The　fiber　push-out　test　is　a　basic　method　to　probe　the　mechanical　properties　of　the　fiber/matrix　interface　of　a　fiber-reinforced　composite.　In　this　paper,　the　interfacial　mechanical　properties　of　carbon　fiber/epoxy　composites　are　analyzed　effectively　combing　nano-indention　technique　with　cohesive　element　modeling.　Based　on　the　load-displacement　curve　obtained　from　the　nano-indention　experiments,　the　interfacial　shear　strength　is　calculated　about　13.7MPa.　Furthermore,　the　finite　element　method　(FEM)　model　of　a　fiber-reinforced　composite　is　built　in　software　ABAQUS,　in　which　cohesive　zone　model　is　chosen　to　represent　of　carbon　fiber/epoxy　composites　interface.　The　computed　results　are　consistent　with　experiment　data.　Copyright　©　(2013)　by　International　Conference　on　Fracture.
