About This Quiz
Dyneema is trademarked as the world's strongest fiber and is used for a wide variety of applications, especially in life-threatening situations. Think you know how strong Dyneema is and how it works? Then take the ultimate Dyneema quiz!
Dyneema is a synthetic fiber made from a certain chemical similar to the one used in many plastics -- one with an ultra-high molecular weight. What is the chemical?
Ethylene
Polyethylene
Polyethylene is used to make many plastics, but only the ultra-high molecular weight polyethylene (UHMW-PE) will produce Dyneema.
Polycarbonite

Dyneema's strong chemical composition allows it to boast of many characteristics. Which of the following is NOT a characteristic of Dyneema?
Lighter than air
Although Dyneema can float on water, is fire resistant and self-extinguishing it is not lighter than air. It is lightweight, however, and yet it can still stop a bullet from an AK47.
Floats on water
Fire resistant and self-extinguishing

Dyneema is a synthetic fiber that's biologically what?
Inert
Dyneema is biologically inert so it doesn't cause any negative reactions from the human body when someone touches it.
Toxic
Sustainable

Dyneema is trademarked as the world's strongest fiber. But how strong is it compared to steel?
5 times stronger
10 times stronger
15 times stronger
Maybe they should rename Superman as the "Man of Dyneema" because this fiber is 15 times stronger than steel!

Dyneema can be made as a continuous filament yarn for things like ropes. What else is this form of Dyneema currently being used for?
Tight-rope walking ropes
Pull-start lawnmower cords
Fishing nets
Holy mackerel! Dyneema is currently used for high-strength fishing nets.

In order to absorb ballistic impacts more efficiently, Dyneema fibers can be stacked in unidirectional layers on top of each other at what angle?
30 degrees
60 degrees
90 degrees
Dyneema unidirectional sheets are layered on top of each other at a 90 degree angle in order to disperse the energy of an impact faster and more efficiently.

Not all bullet-resistant materials protect against every kind of threat. What type of ballistics does Dyneema protect against?
Soft ballistics like handguns
Hard ballistics like antitank projectiles
Both soft and hard ballistics
Although Dyneema can't stop every kind of threat, it can protect against both soft and hard ballistics.

Sheets of Dyneema can be added on the inside of a vehicle to protect occupants against small fragments after an explosion. What is the name of this type of added protection?
Spall liner
Spall are tiny pieces of metal, concrete or other projectiles that can penetrate a vehicle after an explosion. Spall liners are used to catch and absorb these fragments so they don't injure vehicle occupants.
Blast liner
Eye liner

In order to protect from high impact threats, Dyneema can easily be cut into specifically designed panels. What's one main way these panels are being used?
Hurricane-resistant houses
Armored vehicles
Dyneema can be shaped and cut easily which makes it an ideal material for armored vehicles that need high-impact protection.

Not only is Dyneema extremely strong, but it's also lightweight and not very dense. Compared to a steel plate of armor, Dyneema is what percentage less dense?
20 to 30 percent less dense
50 to 75 percent less dense
Dyneema can be 50 to 75 percent less dense than steel armor even when it has a steel or ceramic strike plate on it. That means there's a lot less weight on a person or vehicle!
100 to 125 percent less dense

Dyneema's light weight makes it ideal for vehicles because they can be protected without sacrificing what?
Maneuverability
Original design
All of the above
Dyneema's lightweight characteristic doesn't sacrifice a vehicle's design or maneuverability. Other armored vehicle options are heavier and can impact a vehicles ability to perform, throw off the center of gravity or inhibit their original design.

Dyneema is an innovation in and of itself, but it's also being implemented into other innovations like the structural blast chimney, which does what?
Channels the energy of an explosion back toward where the explosion first occurred.
Channels the energy of an explosion to the center of the vehicle then up and away from it.
The Structural Blast Chimney channels the energy from an explosion to the center of the vehicle and then sends it up and away from the vehicle. This allows the vehicle to stay firmly planted on the ground while protecting the occupants as well.
Channels the energy of an explosion down into the ground.

After the attacks on the United States on September 11, 2001, the Federal Aviation Administration (FAA) said that all cockpit doors must be bullet-resistant. What percentage of aircraft in the United States have bullet-resistant doors made out of Dyneema?
25 percent
50 percent
85 percent
85 percent of all aircraft flying in the United States have bullet-resistant cockpit doors made out of Dyneema.

Police SWAT teams often use helmets in their tactical operations. Helmets made with Dyneema provide the same protection as previous helmets but with what extra benefit?
The helmets are half the weight
SWAT helmets made with Dyneema are half the weight of previous helmets. This provides officers with added maneuverability and less equipment weight.
