Life Vest There has been proven that 2,800 police officials have been saved by Kevlar. During the seventies, police were looking for something to keep their officers more safe. One officer came across this new material made by DuPont called Kevlar. Originally made to replace steel belts in tires, Kevlar is now depended on by many people. Within years the U.S Army was considering the new polymer for use on the frontlines. Once tested by these government officials they found the material was very resistant to ballistics, and much more effective that the protection used at the time. Lester Shublin once believed that the polymer could not be as effective as it was known for, and there had to be something better. Even with a high budget testing to determine a most reliable of material, they found that Kevlar was the best. The army began using Kevlar vests in 1980. This article is legitimate because the information was recent and the facts had been proven. There is no bias to the opinion of the author. The next level Kevlar was somehow implemented in every sport of the Olympics for 2008, except for the pool sports. What started off as a tire material became material that saves the lives on many people, and changes the way we perform our activities. The first global scale production plant was opened in 2007. DuPont has recently formed alliances with metal companies. The outcome of this alliance is to form a Kevlar composite, that take the characteristics from Kevlar but also from other metals. These composites will be better than what they had before. The polymer composites allow designers less limitations and more freedom in design. This is revolutionary because many of these composites are changing our ways of life. The article is legitimate because the article was published in a magazine, also giving it an unbiased opinion.
Saving Lives with Kevlar The article is about the many uses that the 21st century has found with Kevlar. Some of these uses have made big impacts in our lives. I question the legitimacy of the article,
because it is a personal blog, although the content seems to be informative. The author seems to be credible with the subject matter. Although the makers on the material cannot be traced back to this site, many of the ideas used by the people in the article are interesting. The site is not biased, although the scribe gives his personal professional opinion on many of the ideas. The point of the article is to show how useful the material is, and how good things sometimes come out of mistake. Originally when the material was made for tires, the elasticity properties were not right, but the material has done some many things including saves the lives of many people. Kevlar This site states a brief history on the subject matter. The site is based open the science of Kevlar, and how its worlds. It provides a lot of useful information on the subject matter, and shows such things as the molecular composition of Kevlar and what it is made of, how much it would cost, the different types pouf Kevlar etc. The author is creditable, but anonymous, and is a written as a research paper by a student. The article is in no way bias and it presents both sides of the article, including the good thing and the bad things about Kevlar. This site is legitimate because the student probably wrote the paper for a grade, and the content is very informative.
Invented to save gas, Kevlar now saves lives . "It is one of the most significant pieces of military equipment ever invented," says David Nelson, deputy product manager of clothing and equipment for the Army. The Kevlar is used for required for almost all of the troops in the war in Iraq. Although the material is pricey, it has saved countless lives, from police officers to army men. This article is very detailed, and written in a national newspaper, so it must be legitimate. No bias expressed, and the content is very informative.
