Needled　C/SiC　composites　are　widely　used　in　the　aerospace　field,　making　the　evaluation　of　fatigue　damage　critically　important.　A　fatigue　damage　model　associated　with　the　individual　modulus　is　proposed.　Compared　to　the　fatigue　damage　model　by　S-N　curve,　the　proposed　fatigue　damage　model　can　better　characterize　the　fatigue　damage　behavior　of　UN-C/SiC　composites.　By　combining　the　rainflow　counting　method,　the　Goodman　equation,　and　the　Palmgren-Miner　damage　accumulation　rule,　a　fatigue　life　prediction　method　considering　the　individual　modulus　is　developed　for　UN-C/SiC　composites　under　variable　amplitude　loading.　Compared　with　the　experimental　life,　the　predicted　fatigue　life　shows　a　good　result.
