Researchers have created a self-healing composite that is tougher than materials currently used in aircraft wings, turbine blades and other applications—and can repair itself more than 1,000 times.

Composites have been produced for millennia. The first known use of them dates back to around 3400 BC when the Mesopotamians used glued wood strips at angles to create plywood. Other early examples ...

Composite materials are engineered by fusing different materials, typically consisting of a matrix (a polymer, metal, or ceramic) and a reinforcement (such as fibers, particles, or flakes) that ...

Mathematicians have found that they can design a range of composite materials from moiré patterns created by rotating and stretching one lattice relative to another. Their electrical and other ...
