Scientists Develop New “Unbreakable Glass” Inspired by Nature — 3x Stronger, 5x More Fracture-Resistant

Posted by in categories: bioengineering, materials

Strongest and toughest glass known developed by McGill University scientists.

Scientists from McGill University develop stronger and tougher glass, inspired by the inner layer of mollusk shells. Instead of shattering upon impact, the new material has the resiliency of plastic and could be used to improve cell phone screens in the future, among other applications.

While techniques like tempering and laminating can help reinforce glass, they are costly and no longer work once the surface is damaged. “Until now there were trade-offs between high strength, toughness, and transparency. Our new material is not only three times stronger than the normal glass, but also more than five times more fracture-resistant,” says Allen Ehrlicher, an Associate Professor in the Department of Bioengineering at McGill University.
