Carbon　fiber-reinforced　polymer　(CFRP)-confined　foam　concrete　can　be　applied　in　structure　protection,　e.g.,　as　an　impact　barrier　of　bridge　piers,　in　which　it　is　used　as　the　core　of　the　composite　impact　barrier.　Applying　CFRP　to　the　foam　concrete　exterior　enhances　both　the　CFRP　and　the　foam　concrete,　leading　to　improved　compressive　performance　due　to　their　interaction.　In　the　present　study,　the　carbon-fiber　reinforced　polymer　(CFRP)　confining　effect　on　the　response　and　energy　absorption　of　foam　concrete　subjected　to　quasi-static　and　medium-strain-rate　dynamic　compression　was　experimentally　investigated.　The　confinement　by　CFRP　changed　the　response　and　failure　mode　of　foam　concrete　specimens　from　shear　in　quasi-static　load　and　splitting　in　dynamic　load　to　crushing,　resulting　in　a　significant　increase　in　the　load　bearing　and　energy　absorption　capacity.　The　composite　consisting　of　CFRP　and　foam　concrete　was　sensitive　to　strain　rate.　In　particular,　the　CFRP-foam　concrete　interaction　led　to　the　remarkably　improved　resistance　and　energy　absorption　capacity　of　CFRP-confined　specimens,　which　were　significantly　higher　than　the　sum　of　those　of　standalone　CFRP　and　foam　concrete.
