Lou, not quite yet--at least, not until composites look like molten silver and get personalities.

Mydesign, thanks for your comments. I agree that this breakthrough may be a very important one for planes and cars, as well as spacecraft.

SELF-HEALING GRADE COMPOSITES

This is a HUGE breakthrough in composite structures.  Very innovative and creative application of engineering and materials technology.  I have a little experience in repairing fiberglass boats and can state unequivocally --I'm TERRIBLE.  It's a real pain and even if successful, the repair looks awful!   It looks like a patch.  The methodology you describe could certainly provide needed solutions to composite materials.  It seems the repair is every bit as durable as the original material if not more so. I love hearing that, in some cases at least, our tax $$$$$$$ are used for efforts that provide value-added to components and structures.   Excellent post.  Really appreciate the continued updates relative to composites.

Ann, doesn't this remind you of the Terminator movies.  Scarry, isn't it?

"one of the biggest obstacles to greater use of fiber-reinforced composites in automotive and aerospace structures is the difficulty of detecting internal damage that can quickly propagate and cause delamination problems."

Ann, self healing process is bit complicated in machines. In human self healing mechanisms works well because of the running blood and healing contents inside the blood. But in machines, its bit difficult because of the constituted participles, but to an extent now researchers are confident that machines can also be in self healing process. Hope this will be good for space, avionic and remotely controlled machines.

A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
