Damage Development in Notched Carbon Fibre Composites Subjected to Fatigue Loadinggue loading (R = ?1). Fatigue data were obtained in the form of an S—N curve. Fatigue damage development was studied using C-scan, X-ray radiography, optical microscopy and deply. The damage processes under fatigue loading were described and the effect upon residual performance assessed.
