Fatigue tests have been conducted on impact damaged coupons of T300/914 carbon-fibre-reinforced plastic. Two damage levels were used to represent BVID (barely visible impact damage) and VID (visible impact damage). Fatigue tests were conducted at a frequency of 5 Hz and a load ratio of R = -1. Progression of fatigue damage was monitored by ultrasonic C-scan, measurement of changes in the coupon modulus and measurement of hysteresis in the impact damaged coupons.
