From t he pap ers on t he invest igation of t hese f our sections, it is found th at many fat igu e damage evolut ion equat ion s and lif e prediction methods have been present ed on fatigue reliabilit y of composit e material. Whereas t here is a lot of w ork t o do in t he research fields of t he equivalent damage principle of composit es t o draw up t he load and condition spectrum, fatigue reliabilit y b ehavior , fat igue reliability lif e predict ion under act ural load spect rum and t he inf init e lif e reliability design Key words: composit e mat erial; fat igue reliability; load and condit io n spectrun; f at igue behavior , l if e pred
