Question
Here is the question : IN 1965, DUPONT RESEARCHER STEPHANIE KWOLEK INVENTED WHAT STRONG MATERIAL?
Option
Here is the option for the question :
- Graphene
- Carbon steel
- Kevlar
- Artificial diamond
The Answer:
And, the answer for the the question is :
Explanation:
After working with DuPont for a significant amount of time, Stephanie Kwolek was given the responsibility of searching for the next generation of fibers. As a result of her research, she developed a new category of polymer solutions that had the potential to be transformed into so-called “super fibers.” Kevlar was one of the products that emerged from this category. Since its creation, Kevlar has been used for a variety of purposes, including that of providing police and military personnel with body armor.
Stephanie Kwolek was a researcher at DuPont when she made one of the most important discoveries in the history of materials science. In 1965, Kwolek invented a strong and lightweight material that would eventually become known as Kevlar. Kevlar has since become a critical component in a wide range of applications, from body armor to aerospace engineering.
Kevlar is a type of synthetic polymer that belongs to a class of materials known as aramids. Aramids are characterized by their high strength, excellent resistance to heat and chemicals, and low density. Kevlar, in particular, is known for its exceptional strength and stiffness, making it ideal for use in applications where high tensile strength is required.
One of the most well-known uses of Kevlar is in body armor. Kevlar vests are used by police officers, military personnel, and others who need protection from bullets and other projectiles. Kevlar is also used in helmets, gloves, and other protective gear. Its strength and durability have saved countless lives and prevented numerous injuries.
Kevlar is used in a wide range of other applications. It is used in the aerospace industry to create lightweight and strong components for airplanes and spacecraft. It is also used in the automotive industry to create tires, brake pads, and other components that require high strength and durability.
Kevlar has also found its way into the world of sports. It is used in a variety of athletic equipment, such as skis, snowboards, and hockey sticks. Its strength and stiffness make it ideal for use in these applications, where athletes need equipment that can withstand high forces and impacts.
Kevlar also has some limitations. It is not as flexible as other materials, which can limit its use in certain applications. It is also relatively expensive compared to other materials, which can make it cost-prohibitive for some applications.
Stephanie Kwolek’s invention of Kevlar has had a profound impact on the world of materials science. Its exceptional strength and durability have made it a critical component in a wide range of applications, from body armor to aerospace engineering. Kevlar has saved countless lives and prevented numerous injuries, and its use in sports and other industries continues to grow. While Kevlar has some limitations, its many benefits are clear, and it will continue to play a vital role in shaping the future of technology and society.
