Damage in a carbon/epoxy plate is evaluated by enhanced X-rays. Four different drills are used. The images are analysed using Computational Vision techniques. Surface roughness is compared. Results suggest strategies for delamination reduction.engDrilling compositesDamageDelaminationComputer visionImage processingImage analysisComposite platesSurface roughnessCarbon-epoxy platesjournal article10.1504/IJMPT.2008.018983
