The existing two-dimensional delamination measurement algorithms often require manual operations that make these measurements difficult to reproduce and automate. The main goal of this study is to develop a delamination-measurement method based on image differencing of the conditions before and after drilling, in order to improve the reproducibility of delamination quantification. The novel method was tested by mechanical drilling experiments in unidirectional carbon fibre reinforced polymer (UD-CFRP) composites using solid carbide tools. The developed method can measure the magnitude of drilling-induced delamination automatically.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Keywords<\/strong>: Delamination; Drilling; Digital image processing; CFRP<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Video presentation<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-video\"><video height=\"1080\" style=\"aspect-ratio: 1920 \/ 1080;\" width=\"1920\" controls src=\"https:\/\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tamas_Lukacs.mp4\"><\/video><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Presenting author<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table class=\"has-background\" style=\"background-color:#f3f4f5\"><tbody><tr><td><\/td><td><\/td><td><\/td><\/tr><tr><td><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"189\" class=\"wp-image-3939\" style=\"width: 150px;\" src=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tamas-Lukacs.jpg?resize=150%2C189&#038;ssl=1\" alt=\"\" srcset=\"https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tamas-Lukacs.jpg?w=394&amp;ssl=1 394w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tamas-Lukacs.jpg?resize=238%2C300&amp;ssl=1 238w, https:\/\/i0.wp.com\/cirpicme.org\/wp-content\/uploads\/2022\/07\/Tamas-Lukacs.jpg?resize=119%2C150&amp;ssl=1 119w\" sizes=\"auto, (max-width: 150px) 100vw, 150px\" \/><\/td><td><strong>Name:<\/strong><br><br><strong>Affiliation:<\/strong><br><br><strong>Email:<\/strong><\/td><td>Tamas Lukacs<br><br>Budapest University of Technology and Economics, Hungary<br><br>lukacs.tamas97@gmail.com<\/td><\/tr><tr><td><\/td><td><\/td><td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Tamas Lukacs, Csongor Pereszlai, Gergely Magyar, Norbert Geier (Hungary) Abstract Drilling high-strength fibrous polymer composites is challenging mainly due to their machining-induced delamination formation ability.
