Study on visual inspection of composite structures

EASA_REP_RESEA_2007_3

This study focuses on understanding the following: the composite damage metrics and the variables that influence damage detection e.g. colour, finish, lighting, cleanliness, angle at which the inspection is conducted relative to the surface. This requires consideration of the reliability of detection in relation to these variables. It may be necessary to consider metrics, other than the classic dent or assumed delamination in a no-growth test, and to exploit all variables to maximise the chances of finding damage. Reliable damage detection needs to be achieved without generating nuisance findings
