Sandwich　panels　with　carbon　fiber　fabric/epoxy　resin　face-sheet　and　aluminum　foam　core　have　a　potential　application　value　in　the　engineering　field.　To　study　the　bending　mechanical　properties　of　the　reinforced　sandwich　structure,　three-point　bending　test　was　conducted　by　using　WDW-T100　electronic　universal　tensile　testing　machine.　The　relation　between　load　and　displacement　of　the　aluminum　foam　sandwich　was　obtained.　Deformations　and　failure　modes　of　the　specimens　were　recorded.　Scanning　electron　microscopy　was　used　to　observe　the　failure　mechanism.　Results　showed　that　when　aluminum　foam　was　reinforced　by　carbon　fiber　fabric　as　face-sheet,　its　flexural　load-carrying　capacity　and　energy　absorption　ability　improved　significantly.　Foam　core　density　and　number　of　carbon　fiber　plies　had　serious　impacts　on　the　peak　load　value　and　energy　absorption　value　of　the　composite　structure.　It　was　suggested　that　aluminum　foam　core　sandwich　structure　with　low　foam　core　density　of　0.49g/cm(3)　and　5　plies　of　carbon　fiber　fabric　had　the　highest　energy　absorption　ability　and　medium　load-carrying　ability.　Failure　modes　analysis　showed　that　shear　failure　leaded　to　the　final　failure　of　sandwich　panels　with　medium　peak　load　and　interface　de-bonding　leaded　to　the　final　failure　of　sandwich　panels　with　high　peak　load.
