What is the difference between kevlar and dyneema

Knowledge Kevlar VS Dyneema Rope Rope is a flexible length of material that consists of multiple braided or twisted strands. How about polyester tarpaulin? Is nylon water resistant?

What is the elastic webbing? What is Antistatic Webbing? What is Rope? What is the difference between the Dyneema and nylon? Ultra Strong Aramid Webbing What qualities make for an excellent hiking belt? What is Jacquard Webbing? What is Nomex webbing? What Is a Belt? My dad asked the officers what happens when a bullet strikes a vest. They looked a little blank. He pointed out that the strikes create friction. He then asked them what friction produced. One officer said heat and then a couple of the officers kind of chuckled.

The officers walked away from the guys both and that rep was staring at did with a look that could have burnt through lead. Dad laughed all the way back to his companies booth.

He just retired last year after about 39 years with DuPont and as far back as I can remember, he worked in Kevlar. I might be a little biased though when it comes to Kevlar vs. Thanks for the replies from people with far more knowledge than me. About to pick up a set of Kevlar OOS Any idea when they will return? Will I need anything else?

I already have the PIG molle cumberbund Email sent out about the Kevlar backers. I'll post the answer back here. Its ability to be molded to various forms allows Dyneema to be used in a variety of vehicles for military, law enforcement and civilian protection applications. Depending on the type of situations that Dyneema will be used for it can be obtained for either soft ballistics, like handguns , or hard ballistics, like antitank projectiles, land mines.

Dyneema can be used in two different ways for vehicle protection, as either spall liner or as a panel. In its form as spall liner, Dyneema works as an extra layer of protection against a ballistic threat to a vehicle. Spall liner is used to protect vehicle occupants by catching and absorbing the ballistic itself, or metal fragments that came off of the vehicle due to the explosion.

When Dyneema is used as panel it can protect against stronger ballistic threats such as antitank projectiles and tank-penetrating projectiles.

The panels can be custom shaped and easily cut to the design specifications of the vehicle. By themselves or combined Dyneema has the potential to protect against a range of ballistic threats including direct gunfire from an AK47, improvised explosive devices IEDs , rocket-propelled grenades RPGs , land mines or explosively formed penetrators EFPs. Compared to armor plating, armor made with Dyneema that has a steel or ceramic strike plate is 50 to 75 percent less dense than steel armor [source: SoldierMod.

Because it is extremely light and moldable a vehicle equipped with Dyneema doesn't have to sacrifice maneuverability or design, or change the center of gravity in order to protect against an explosion or gunfire. Dyneema has also been implemented into an invention that protects not only the occupants of a vehicle but also the vehicle itself from a direct explosion. The structural blast chimney uses Dyneema to take the initial blast of an explosion and channel it towards the center of the vehicle and then up and away from it.

The design of the chimney along with the Dyneema's impact absorption allows the vehicle stay firmly planted on the ground and intact during an explosion, protecting occupants from sound, heat and sheer force of the explosion.

Let's go on to the next page to find out how Dyneema is being used for other areas of life protection, who's using it, and how it's being used in other industries. Dyneema has other life-saving applications besides armored vehicles. Many bullet-resistant vests , boats and aircraft also use Dyneema.

South Korea's navy uses Dyneema in some of its patrol boats and hovercrafts as a way to protect them against fire and ballistic impact. The boat panels are made with Dyneema then covered with a glass epoxy resin. Because Dyneema is buoyant, it not only protects the watercraft but can also be used in marine applications like this.

Dyneema has also been implemented into airplane cockpit doors as a means of bullet resistance. After the September 11 attacks in the United States, the Federal Aviation Administration required that cockpit doors be bullet resistant. Dyneema has been used in cockpit doors ever since and now 85 percent of all aircrafts flying in the United States have cockpit doors made with Dyneema [source: Dyneema Matters ].

In addition to vehicle, marine and aircraft protection, Dyneema is also used for bullet-resistant vests and helmets. A joint initiative by the U. Army and Marines to increase helmet performance found that Dyneema could increase fragmentation performance for helmets by 35 percent or more [source: Dyneema ]. The helmets created with hard ballistic resistance from Dyneema are as strong as previous helmets made with other materials, but with half the weight.

Depending on how a bullet-resistant vest is made with Dyneema, it can withstand knives, handgun fire, armor piercing rounds, and even rifle fire from weapons like the AK
