Kevlar is the champion of all fibers. It is the ultimate game changer in its flexibility, strength, durability, and protection. This marvelous fiber is highly heat resistant and strong synthetic fiber compared to other traditionally used fibers such as Nomex and Technora. It has comprehensive applications in industries from the manufacturing of body armor to ropes, tires, and cables. Kevlar is stronger than steel, flexible, and lightweight and its versatility knows no bound.
Kevlar is a synthetic polymer made up of the chemical compound poly para phenylene terepthalamide (PPTA). It is made up of long chain repeating units held by strong chemical bonds. It is composed of 85-90% carbon, 10-14% hydrogen, and a small amount of sulfur, oxygen, and nitrogen. It is not only indestructible but is also highly flexible. Its flexibility makes it the best pick for various manufacturing industries.
Why is Kevlar flexible?
The flexibility of kevlar comes from the way it is manufactured. This synthetic fiber is made up of a long chain of repeating units of its specific chemical structure which are held by strong chemical bonds which give them stiffness and flexibility. Many other flexible materials are also put together in small amounts for the manufacturing of Kevlar which increases its flexibility without slaughtering its durability and strength.
Some of the important materials used additionally to increase the flexibility of Kevlar are;
1 # Nylon
Nylon is greatly known for its strength and flexibility. When combined with kevlar it takes the flexibility of Kevlar to the next level.
2 # Carbon fiber
Carbon fiber is exceptionally lightweight and when unites with Kevlar it not only increases the flexibility of Kevlar but also gives strength.
3 # Glass fiber
Glass fiber is made up of very thin fibers of glass that not only gives flexibility to kevlar but also increases its strength.
4 # Spandex
Spandex is a synthetic fiber best known for its elasticity. When combined with Kevlar it shoots up the elasticity and flexibility of Kevlar.
5 # Polyester
The polyester fabric when amalgamating with Kevlar besides flexibility also improves the durability of Kevlar.
Where does the Flexibility of Kevlar be Employed?
Kevlar is extremely adaptable and has extensive applications due to its top-notch features of flexibility, durability, strength, and resistance. But the most important feature that gives it uniqueness and versatility is its flexibility. Its flexibility makes it a superhero in many industries where strength and flexibility both are required.
Here are some most important uses of Kevlar due to its flexibility;
- Body Armor
As body armors require high strength and extreme flexibility so Kevlar goes best for them. The high flexibility of Kevlar increases the ability of body armor to absorb and distribute impact energy. Thus also used for bulletproof vests and knives.
- Sports Equipment
Kevlar is used for the manufacturing of sports equipment like hockey sticks, footballs, and baseball bats because it provides sky-scraping flexibility without sacrificing strength and resilience.
Kevlar is used in the construction of heavy aircraft because it comes up with high protection against impact.
Kevlar is also used in the construction of military equipment, boats, and vehicles to provide additional strength and flexibility.
Kevlar is commonly used in the automotive industry for the production of tires and barking systems and to give more elasticity and flexibility.
- Fire Fighting and Marine
Kevlar is used in the manufacturing of hose lining, boats, and sails to provide accessory flexibility, strength, and heat resistance.
- PPE and the Medical Industry
Personal protective equipment (PPE) such as gloves and helmets and modern medical applications such as artificial ligaments requires high durability and flexibility. So, Kevlar is the best use for their production.
- Glass Industry and Ropes
Kevlar is used in the glass industry for the manufacturing of flexible and strong window laminates and other glass products. It is also used for the production of flexible, stretchable, and sturdy ropes.
- Textile Industry
Kevlar is widely used in the textile industry for the manufacturing of clothes, bags, and shoes to impart longevity, resistance, and flexibility.
- Power Industry
Power cables and other power pieces of equipment require additional flexibility and strength so kevlar is the best choice for their manufacturing.
In conclusion, Kevlar is a highly flexible, strong, and durable synthetic fiber which makes it good to go in various industries from the production of automotive to medical equipment.
- Is Kevlar stronger than steel?
Kevlar is 5 times stronger than steel on an equal weight basis and provides high durability too.
- Does Kevlar dissolve in water?
Kevlar is a hydrophobic material. It does not dissolve in water nor it absorbs water. Additionally, it is also highly heat resistant.
