We present a shape memory composite which has repeated instant self-healing function by means of not only shape recovery but also strength recovery. The activation of the self-healing function is triggered by joule heating the embedded SMA. We demonstrate that after seven fracture/healing cycles, over 60% strength is still maintained.
