Abstract

An apparatus for examining components comprising laid fiber composite fabrics or woven fiber composite fabrics which comprise a number of thin plies with in part different alignment, comprises a measuring device for carrying out a non-destructive measurement to collect volumetric data of the component and comprising an evaluation device for evaluating the collected data of the component, wherein the evaluation by the evaluation device comprises selecting a first analysis region in the collected data of the component, determining a local coordinate system of the first analysis region, successively establishing local material properties layer-by-layer at predetermined distances in a direction perpendicular to the lateral extent of the first analysis region, detecting ply boundaries along the established material properties, and averaging the local material properties in each detected ply.
