A　low-conductivity　feature　of　carbon　fiber-reinforced　polymers　(CFRP)　needs　to　be　engineered　with　lightning　strike　protection　to　decrease　the　vulnerability　of　the　material　to　lightning　strike　damage.　This　paper　reports　a　percolating-assisted　resin　film　infusion　method　that　achieves　a　conductive　lightning　strike　protection　via　the　accumulation　of　reduced　graphene　oxide　(RGO)　on　the　composite　surface.　In　this　method,　the　fibrous　preform　was　sealed　by　the　filter　paper　and　the　sealant　tape　to　form　a　confined　region　that　avoids　the　expansion　of　RGO　from　the　fibrous　preform　while　also　limiting　the　RGO　flow　along　the　thickness　direction,　and　thus　RGO　accumulates　on　the　CFRP　surface　through　filtration　mechanisms.　The　enriched　RGO　on　CFRP　allowed　high　conductivity　values　(440　S/cm　vs.　16　S/cm　of　CFRP)　on　the　surface　while　also　improving　the　thermal　resistance　of　CFRP.　As　a　result,　RGO　protection　dramatically　improved　the　lightning　damage　resistance　as　compared　to　CFRP.　The　residual　strength,　characterized　via　3-point　flexural　testing　after　a　simulated　lightning　test,　only　decreased　by　23%　as　compared　to　its　initial　value,　whereas　a　drastic　reduction　(66%)　was　observed　for　pristine　CFRP.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
