ABSTRACT	The objective of this study is to investigate the fatigue properties of thermo-plastic composite specimens.Tested specimens were centrally circular-hole-notched and made of a carbon/thermo-plastic composite(AS-4/PEEK,APC-2)material.The mechanical properties investigated were static tensile and compressive strengths,S-N relationships for stress ratios R=0 and R=-1,fatigue life distributions,fatigue damage growth,and residual static strength after fatigue tests.Especially,fatigue life data of the long life range by the 107 cycles were collected in the fatigue life te
