The thinning and thinning of the material when it is stretched is a consensus generally accepted by people. But the Leeds University research team has just subverted our existing understanding. The team led by Dr. DeveshMistry has just invented a new kind of synthetic material-when stretched, it will become thicker! A paper published in Nature Communications pointed out that this is one of the few materials that exhibits the characteristics of "Auxetics".
Expansion materials can expand rather than shrink when stretched in different directions.
The researchers called this peculiar material "non-porous liquid crystal elastomer". When it is stretched on a horizontal plane, it can become thicker. Unlike traditional materials such as rubber and even steel, it is not weakened by stretching, so it is very good at absorbing energy.
Research Picture-1: It is called "Liquid Crystal Elastomer"
In a statement, Dr. Mistry said: "The bulging material is outstanding in terms of energy absorption and fracture resistance. It has many potential applications, including body armor, construction, medical equipment, etc. We have submitted a patent and are Discuss the next step with the industry. "
Research map-3: Material volume conservation and microstructural strain.
Although the new material has not yet been named, its prospects are already quite exciting. Previously, the production difficulty and manufacturing cost of bulging materials have been high, but this new LCE material is easier to produce and more reliable than engineering materials.
