Performing fatigue experiments on all these combinations of fiber–matrix composites up to 10<sup>9</sup> cycles to mimic their typical lifetime of 15–20 years, at a low testing frequency generally in the range of 5–10 Hz in applications such as the aerospace industry, is expensive and time-consuming. In this study, a test system to investigate the very high cycle fatigue (VHCF) behavior of continuous fiber-reinforced polymers under an axial loading (tension–compression) condition is proposed. To do so, a testing system capable of applying cyclic oscillations at a frequency of 20 kHz and stress ratio, R = -1 was developed. For this investigation, the carbon fiber reinforced in Polyether-ketone-ketone (CF-PEKK) material was chosen. For visualization of the specimen oscillation-mode at 20 kHz, video-imaging using a high-speed camera (HSC) was employed.
