Further advances in self-healing composite materials [Registered]

Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have created a 3D vascular system that allows for high-performance composite materials such as fiberglass to heal autonomously, and repeatedly. Internal damage in fiber-reinforced composites, materials used in structures of modern airplanes and automobiles, is difficult to detect and nearly impossible to repair by conventional methods. A small, internal crack can quickly develop into irreversible damage from delamination, a process in which the layers separate. This remains one of the most significant factors limiting more widespread use of composite materials. However, fiber-composite materials…
