Main Results:

  • Achieved significant improvements in the number of healing cycles and overall healing efficiency.
  • Demonstrated superior performance compared to passive delivery methods.
  • Reduced the vascular system volume to as low as 0.1 vol% for substantial healing.

Conclusions:

  • Active pumping is a highly effective strategy for self-healing materials.
  • This method enables robust, repeatable damage repair with minimal material intrusion.
  • Nearly full recovery of fracture toughness was achieved over 15 healing cycles.
