Poly-para-phenylene terephthalamide, or Kevlar, is a polyamide synthesised by reacting two monomers known as 1,4-diamino benzene and benzene-1,4-dicarbonchloride, as illustrated in Figure 2 on Page 2. When such reaction occurs, the two reactants lose a hydrogen atom and a chlorine atom respectively. As a result, Hydrogen Chloride is produced and a covalent bond is formed between Nitrogen and Carbon. With the repetition of this reaction, a chain of these molecules are formed and when multiple chains of kevlar are parallel to one another, the hydrogen atoms of one chain is attracted to the oxygen atoms of another and hydrogen bonding occurs, which is the reason for Kevlar’s stupendous rigidness. This section will specifically analyze the properties…show more content… Simply said, Kevlar is one of the most dynamic materials to have ever been discovered and, as a result, is widely used in a multitude of professions and fields. More specifically, it is most commonly used by the police and military personnels, athletes, and drivers. To begin with, Kevlar is most famously used by military personnels and police officers. Due to its unique chemical properties, Kevlar is extremely light while being extraordinarily tough and rigid. For such reasons, tightly woven Kevlar is the paramount material of almost all commercialized bulletproof vests, providing great mobility and protection against even some of the heaviest firearm and sharpest knives. Outside of battlefields and police stations, Kevlar can also be found in sports venues such as hockey rinks and tennis fields, being used by athletes of all levels. Traditionally, Kevlar is adored as a component of composite hockey sticks, soccer cleats, and tennis strings mainly due to its rigidness and lightness. However, there are also many unconventional applications as well. In recent years, sports brands have used Kevlar in an innovative manner to enhance pre existing designs of common equipment. To illustrate, in recent years, brands such as Bauer and Veba have released hockey socks mainly made of Kevlar that provide the lower leg region unmatched protection against cuts and hits. Moreover, a popular sports brand, Reebok, has even developed a sports bra infused with Kevlar as such allows for exceptional support, protection, and ventilation. Finally, whether it is a Formula-1 driver or a truck driver, almost any jobs concerned with automotive vehicles use Kevlar. Due to its remarkably high tensile strength, Kevlar is an essential continuent in automotive components such as belts, hoses, and clutches. Furthermore, with the advancement of technology, its use in the
