ABSTRACT	The flexural fatigue behavixperimentally evaluated,with flexural fatigue strength results indicating that IMS and HS cross-ply CFRP laminates are effected more by the shape and generally have a greater S-N(stress amplitude versus number of cycles to failure)curves in the slope than MS ones.After being subjected to 107 cylces,the resultant ratio of flexural fatigue strength to static flexural strength was found to be 0.50,0.42,and 0.40 for MS,IMS and HS cross-ply CFRP laminates,respectively.
