Non‐destructive fatigue damage detection of carbon fiber‐reinforced thermoplastics using positron annihilation method

Tensile axial fatigue tests were carried out using carbon fiber‐reinforced thermoplastics (CFRTP) plate with a hole notch up to very high cycle fatigue (VHCF) regime, where number of loading cycles was 2 × 107. The fatigue test was periodically interrupted, and fatigue damage accumulation around the...
