Metallic Glass Could Now Be As Cheap to Produce as Plastic

metallic-glass

In 1960, the first metallic glass was developed at the California Institute of Technology. A metallic glass is an alloy that’s been heated up and then cooled down very quickly so that it doesn’t have a chance to form crystals, allowing the material to keep its amorphous structure. Thus, metallic glass is stronger than steel or titanium and just as tough, and 20 times stronger and stiffer than plastic. Metallic glass is an ideal material for everything from cellphone cases to aircraft parts.

There may now be a way to prevent such an injury. Researchers at the Fraunhofer Institute of Silicate Research have developed a sensor that can be stretched to twice its size. The sensors could be integrated into a car seat to determine the position of the occupant such as when the person is leaning over or sitting back in the seat. This would allow the force of the airbag to be lessened if the occupant is leaning forward in the event of an accident.
