There is an interesting article on Newsmax.com about new police body armor that uses CERAMIC plates to stop RIFLE rounds!

I can understand how a steel plate can stop a bullet, and even basically understand how Kelvar stops a bullet, but how can something made of ceramic stop any bullet, let alone a rifle round like a 30-06 Armor Piercing?!?

Here's the article from Newsmax.com:

Police Confront Escalating Threats With New High-Tech Armor

Bruce Mandelblit
Thursday, May 29, 2003

Since the tragic events of Sept. 11, 2001, we all are forced to live in a new world with fresh risk and threats.

This holds especially true for those people known as “first responders.â€

The initial individuals to take action in reference to any possible terrorist incident would be our local police officers, firefighters and EMTs, and they may face anything from weapons of mass destruction to high-powered rifles.

Most law enforcement officers in the United States are issued and wear concealable soft body armor, commonly known as a “bulletproof vest,†under their uniforms. Soft body armor is a marvelous discovery, and has saved about 2,500 lives over the years.

As good as the current soft armor is, it does have its limitations, specifically against the threat of rifle rounds.

Today’s police officers, sadly, are more likely than ever to face an AK-47 or M-16 rifle used by potential terrorists, drug dealers, gang members and other assorted street thugs.

In 1986, the suspects in the notorious Miami FBI shootout used a shotgun and a rifle in their deadly battle with FBI agents.

We all remember the infamous 1997 North Hollywood bank robbery in which two heavily armed bandits, using AK-47s, fought the outgunned LAPD officers. These two bank robbers were estimated to have fired over 1,000 rounds at officers and civilians until they were finally stopped by those brave police officers.

Even more recent was the awful 2002 Washington, D.C.-area three-week shooting spree that left 10 innocent folks dead. The alleged snipers used an AR-15 rifle, a civilian version of the military M-16, to commit their horrific crimes.

It is vital to note that the soft body armor used by police officers will not stop any rounds from these high-powered rifles and, in fact, may even make the officer’s injuries worse by causing the rifle round to tumble and fragment, causing a more serious wound than if the bullet simply passed through.

In the last 10 years alone, 125 law enforcement officers died after being shot in the upper torso with rifles while wearing soft body armor.

It is obvious that a very large safety gap must be filled between the concealable soft body armor commonly worn by the average police officer and the heavy and bulky tactical vests used by SWAT teams.

Fortunately, a new product has just entered the market that fills this essential gap between soft body armor and tactical SWAT vests.

The concept is simple: a low-cost, lightweight vest, under 12 pounds and consisting of a carrier containing two 10-by-12-inch high-tech ceramic plates, designed to be worn over the officer’s basic Level II soft body armor. This vest can be put on in seconds using the “one-size-fits-all†harness and will provide up to Level IV ballistic protection (i.e., M-16, AK-47, shotgun, M-1 carbine, 30-06 AP, etc.) for the responding officer.

Because these state-of-the-art ceramic plates are designed to literally “destroy†the bullet during impact, the police officer will be able to respond virtually immediately and “stay in the fight.â€

For more information on this new high-tech ceramic plate rifle vest, please e-mail: [email protected].

My Final Thoughts: Soft body armor alone may not be sufficient protection from the hazards that today’s police officers must confront.

Given this new technology, I believe all police, deputies and other law enforcement officers and agencies should seriously consider getting these technologically advanced rifle vests into all their patrol vehicles. Those who work in higher-risk private security, such as nuclear security officers, should also ponder this advanced rifle vest.

In fact, I think this rifle vest is such an important officer safety innovation, I have decided to help market this new officer safety technology.

Police officers today have to confront new and potentially lethal threats. Everything from terrorists and gang members to drug dealers and “active shooter†situations, such as the recent Columbine disaster, are realistic daily risks that all law enforcement officers must face and defeat!

All law enforcement officers should have available to them the proper equipment, technology and training so they may do their inherently dangerous jobs in as safe as reasonably possible manner.

:uhoh: :what: :scrutiny:

Can a LEO, or anyone else, explain how these ceramic plates work to stop rifle rounds?

What will they think of next?

Thanks...
 
AllI know is, ceramics can withstand some pretty intense forces. They are used in jet engines for on compressor blades, for example. Very high RPM, temperature, etc.

So I guess these are strong enough to take the force of a rifle round without breaking.

I'm sure someone can do better than this, though.
 
'Ceramic' refers not to a single product composition, but to a whole range of human-invented non-metallic compounds.

It's like plastic - can be used to describe the material of a shopping bag, a car bumper, a gun (polymer=plastic), explosive devices, etc.

Don't associate "ceramic" in this case with examples you'd already know: ie. kitchen tiles, the nose cone of space shuttles, etc.
 
I am pretty darn sure the M1 Abrams series of tanks use ceramic armor. I am also pretty sure that they are not running around with a bunch of clay pots on the hull. The "chobham" (sp?) armor they use is a bunch of layers of steel armor and ceramic.

On a lighter note, these ceramic plates are already in use by the security forces at one of the major shopping malls in America.

(I crack me up.)
 
but how can something made of ceramic stop any bullet, let alone a rifle round like a 30-06 Armor Piercing?!?

The bullet expends almost all of its energy when shattering the ceramic plate (at least on the old ones that were only good for a few shots, newer ones are good for more), whatever's left is taken care of by the vest itself.

These are "ceramic composites" so they aren't homogenous. Maybe that means they aren't brittle like traditional ceramic materials. They're not really THAT new, but they sure are neat.

Also, if you need more than one layer, they can be duct-taped to your back.
 
Too heavy...

I would worry about excess weight from ceramic trauma plates.

If they're too heavy, the ability to use ninja climbing spikes could be severely curtailed.

I suppose the weight is comforting while taking rounds to the back while your partner assembles the take-down .300 Win Mag though...
 
Kharn is correct. The ceramic armor I have worked with absorbs the bullet energy by breaking. Then the bullet has to basically dig through the ceramic bits to reach the wearer. This severely abrades the bullet and further reduces its effectiveness by reducing its mass and sectional density.

As an aside make sure you wear these plates outside of your normal vest not inside them. The other armor is important because it redistributes the forces properly. Without it you are probably going to be shot through with a bullet and little ceramic bits it takes with it.

IIRC the armor for the Abrams is not steel and ceramic, it is steel and depleted uranium. This is why the Abrams weighs so much.
 
Where I work we use ceramic tiles to reduce abrasion and metal wear. These things are over 1" thick and come in various sizes, you'll almost wear out a diamond tile saw blade cutting them to size.
Think I'll snag a couple of used ones and take them to the range just for fun.
 
Ceramics development continues, and may reach some surprising levels.A few years back, Ford Motor Co. tested a ceramic cylinder liner, and eventually built a full ceramic four-cylinder block in their R&D department. Kinda lends new meaning to "smooth as glass" :D
 
Just musing on the use of reactive body armor as the next step. Not practical but makes for some interesting visual images.:what:
 
Not quite like crumple zones. Crumple zones work by increasing the distance work is done and therefore reduce the force (since work is constant).

Ceramics work by dissipating energy through crack propogation. When something turns from a single block into lots of little ones, a lot of new surface area is created. In creating that new surface area, energy is dissipated. You can also get a reflected shockwave through the ceramic that throws a plume of ceramic particles back at the bullet as it impacts. Its pretty cool when you see it.
 
Regardless of how ceramic plates work, this is stuff the Mall Ninja NEEDS...really NEEDS!

:D :D :D
 
Sorry. Ever seen the "magic" trick where a guy lies down and holds a cinderblock on his chest and then someone breaks that block with a big sledgehammer? The guy then stands up with little more than cinderblock dust on his chest. Its like that. The block breaks, you don't.

(Actually its the ceramic pixies that do it and throught their powerful +5 earth magic. Yeah magic. Thats the ticket... *MrAcheson wiggles fingers mysteriously.*)
 
I found this photo on the internet of a CERAMIC plate after being shot by 3 rifle rounds...amazing!

:what: :what: :what:

Ceramic Vest Plates

Very hard, very light,would probably be constructed of multiple layers as the first hit would be very distructive to the first layer(Lattice would fracture) but would dissipate the kenetic energy over a wider area but a FMJ would probably mess up your day.
Guy:cool:
 
so of course, the obvious next question is...

... how do you defeat that kinda stuff?
Would a burst of, say, .223 AP do the trick.. one to crack the shell, the others to get past? Or that new 5.7 stuff? Or som'n else?


-K
 
How do you defeat it? Well the easiest way is to shoot them in the head. The next easiest is to use an overmatching threat like a .50 bmg or explosives. If that isn't possible multiple rifle rounds in a tight group should at least help.
 
ceramic amour has been around for awhile, it was just too heavy and rigid for everyday wear. the rigidness that makes it uncomfortable is what gives it the ability to stop the rifle rounds...actually it just slows it down enough so your regular soft body armour can stop the remaining slug. it has gotten lighter and thinner over time...as has the body armour underneath

ceramic engineering has really come into it's own with it's most famous use being protecting the space shuttle from the heat of reentry.

the amour on the m-1 abrams does contain ceramic in it's "spaced armour"...spaced refers to the layering of various composites within the "boxes" of the armour panels. it stops the projectile by disipating the energy as it encounter the different layers.
