Paper Abstract

The paper describes theoretical and experimental results of the inspection of 5 mm- and 15 mm-thick filament wound CFRP shell samples containing Teflon inserts as defect surrogates. Heating was accomplished with a 30 kW tubular quartz lamp heater which provided up to 14 kW/m2 of absorbed power. Thermal properties of the samples were evaluated including the analysis of diffusivity anisotropy. Both one- and two-sided test procedures were comparatively investigated to illustrate difficulties which appeared in the inspection of thick composites.
