What Is Aramid Fiber? – PITAKA
What Is Aramid Fiber?

Aramid fiber (aromatic polyamide) is a synthetic fiber known for being a versatile material with an exceptional strength-to-weight ratio. Aramid fibers were originally developed for specialized applications, such as aerospace and military, but they have found their way into consumer products like phone and tablet cases, and much more.

Aramid Fiber Explained in Detail

Definition and Composition of Aramid Fiber

The term “aramid” is a contraction of “aromatic polyamide,” which refers to the kind of polymer that makes up these fibers. Aramid fibers are composed of long chains of synthetic polyamides (aka, polymers), which are made up of repeating units joined together by amide bonds.

These polymers are aromatic, meaning they have benzene rings within their molecular structure. This composition gives aramid fibers unique properties, including high strength, thermal stability, and resistance to chemical attack.

Chemical Structure of Aramid Fiber

Aramid fibers have a distinct chemical structure that adds to their overall performance. Because of the way their molecules are structured, strong hydrogen bonds can form between chains. This gives them a high tensile strength and elasticity. Aramid fibers can be either para-aramid or meta-aramid, depending on the position of the amide linkages on the aromatic rings.

Thermal Properties of Aramid Fiber

Aramid fibers have a very high melting point – typically above 500° C. Moreover, they don't break down easily at high temperatures. This stability ensures that they maintain their properties even in extreme conditions. Consequently, they can be used in flame-resistant clothing, heat shields, and other applications where resistance to heat is important.

Benefits and Characteristics of Aramid Fiber

In addition to its excellent properties, aramid fiber also showcases some remarkable benefits:

Exceptional Strength
Aramid fibers can be five times stronger than steel and two to three times stronger than glass fiber on an equal-weight basis. This exceptional strength-to-weight ratio makes aramid fibers highly effective in ballistic protection gear, such as bulletproof vests and helmets.

The fibers have a high degree of durability. They resist scratches, abrasions, and being exposed to chemicals for a long time without significantly losing their properties. Because they are naturally tough, aramid fibers are often used to reinforce heavily used products like tires and belts.

Aramid fibers do not conduct electricity and do not interfere with electromagnetic signals. This particular property makes them ideal for electronic accessories like mobile phone cases, where manufacturers aim to prevent interference with wireless signals.

Types and Variants of Aramid Fibers

Para-Aramids vs. Meta-Aramids

Aramid fibers have two main categories: para-aramid and meta-aramid. This classification is based on the position of the amide linkages on the aromatic rings, each with its unique properties and applications.


Para-aramid fibers, such as Kevlar, are known for being strong and flexible. Because they are both very strong and very light, they are perfect for applications where strength is critical, such as aerospace components.

Para-aramid fibers are not only heat-resistant, but they are also resistant to organic solvents. This makes them suitable for high-temperature applications and chemical environments.

Due to their high strength-to-weight ratio, para-aramid fibers are also used in protective gloves, tires, and rope.


Meta-aramid fibers, such as Nomex, are known for their heat and flame resistance. They do not melt easily when exposed to high temperatures, so they are ideal for firefighting gear, protective clothing, and industrial applications that require heat resistance.

Meta-aramid fibers resist chemicals and abrasion, which makes them suitable for protective textiles used in harsh environments.

While meta-aramid fibers are not as strong as para-aramid fibers, they offer superior thermal stability and are more resistant to breaking down at high temperatures.

Aramid Fiber vs. Carbon Fiber

Many people may mistake aramid fiber for carbon fiber due to their similar twilled or plain black and gray patterns. But, they are actually two distinct materials with different characteristics. Below are the key differences between them:

Aramid Fiber
Carbon Fiber
· High tensile strength
· Five times stronger than steel on an equal-weight basis

· Less flexible
· Non-conductive
· Signal-friendly
· Minimized electromagnetic interference
· Conductive
· Can interfere with electrical signals
· Typically golden yellow
· Can be dyed
· Naturally black and gray
· Limited color choices

PITAKA's Aramid Fiber Products

PITAKA's tech accessories include phone cases, iPad cases, AirPods cases, and Apple Watch cases, to name a few. We use the finest aramid fiber and the newest technology to produce the cases that our customers love.

PITAKA Aramid Fiber Phone Cases

Crafted from premium aramid fiber, PITAKA's phone cases are engineered to deliver unparalleled protection from daily wear and tear. Aramid fiber's extraordinary chemical resistance ensures that the cases will retain their original color even after being used for a long time.

Is Kevlar the same as aramid fiber?

Kevlar is a brand name of para-aramid fiber developed by Stephanie Kwolek at DuPont in 1965. Like other members of the aramid family, Kevlar is exceptionally strong, heat-, abrasion- and chemical-resistant, and incredibly lightweight. Kevlar has been used to produce bulletproof vests, body armor, aerospace components, and sports equipment.

What are high-performance fibers?
High-performance fibers are man-made and specifically designed to suit their purpose, e.g., strength, resistance to abrasion, tenacity, or flexibility. Aramid fiber, carbon fiber, and Kevlar are all examples of high-performance fibers.
