Boron-carbide-tshirts

Well, sort of…

A Kit Up reader sent along this fascinating article about research being done at the University of South Carolina on creating fabrics with nano structures that could increase ballistic resistance.

Check this out…

Researchers at the University of South Carolina, collaborating with others from China and Switzerland, drastically increased the toughness of a T-shirt by combining the carbon in the shirt’s cotton with boron – the third hardest material on earth. The result is a lightweight shirt reinforced with boron carbide, the same material used to protect tanks.

The scientists started with plain, white T-shirts that were cut into thin strips and dipped into a boron solution. The strips were later removed from the solution and heated in an oven. The heat changes the cotton fibers into , which react with the boron solution and produce boron carbide.

The result is a fabric that’s lightweight but tougher and stiffer than the original T-shirt, yet flexible enough that it can be bent, said Li, who led the group from USC. That flexibility is an improvement over the heavy boron-carbide plates used in bulletproof vests and body armor.

I wrote about this kind of potential for carbon nanomaterials over at Defense Tech a couple years ago. My great friend and body armor innovator David Woroner quipped that nanoscience would eventually lead to a tank that you could lift with your hand.

Of course, that's a long way off, but if manufacturing could catch up with the science, that's possible.

The cool thing about this B4C-infused T-shirt material is its potential application for flexible armor systems. Now, the story doesn't say anything about ballistic resistance, but you could see how maybe sandwiching some of this material together could yield a flexible plate.

Hat tip to CF for the gouge…

Why with China? Sleeping with the enemy? What are they thinking?

Agree with Rick. Strange choice. Cool stuff regardless.

The problem with collaborating with China on a project like this (or really any R&D project in the defense sector) is that while our government is only capable of producing a limited budget and passing that through Congress (and I acknowledge that 0.5 trillion is a lot of capital), the Chinese government has the ability to essential allocate funds to whatever it wants, whenever it wants. Furthermore, SOEs in the manufacturing sector make it possible for the Chinese government to couple this R&D with progress in manufacturing to more efficiently develop this technology for mass production. Democracy is, as Churchill said, better than all the other systems of government, but it has its deficiencies; a more centralized state has the ability to pursue long-term goals, to redirect funding with little transparency, and to manipulate the industrial and commercial sectors for its own ends. In conclusion, we should be careful who we share our R&D with (granted, we probably share a lot more than the average citizen would believe with China), because other countries might have better capabilities to expand upon those developments.

Wait, so its not a bulletproof T-shirt, its a hard strip of boron carbide made from T-Shirt scraps? The only pliability mentioned is that it 'could be bent.'

Wearing it just might feel like someone applied WAY too much starch, eh?

Still, very cool idea. Also, I agree with Rick — why China? I'm sure there are plenty of other countries that could have made a significant contribution to this project.

If this takes off, China can take it for themselves while we bicker about the implications for a few years. Apply that concept to any situation involving China, Defense, Military, or Technological Advancement and tell me if you don't get chills. Who's to say China's not already dedicating their own team to the project independently? The project flops on the US side and China turns around and sells the idea back to the states in a few years. Oops!

Proposed 28th Amendment to the United States Constitution

From: James Graham

From: S STEELE
THE HEART OF OUR PROBLEMS IS OUR POLITICANS ARE MONEY HUNGRY !!!!

As a widow of a military retiree, who stood with her husband for over 20 years while he served this country (which was the greatest in the world until this Congress and President took over), I have to say I agree. Shirley

As a retired military man that have given over twenty-seven years of my life to my country, I truly feel that what this
Country needs most is a new amendment to the Constitution . I am recommending that we add the 28th amendment to the Constitution of the UNITED STATES.

For too long we have been too complacent about the workings of Congress. Many citizens had no idea that Congress members could retire with the same pay after only one term, that they didn't pay into Social Security, that they specifically exempted themselves from many of the laws they have passed (such as being exempt from any fear of prosecution for sexual harassment) while ordinary citizens must live under those laws. The latest is to exempt themselves from the Healthcare Reform that is being considered…in all of its forms. Somehow, that doesn't seem logical. We do not have an elite that is above the law. I truly don't care if they are Democrat, Republican, Independent or whatever. The self-serving must stop.

This is a good way to do that. It is an idea whose time has come.

Proposed 28th Amendment to the United States Constitution:

"Congress shall make no law that applies to the citizens of the United States that does not apply equally to the Congressman, Senators and Representatives; and, Congress shall make no law that applies to the Congressman. Senators and Representatives that does not apply equally to the citizens of the United States".

This 28th amendment to the Constitution of the UNITED STATES Will apply to all passed, present and future
Congressman, Senators And Representatives.
Just think of all the money this would save the tax payers!!!!!

I think the Senators, Representatives or Congressman that comes out strongly for this will be our next President.

Some people got a Raise, I DID Not …

I will send this out every month until election time, just as a reminder. If everyone remembers, we can make a difference.

GRRRRRRRRRR….! I'm MAD AND YOU SHOULD BE TOO!

Your U.S. House & Senate have voted themselves $4,700

and $5,300 raises.

1. They voted to not give you a S.S. cost of living raise in
2010 and 2011.

2. Your Medicare premiums will go up $285.60 for the 2-years and you will not get the 3% COLA: $660/yr. Your total 2-yr loss and cost is -$1,600 or -$3,200 for husband and wife

3. Over 2-yrs The House & Senate each get $10,000 raises

4. Do you feel SCREWED?

5. WILL your cost of drugs – doctor fees – local taxes – food, etc., increase? You better believe they will!

WILL THEIRS…NO WAY
. They have a raise and better benefits. Why care about you? You never did anything about it in the past.
You're obviously too stupid or don't care. No offense; just making a point!

6. Do you really think that Nancy, Harry, Chris, Charlie, Barnie, et al, care about you?

SEND THE MESSAGE — You're FIRED.!!!

IN 2010 YOU WILL HAVE A CHANCE TO GET RID OF THE SITTING CONGRESS AND Up to 1/3 OF THE SENATE, AND 100% OF THE HOUSE.

MAKE SURE YOU'RE STILL MAD IN NOVEMBER 2010 AND TELL THEIR REPLACEMENTS NOT TO SCREW UP.

It is ok to forward this to your sphere of influence if you are finally tired of the abuse.
Maybe it's time for the……..

Amendment 28
"Congress shall make no law that applies to the citizens of the United
States that does not apply equally to the Senators or Representatives,
and Congress shall make no law that applies to the Senators or
Representatives that does not apply equally to the citizens of the
United States ."

Let's get this passed around, folks – these people in Washington have brought this upon themselves!!! It's time for retribution. Let's take back America.
If you don't forward this to all your friends you're just part of the problem of national apathy.

An apparently interesting story but it's not about tee shirts that are bullet proof, or even too much about the way that reporters believe that "nano " is as impressive a vogue word as "digital" used to be.

The writer is using very imprecise and obvious ploys to snare us into reading about an interesting but still rather mundane and not new use of textiles.
It's watered down pap.
Interesting to have a story that is not only too weak to do much but misses the target anyway.
It's ironic, given the fact that even if a teeshirt stopped a bullet from penetrating, the energy from the projectile would still be dispersed in a small enough area that the wearer would be disabled with a seriously caved in ribcage.

Gig April 13, 2010 at 3:40 am

Nice idea, but it's really just a novelty. Bulletproof T-shirt? Not gonna happen. Kevlar body armor works on the same principle…it's a bunch of layers sandwiched together; each layer by itself is lightweight and flexible, just like the boron carbide "cloth", but by itself won't stop a bullet, so they need to be sandwiched together. But hey, if they can get something lighter than the plates we have now while keeping or increasing the ballistic protection, why not?

Reply

Michael Z. Williamso April 13, 2010 at 4:02 am

Bullets do not "knock people down." At point blank range, a .308 will move a person a couple of inches, assuming the armor stops the bullet–there are test videos available going back 30 years of this.

Backface deformation is an issue, but it depends on the material and the projectile how much there is. If the fabric also has non-newtonian properties, it could provide some limited but effective ballistic protection.

From a strategic point of view why would we fight a war with China? We killed a million Chinese in the Korean War. And now China owns a quarter of our national debt. The Air Force may think that it could fight a war with China, but we will never fight a ground war with China for rather obvious reasons. Our army is too small to fight the Chinese, only 0.057% of the American people are in the American ground forces (Army and Marines). It simply does not matter that we are working with the Chinese to develop this fabric. We are no more likely to go to war with China than we are with Switzerland.

I believe it to be more benificial not to seclude ourselves from a potential threat and to hide in the corner playing with a chemistry set. Human knowledge belongs to the world. The implementations of this material go way beyond a bullet proof t-shirt. By being able to mass produce a nanotechnology cheaply and make it affordable, there is the potential for so many greater things that could increase the standard of living for so many. Think about when we can start making structures using the practices and discoveries form this research project. It will usher in a new era of construction and fabrications playing on the worlds most abundant resource, carbon.
If being an isolationist worked, we wouldn't be the superpower in the world that we are today.
We can't look at it as sharing potential military secrets with the enemy, have you ever been struck with a bullet in a vest? Even if the bullet can't pass through, it will still cause major damage to your internals. But the ideal of nanotech will fuel our society for the next couple hundred years!
It's like a kid spending all day building a model. The model isn't going to win first prize, but the kid who made it might end up being the engineer that invents a new building strategy.

R&D with China is counter productive… America has already given China to much of her technology. Under Bill Clinton our nuclear arsenal was compromised and China was given access to our nuclear weapons technology… among other highly sensitive items.

China is not our friend and remains a stead fast anti-capitalist state. She has no real concern with violating copyright law or stealing technology for it's own advancement.

Giving China access to research in America is foolish if not dangerous to our national security. It should be ended but will not under the present adminsitration… or Congressional leadership.

Sweet concept that could lead to better body armor down the line. The idea behind this is to one day have body armor that is very flexible and can also stop high caliber rounds and shrapnal.

If china fought now like they did back in the korean war, with human wave attacks, u.s. Soldiers would just use the m134 and obliterate them. I think we could win a war with china becase we would model our stragety basically off of the gulf war and iraq stragety, gain air superiority and then bomb the hell outta them untill they are too weak to repell a ground attack. All it takes is to compare our military training, equipment, and leadership to the chineses and see that even though they have more troops, ours are better trained and better equiped.

Adam,

It seems like anytime that someone urges caution when doing business with China, they're immediately tagged as either "Isolationist" or "Protectionist." "Free Trade" doesn't mean that you have to be a sucker, or should put up with your national economy being raped. We may be doing business with China, but thinking that China is our friend is like playing Three-Card-Monte and believing the dealer is on your side!

For the comments about going to war with China, why would China want to go to war with us when our government will gladly sell off our strategic interests (Long Beach Naval Shipyard), and our citizens can't wait to sell their children into economic slavery to save a few cents at Wal-Mart?

I understand the trepidation about working with the Qin.

China, is critical at this stage of evolution due to its manufacturing over 60% of the daily use products for the USA. It would be best to make China our ally, as opposed to Russia, or France.

They have human rights issues, but that is not our problem. What about all the issues with Africa? No one cares. Africans produce nothing, and if they had no oil, the world would turn its back on Africa.

Think Globally, because its better to be allies with the big dogs, even if they bite occassionally.

1. Boron compounds are highly toxic.
2. The manufacture of Boron-Graphite rods was ended due to that fact.
3. In the 1980s I worked on Engineered Composite Materials and we abandoned the Boron materials.
4. With that in mind, what of the material shed due to high velocity impact, is it inhaled, forced into the tissue or carried deep into the body if penetration occurs does it pose a health hazard to those who wear it much less those that manufacture it?
5. We need to look at ways to encapsulate or bind these materials so that they don't do by toxic effect what the bullet failed to.

Just a coupla comments about the shirt that could actually make it something usable:
1. If this material is actually able to prevent a bullet (need to figure out calibers it can stop) from penatrating then you could use a light weight polycarbonite (aka F-117 is made from some incredibly strong plastic) inserts to diffuse and absorb the impact.
2. As far as the health risks associated with inhalation of microscopic tissues after impact… you could enclose the material in gel like material that has a rubber or t-shirt skin on the outside.
Of course, this is all a moot point if the material isn't actually capable of resisting a bullet from penatrating. But if it is, a bullet resistant vest could go from the current 20-25lbs to 1-2lbs. Thats a step in the right direction from my view.

As Norman pointed out Boron is highly toxic and hazardous. Boron fibers are like very strong miniature needles. If handled they can bore right through the skin, break off travel through the circulatory system reeking major havoc on the human body. Manufactures following even strict handling protocols have had cases of Boron related injuries. Once this stuff is in your system good luck getting it out. A famous line from Flight Director Gene Kranz during the Apollo 13 emergency, "Let's work the problem people. Let's not make things worse by guessing." could equally apply here. Using a material just because it is strong without considering the long term health damage may ultimately make the problem much worse. Involving the Chinese in this research is industrial strength stupid. What's wrong people, haven't we had enough with antifreeze tainted pet food and lead painted children's toys? Do we really want to give our military something that will slowly kill them as well?

Sounds like a plan! But my concern is "impact trauma"! If the T-shirt is effective in displacing the impact, then it will definitely save lives. If not, the mere impact would create just as much lethal damage as the round would by penetrating the T-Shirt and the military man/woman. Just how can this challenge be neutralized to the point of survivability???? That one thing worries the be-Jesus out of me!
