Internal damage in fiber-reinforced composites, materials used in structures of modern airplanes and automobiles, is difficult to detect and nearly impossible to repair by conventional methods.
When one tiny circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss.
Researchers have found a way to pump self-healing fluids around a material similar to an animal's blood circulation.
Parachute cords, climbing ropes, and smart coatings for bridges that change color when overstressed are several possible uses for force-sensitive polymers being developed by researchers at the University of Illinois.
U.S. scientists say they are developing polymers that, when overstressed, change color -- making them ideal for applications such as bridge coatings. The force-sensitive polymers being developed at the University of Illinois contain mechanically active molecules called mechanophores.
