Self-healing while being immersed in water for composite containing 7.5% microcapsules. (A) Virgin and healed fracture toughness, and (B) self-healing efficacy (mean ± sd; n = 6). Healed in humidor: Specimens were water-aged for 1 d and then fractured to measure KIC-virgin. They were then healed in a humidor in air for 1 d and then re-fractured to measure KIC-healed. Healed in water: Specimens were water-aged for 1 d and then fractured to measure KIC-virgin. They were then healed while being immersed in water for 1 d and then re-fractured to measure KIC-healed. Values with the same letter are similar (p > 0.1).
