Researchers at the University of Toronto’s Faculty of Applied Science & Engineering have created an innovative class of nano-architected materials that are as strong as carbon steel yet as light as Styrofoam. Published in Advanced Materials, the research, led by Professor Tobin Filleter, highlights how machine learning was used to design nanomaterials with remarkable properties—high strength, low weight, and the ability to be customized for various applications. This breakthrough could revolutionize industries such as automotive and aerospace, where materials must balance strength and lightness.
Nano-architected materials, composed of tiny repeating units just a few hundred nanometers in size, are structured into complex 3D shapes known as nanolattices. These materials take advantage of the “smaller is stronger” principle, where nanoscale designs achieve superior strength-to-weight and stiffness-to-weight ratios compared to conventional materials. However, traditional lattice shapes often have sharp intersections and corners, creating stress concentrations that lead to premature failure.
