When it comes to body armor, two materials often come up in discussion: Kevlar and aramid. But what exactly are these materials, and how do they differ? At Pivotal Body Armor, we're experts in protective gear and want to help you understand the key distinctions between Kevlar and aramid.
Our soft body armor collection features top-quality Kevlar and aramid options from trusted brands. Let's dive into what makes these materials unique.
What is Kevlar?
Kevlar is a registered trademark of DuPont and a specific brand of aramid fiber. It was first developed in the 1960s and has since become synonymous with strength and durability. Kevlar fibers are tightly woven together to create a lightweight, flexible material that's highly resistant to cuts, tears, and impacts.
Some key features of Kevlar include:
- 5 times stronger than steel on an equal weight basis
- High tensile strength-to-weight ratio
- Excellent thermal stability
- Low electrical conductivity
What is Aramid?
Aramid is a general term for a class of synthetic fibers characterized by their exceptional strength, heat resistance, and low flammability. Aramid fibers are made from long polymer chains with strong hydrogen bonds, resulting in a material with remarkable properties. In addition to Kevlar, other aramid fiber brands include Twaron and Technora.
Aramid fibers boast impressive specs:
- Tensile strength of 3,000 to 3,620 MPa
- Decomposition temperature of 932°F (500°C)
- No melting point
- Excellent dimensional stability
Kevlar vs Aramid in Body Armor
So how do Kevlar and aramid stack up when it comes to body armor applications? Both materials excel in this area due to their high strength-to-weight ratios and ability to dissipate energy from ballistic impacts. Many body armor solutions incorporate layers of woven Kevlar or aramid fibers to create a protective barrier.
Comparison Table: | Property | Kevlar | Aramid | |----------|--------|--------| | Strength-to-weight | High | High |
| Cut resistance | Excellent | Excellent | | Heat resistance | Good | Excellent | | Flexibility | Good | Good | | Cost | High | Varies by brand |
While both perform well, aramid fibers like those used in our Tactical Scorpion Gear soft body armor may offer slightly better heat resistance. However, Kevlar remains the most well-known and trusted name in the body armor industry.
Soft Body Armor Construction
Soft body armor designed for protection against handguns and fragmentation typically uses multiple layers of woven Kevlar or aramid fabric. These layers work together to absorb and disperse energy from impacts, minimizing blunt force trauma to the wearer.
The number of layers and overall thickness of the soft armor panel can vary based on the desired level of protection. For example:
- NIJ Level IIA: at least 4 layers
- NIJ Level II: at least 6 layers
- NIJ Level IIIA: at least 8 layers
Our Caliber Armor soft body armor options demonstrate this layered construction with Kevlar and aramid materials to achieve various protection levels. The specific weave pattern and fiber properties can also influence performance.
Hard Armor Plates
For higher threat levels like rifle rounds, hard armor plates are necessary. These plates are typically made from ceramic, polyethylene, or metal and may feature a Kevlar or aramid backer for added support. The Kevlar or aramid backer helps catch any bullet fragments or spall that may come off the plate during impact.
Check out our plates and inserts collection to see how Kevlar and aramid are used in conjunction with hard armor materials for maximum protection.
Maintenance and Care
To ensure the longevity and effectiveness of your Kevlar or aramid body armor, proper maintenance is crucial. Follow these general care guidelines:
- Store armor in a cool, dry place away from direct sunlight
- Clean with a mild detergent and hang dry
- Avoid exposure to chemicals, oils, and solvents
- Inspect regularly for any signs of damage or wear
- Replace based on manufacturer recommendations, typically every 5 years
Frequently Asked Questions
Is Kevlar stronger than aramid?
Kevlar is a specific brand of aramid fiber, so its strength is comparable to other aramid materials. The strength can vary slightly between brands but in general, aramid fibers including Kevlar offer similar high strength-to-weight performance.
Can I get aramid body armor that's not Kevlar?
Yes, there are several aramid fiber options beyond DuPont Kevlar, such as Twaron and Technora. Many body armor manufacturers use a variety of aramid materials in their products. Focus on the protection level rather than a particular brand name.
How long does Kevlar body armor last?
The recommended lifespan for Kevlar and other aramid-based body armor is usually around 5 years with proper care and maintenance. However, this can vary by manufacturer and specific product, so always follow the guidelines provided by the supplier. Regular inspections can catch any wear or damage that requires replacement sooner.
