Self-healing for the long haul: In situ automation delivers century-scale fracture recovery in structural composites

Proceedings of the National Academy of Sciences, Volume 123, Number 2, January 2026.
ImportanceDamage due to delamination has long hampered the safety and service life of fiber-reinforced polymer composites. This failure mode not only compromises their mechanical advantage in terms of lightness, but also amplifies the cost and environmental impact of these…
