Nanostitches for Lighter, Tougher Composite Materials

MIT engineers have shown they can prevent cracks from spreading between composite’s layers, using an approach they developed called “nanostitching,” in which they deposit chemically grown microscopic forests of carbon nanotubes between composite layers. Read on to learn more about it.

How Tough Is Your Material? 3D Images Will Tell You
