A Quick Guide to Aramid Fiber, Kevlar and Carbon Fiber Materials

The Science Behind Phone Cases

Smartphones have become a lifeline for many people worldwide. They're not just tools for communication and entertainment; they're extensions of our personalities and daily needs. As technology continues to progress, we're lucky enough to get our hands on the latest devices with sleek designs, powerful processors, and outstanding cameras. However, smartphones aren't indestructible. If you want to improve your device's protection without sacrificing aesthetics, consider arming your phone with high-quality protective case made of Aramid Fiber, Kevlar, and Carbon Fiber. In this blog post, we delve into the key differences between these high-performance materials and why you should invest in these protective accessories for your phone.

Aramid Fiber

Aramid Fiber is a synthetic material that is both lightweight and incredibly strong. It was initially developed in the 1960s and has since been used in a variety of applications, including aerospace, military, and automobile industries. Due to its impressive strength-to-weight ratio, Aramid Fiber has proven itself to be highly effective in protecting sensitive electronic devices, especially smartphones. Military-grade phone cases made from Aramid Fiber are lightweight and slim, providing a comfortable grip while also offering adequate protection from everyday wear and tear. The material is heat-resistant, so your iPhone 14 Pro Max is safe from overheating issues, even under demanding usage scenarios.


Kevlar, a type of Aramid Fiber, was invented by Stephanie Kwolek in 1965 and is primarily known for its use in bulletproof vests. Like Aramid Fiber, Kevlar is immensely strong, lightweight, and heat resistant. It possesses these characteristics due to its unique molecular structure, which consists of long chains of molecules that interlock through hydrogen bonds. This structure allows Kevlar to absorb and disperse energy from impacts effectively. Besides, Kevlar is highly resistant to wear and tear and can maintain its form even when flexed. Smartphone cases that utilize Kevlar as the primary material can provide military-grade protection, ensuring that your device remains safe under most circumstances.

Different Fiber Materials for Phone Case

Carbon Fiber

Carbon Fiber is another advanced material that has gained popularity in recent years for its use in phone cases. It is a composite material made up of carbon atoms that have been bonded together to form microscopic crystals. When woven and combined with a resin, Carbon Fiber is known to have a unique appearance with a checkerboard pattern that is both visually appealing and incredibly strong. The material's tensile strength surpasses that of steel, while its weight remains comparable to plastic. This makes carbon fiber phone cases some of the most lightweight protective case available on the market today. So, if you're looking for an extra layer of protection for your device, a phone case made from carbon fiber may be just what you need.

Which Case Is Right For Me?

When it comes to choosing among Aramid Fiber, Kevlar, and Carbon Fiber cases, it all boils down to personal preference and specific requirements. If you're looking for a slim and stylish option that provides reliable protection without adding bulk, Aramid Fiber cases are the perfect choice. On the other hand, if you need something that offers the ultimate level of protection with bulletproof capabilities, Kevlar cases might be your go-to choice. Lastly, if you want a blend of functionality, strength, and eye-catching aesthetics, Carbon Fiber cases would fit the bill.

While these high-performance materials undoubtedly provide excellent protection for your smartphone, it's essential to remember that no case is 100% infallible. Accidents can happen, and even the most formidable protective cases might not withstand every potential damage scenario. As such, it's crucial to treat your phone with care and invest in additional protective measures like screen protectors and waterproof pouches when necessary. Furthermore, choose a trusted brand like Thinborne when buying cases made from these materials, as poor craftsmanship can negate their effectiveness. 


What is Aramid Fiber Made of?

Aramid fiber is a type of synthetic material composed of polyamide molecules connected by strong covalent bonds. It is often referred to as “para-aramid” because the chemical structure forms para-bonded aromatic rings, giving it its unique properties. Aramid fibers are highly flexible and lightweight yet possess incredible strength, making them ideal for use in a range of applications.

What are The Disadvantages of Aramid?

Aramid fibers are a popular material used in protective phone cases. But they also come with some drawbacks. The most significant disadvantage of aramid is its cost.  It can be more expensive than many other materials.

Another issue associated with aramid is that it's not biodegradable. Thus, it has an impact on the environment when disposed of improperly. Similarly, the production process for aramid fiber does involve some toxic chemicals which have an adverse effect on the environment if mishandled or released into natural ecosystems.

What is Kevlar Made From?

Kevlar is a synthetic fiber that was developed in 1965 by Stephanie Kwolek. It is made of Poly-Paraphenylene Terephthalamide (PPTA). It has an impressive strength to weight ratio which makes it suitable for many products. Kevlar also has excellent thermal stability and chemical resistance, making it very durable over time and capable of withstanding harsh conditions.

Carbon Fiber

Is Carbon Fiber Stronger than Steel?

Yes, Carbon fiber is indeed stronger than steel. Carbon fiber is a composite material made of thousands of fine and intertwined fibers that are incredibly strong and lightweight at the same time. It has become a popular material in the manufacturing industry due to its strength-to-weight ratio. It's five times as strong as steel but weighs only one-fourth as much.

In fact, carbon fiber has such impressive properties that it's even been used to create phone cases! The slim and lightweight characteristics make carbon fiber a fantastic choice for enclosing electronic devices like smartphones. Plus, its incredible durability allows it to withstand everyday scrapes and bumps with ease.


Smartphones are expensive investments, and it's only natural that we want to protect them with the best materials available. By opting for a case made from Aramid Fiber, Kevlar, or Carbon Fiber, you're not only ensuring that your smartphone has enhanced protection but also adding a touch of sophistication and style. These materials offer remarkable strength and durability while maintaining a lightweight and slim profile. They've proven their worth in various sectors, and there's no doubt that they'll serve your smartphone well. Begin your search for the perfect Aramid, Kevlar, or Carbon Fiber phone case today and experience peace of mind knowing that your beloved device is well-armored against life's unexpected challenges.
