By incorporating 3D microvascular networks containing a two‐part reactive chemistry within a fiber‐reinforced composite, continuous cycles of self‐healing after interlaminar delamination are achieved. An interpenetrating vasculature shows improved in situ fluid mixing over segregated microchannels, resulting in full recovery (>100%) of mode‐I fracture resistance.
