A Kevlar Wall Panel In One’s Home Provides Three Major Benefits:

Investing in Kevlar panels can provide high level bullet resistance for your home in a lightweight and versatile way. Kevlar is a brand name for a type of para-aramid fibers, known to provide: fantastic strength to weight ratio, chord modulus, high tenacity, limited creep and about 3.5% elongation at break.

Kevlar is often referred to as opaque armor or soft armor, due to it extreme protective abilties.

History of Bullet Proof Fabric

The full name for the material branded Kevlar is poly paraphenylene terephthalamide. It was invented by a chemist working for dupont in 1964. It actually was born out of the need for more efficient automotible tires in anticipation of a national gasoline shortage. They were attempting to create lighterweight tires with additional durability. The polymer solution was inadvertently concocted and was planned to be thrown away, but the chemist decided to test it. To the team’s amazement, they found the fibers did not break, unlike nylon. Within a few years, the property of the material was realized in what is now called Kevlar.

How Kevlar Ballistic Panels Are Made

Kevlar is created through the chemical reaction of various monomers through condensation, resulting in a liquid crastalline comportment. A mechanical process orients the polymer in an effective direction. Sulfuric acid is required in production in order to keep the water-insolube polymers combined in the solution during its synthesis. Production of the material is expensive due to the challenges related to using concerntraed sulfuric acid.

Types of Kevlar Panels

There are more than just one type of Kevlar material. It comes in a variety of material types, each with different benefits, including:

Kevlar K-29 –  found in industrial applications, such as strong cables or vehicle armor.Graph showing tenacity of kevlar compared to steel and glass

Kevlar K49 – found in important cable and rope products.

Kevlar K129 – features very high tenacity for ballistic applications, like ballistic panels.

Kevlar AP – Adds 15% higher tensile strength than K-29

Kevlar XP – lighter weight resin and KM2 plus fiber combination

Kevlar KM2 – enhanced ballistic resistance for armor applications

Risk Factors For Kevlar Wall Panels

Kevlar is highly resilient to extreme cold temperatures, even in negative 300 degrees farenheit – in fact it performs slightly better. So cold environments are no problem. Kevlar also stands up well in warm temperatures, except at the extremes (over 300 degrees) which can result in a 10% decresse of strength after 100s of hours – in other words, not damageable except in a home fire.

It is however subject to damage from ultraviolet rays, and so Kevlar for use in outdoors applications typically will include some form of sunlight protection.

Water can greatly hinder the effectiveness of Kevlar in stopping bullets. If the material becomes wet, the bonds keeping the fibers tight will be negated. This allows for a bullet to more easily push these fibers aside, thus potentially allowing a bullet to penetrate into your home. Therefore, most ballistic panels made of Kevlar will be encased in weather resistant materials.

Applications of Kevlar Bullet Resistant Material

The application most well known is its use as a protective material. It is a critical component in the personal protection in the US Army (as well as many other countries) in everything from combat helmets to ballistic vests. In helmets, the nature of the material isn’t helpful in just stopping bullets, but in helping refract them to avoid cranial injury.

It’s lightweight material make it convenient for soldier use. Kevlar panels are also used within armored vehicles and even some aircraft, to prevent spall from explosive shells. Another popular application of Kevlar is in manufacturing bomb blankets. The light nature of the material means civilians can easily carry it.

In addition to protection from bullets used by SWAT and military personnel, it is also used by firefighters for high heat resistance.

Residential Kevlar Panel Installation

Kevlar sheets can also be highly useful in residential applications. Kevlar panels can be conveniently added in to residential walls. Kevlar panels can be fitted in between the wall studs of a home. This provides high level bullet resisance.

Standard sizes can also make them great as Kevlar door panels, for providing post-production bullet resistance to an existing door.

Of course, there are some downsides to resitantial applications of Kevlar panels. While they stop bullets and knife attacks, they may not be able to prevent all forms of forced entry attackes. Their soft nature makes them susceptible to prying being pulled right out of the wall, if other reinforcement isn’t present.

Another downside, of course, is that they are opaque, so do not allow for visibility. This is fine for application within a wall, but overzealous application throughout a house can lead to limited line of sights for the occupants. A mix of properly located bullet proof glass alongside Kevlar ballistic panels can provide the best of both worlds.

Kevlar Fibers Vs Steel

To see just how strong Kevlar is, one scientist put this revolutionary material to its breaking point test. The reason this material is so strong is both thanks to its chemical structure and the way it’s manufactured. Kevlar starts out as a long, thin chain of molecules. These molecules extend and form straight parallel chains. Because of this configuration, the chains form hydrogen bonds, which act like glue. To put this to the test, a strand of Kevlar is compared to a strand of steel; though the same size, the steel is ten times the weight. The tensile testing machine used can pull the samples apart with a max force of 5.5 tons. As seen in the video above, the steel can be viewed through a high speed camera to watch exactly what happens when it breaks.

At it’s stretching apart, you can see the steel wire is being straightened out, until it abruptly snaps. The graph reveals the steel broke under 110 lbs of force.

The scientist next tests the Kevlar fabric. It behaves quite different than the steel, similar to a taught ribbon while being pulled. As it fails the fibers can be seen popping, almost one at a time – it fails in a really different way to the stainless steel. The graph shows the Kevlar doesn’t break until an impressive 440 lbs of force. Kevlar can be manufactured with such toughness that it now has 8-9 times the strength of steel of comparative weight.
