Aramid fiber is also known as aromatic polyamide. They are a type of strong and heat-resistant synthetic fibers. Their molecules have relatively rigid polymer chains and strong hydrogen bonds. These characteristics make aramid fibers capable of effectively transferring mechanical stress.

Some general characteristics that make aramid fiber different from other synthetic fibers include:

• High melting point of more than 500 degrees Celsius

• Good abrasion resistance

• High strength
  ​

Because of these properties, you can use aramid fiber to make armor, protective clothing like bullet proof vests and numerous other applications. In the 1970s, aramid fiber was first used to reinforce vehicle armor. You can also use them in constructing optical fiber cable systems and diaphragms in loudspeakers.
