Of all the tensile fibers in the world none has had a greater impact on the world than Kevlar. It is an almost miracle-like fiber that is responsible for saving countless lives today. However, that is what it appears to have done, at least upon the surface. Kevlar is so much more today than when it was first accidently invented. Imagine a world in which there was no Kevlar, no means to protecting soldiers from bullets, no means to protect those phones teenagers are so crazy about today, or to perhaps to create a glorious display of fire dancing. It would be a dull and boring world without Kevlar in it, a material that few of us know about, yet remains everywhere to be seen just in plain sight.
The question most people have when they hear of Kevlar is usually what is it. Kevlar is light-weight tensile fiber that is incredibly unique due to its chemistry and its properties. Chemically it is a polymer, a polymer is a long chain of molecules all linked together with the same basic unit over and over again, units such as hydrogen and carbon. Two polymers that are very commonplace today are diamonds and graphite, both of which contain many units of carbon, but in different structures with different properties. Kevlar is made up of numerous hydrogen bonds joined together which is why Kevlar is so strong, the hydrogen molecules are always in a constant state of combing with the oxygen molecules. Due to the unique structure, not only is Kevlar strong, but very light, very durable, very resistant to extreme frigid temperatures. Thankfully this innovation when it was first created, happened to be at the hands of the right people at the right time.
In 1964 DuPont wanted or rather need a new product of tire that was light-weight and durable. S...

It is five times stronger, yet the same weight as steel. Kevlar Aramid fiber is an improved material, which is an extremely lightweight, man-made organic fiber. Kevlar fiber has a combination of properties, which have made Kevlar a very useful material. These include, high strength, low weight, high chemical resistance and high cut resistance. This material does not corrode or rust and is also unaffected when placed in or under water.
After graduation, Plank traveled to New York City's garment district to test various materials and eventually designed a material out of spandex and lingerie to be worn under the football pads of athletes. Under Armour's product lines include HeatGear, ColdGear, TurfGear and LooseGear, which can be found in more than 8,000 retail stores and on Under Armour's website. The idea was a major suc...

Tests on Titanic's steel showed that the steel had high sulfur content, which increases the brittleness of steel by disrupting the grain structure [Hill, 1996]. This increase in brittleness contributed to the severity of the hull's
The balloon tires were introduced along with the rail road’s established “piggy-back” service. The first mechanically refrigerated van was introduced. In 1925, there were 500,000 miles of hard surface roads in the U.S. In 1926, a fully loaded 2 ton truck was driven from New York to San Francisco in five days. Theodore Alfred Peterman was the founder of Peterbilt Motors Company in 1937.
This new invention had many better qualities and/or abilities than any other material in use already. Nylons are mostly known for their abilities to be dyed, to be unharmed by many kinds of household cleaning products or greases and oils, its rapid drying time, and above all, its silk-like appearance (The World Book). Nylons¡¯ tensile strength is greater than that of cottons, rayon, silk, and wool (Encarta). They also have characteristics that include elasticity, easy to clean,...
The cylinder phonograph proved to be successful, but the problem with the machine was that the tin foil only allowed a few uses. With the help of another great inventor, new advances could be made to improve this invention. The inventor of the telephone, Alexander Graham Bell, had set up a laboratory for his cousin, Chichester Bell and Charles Tainter. Bell a...
“The first patent for a bent wire paper clip was awarded in the United States to Samuel B. Fay, in 1867. The clip was intended to just attach tickets to fabric, but soon discovered that it can attach papers together.” “The most modern paperclip was invented and patented by William D. Middlebrook in 1899. William didn’t just invent the paperclip, he also invented the machine that makes them.” Mr. Middlebrook’s patent was bought by a manufacturing company,
