In　this　study,　the　fatigue　damage　modes　of　carbon　fiber/epoxy　composite　laminates　with　symmetrical　architecture　were　investigated　by　acoustic　emission　(AE)　technique　under　fully　reversed　loading.　The　principal　component　analysis　and　the　K-means　cluster　analysis　using　correlation　AE　characteristic　parameters,　including　the　energy,　the　amplitude,　and　the　duration　time,　were　performed　to　identify　various　damage　modes　during　the　fatigue　test　process.　The　analysis　results　of　the　AE　signals　indicated　that　the　high-intensity　AE　signals　were　generated　by　the　compressive　load　and　the　low-intensity　AE　signals　were　generated　by　the　tensile　load.　The　maximum　energy　and　duration　time　generated　by　the　compression　load　are　approximately　20　and　10　times　that　of　the　tensile　load,　respectively,　which　was　consistent　with　the　force-controlled　static　test　results　under　tension　and　compression　loadings.　Therefore,　the　fatigue　damage　caused　by　the　compressive　load　is　much　greater　than　that　of　tensile　load　under　fully　reversed　loading.　The　results　of　the　multi-AE　parametric　clustering　analysis　combined　with　scanning　electron　microscope　micromorphology　revealed　that　the　damage　modes　of　the　laminate　specimens　were　classified　into　five　types,　namely　matrix　cracks,　fiber/epoxy　interface　debonding,　shear,　delamination,　and　fiber　breakage.　In　addition,　the　damage　modes　at　different　stages　during　the　fatigue　test　process　were　also　analyzed　and　discussed.
