The　fatigue　loading　parameter-life　(S　-N)　curve　of　the　needled　composite　was　proposed　by　constant　amplitude　fatigue　tests　first,　and　then　the　variable　amplitude　fatigue　tests　of　needled　C/SiC　ceramic　matrix　composite　were　completed.　Combined　with　the　rainflow　counting　method,　the　Goodman　line,　the　constant　amplitude　S　-N　curve　and　the　linear　damage　accumulation　rule,　the　fatigue　life　of　the　needled　C/SiC　composite　was　predicted　under　tensile　variable　amplitude　block　loading.　According　to　the　ratio　of　the　width　containing　needled　fiber　bundle　to　the　specimen　width,　the　influence　of　needled　fiber　bundle　on　the　fatigue　life　dispersion　was　quantitatively　analyzed　for　the　specimens　with　different　fatigue　lives.
