s and since then, many materials made their way into enhancing the ballistic protection or even replacing standard materials, such as metal and ceramics, resulting in lighter, more comfortable to wear protection equipment, the so called ”lightweight armour”.
