[b]You've seen it in movies: the human-like, robot assassin quickly regenerates its structure after being damaged beyond recognition. This "Terminator" scenario is becoming less far-fetched as recent advances in structural health monitoring systems have led to a variety of ways to identify damage to a structural system.[/b]
Now, in the Journal of Applied Physics, researchers at Arizona State University have created a material that may be able to not only sense damage in structural materials, such as cracking in a fiber-reinforced composite, but to even heal it. The aim of developing "autonomous adaptive structures" is to mimic the ability of biological systems such as bone to sense the presence of damage, halt its progression, and regenerate itself.
The novel autonomous material developed by Henry Sodano and colleagues uses "shape-memory" polymers with an embedded fiber-optic network that functions as both the damage detection sensor and thermal stimulus delivery system to produce a response that mimics the advanced sensory and healing traits shown in biological systems. An infrared laser transmits light through the fiber-optic system to locally heat the material, stimulating the toughening and healing mechanisms.
The material system is capable of increasing the toughness of a specimen by 11 times. After toughening the specimen, the crack can be closed using the shape-memory effect to recover an unprecedented 96 percent of the object's original strength. In fact, after the crack is closed, the new material is nearly five times as tough as the original specimen, even though it has been strained past its original failure strain point by a factor of four.
The material and healing process can be applied while the structure is in operation, which has not been possible with existing healing techniques.

a man can dream
Hah.
I think I heard about this awhile ago. Aren't they gonna make joint replacements and whatnot out of this?
That'll be awesome if they do because my family has a history of shitty bone and joint health.
And begins the horrible cyborg uprising.

The horrible invincible Cyborg uprising.
I was hoping it had become self-aware.

I hope that turns out to be the case.

Don't worry we have boulders.
Put that technology in tanks, invincible war beasts.

Holy shit, they found out about self-healing cutting mats!
Imagine the military advancements. Tanks and armor that heal themselves.

That's dumb as hell, did you even read what he posted?
It's not some sort of flash healing that occurs instantly.
Proud to be majoring in Materials Engineering.

Don't knock the idea yet. Coating a tank in a tough material that heals over time could potentially save the military a lot of money in equipment replacements.
When it comes to science, it's ok to dream. :buddy:

But it'd be super expensive, it uses fibre optics to heat the area.
On top of that, no one said it was blast resistant.

That's just what we have NOW. Considering the incredible advancement of technology in recent years, I doubt it'll be long before the military takes a significant interest in this. Imagine a tank rolling away from an ambush with what amounts to a peeling paint job, only to have it back on the field a few hours later.
Again, just because it's not that way now, doesn't mean it can't happen later.
Why would you use it on a tank anyway, they aren't really used in the front lines, and since they are tanks after all, they would use something heavy duty to take it out, and that self healing thing won't over that much more protection, and the healing won't do shit if the insides are destroyed.

Well then, what about self-healing Kevlar, or something to that effect?
Honestly, if people look at this the right way, there is limitless potential here.
Could've sworn I saw something on T.V. outlining something similar to this, but for body armor. I think it was on Future Weapons.
MAXIMUM ARMOR

And then come back 11 times stronger
So, how long until this Tech becomes compatible with organic matter? I want my darn Medkits already!
Oh wait, it actually ENHANCES the repaired material?! Well fuck me, I think we've just discovered Overheal!
