Therefore, availability of a tool able to check the optical fibre sensor-composite interaction becomes essential. High-resolution 3D X-ray Micro-Computed Tomography, or Micro-CT, is a relatively new non-destructive inspection technique which enables investigations of the internal structure of a sample without actually compromising its integrity. In this work the feasibility of inspecting the position, the orientation and, more generally, the quality of the embedment of an optical fibre sensor in a carbon fibre reinforced laminate at unit cell level have been proven.<\/jats:p>","DOI":"10.3390\/s150510852","type":"journal-article","created":{"date-parts":[[2015,5,7]],"date-time":"2015-05-07T14:54:29Z","timestamp":1431010469000},"page":"10852-10871","source":"Crossref","is-referenced-by-count":15,"title":["A Micro-Computed Tomography Technique to Study the Quality of Fibre Optics Embedded in Composite Materials"],"prefix":"10.3390","volume":"15","author":[{"given":"Gabriele","family":"Chiesura","sequence":"first","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Geert","family":"Luyckx","sequence":"additional","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Eli","family":"Voet","sequence":"additional","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Nicolas","family":"Lammens","sequence":"additional","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Wim","family":"Van Paepegem","sequence":"additional","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Joris","family":"Degrieck","sequence":"additional","affiliation":[{"name":"Department of Material Science and Engineering, Ghent University, Technologiepark 903, 9052 Gent-Zwijnaarde, Belgium"}]},{"given":"Manuel","family":"Dierick","sequence":"additional","affiliation":[{"name":"UGCT\u2014Department of Physics and Astronomy, Ghent University, Proeftuinstraat 86, 9000 Ghent, Belgium"}]},{"given":"Luc","family":"Van Hoorebeke","sequence":"additional","affiliation":[{"name":"UGCT\u2014Department of Physics and Astronomy, Ghent University, Proeftuinstraat 86, 9000 Ghent, Belgium"}]},{"given":"Pieter","family":"Vanderniepen","sequence":"additional","affiliation":[{"name":"UGCT\u2014Department of Physics and Astronomy, Ghent University, Proeftuinstraat 86, 9000 Ghent, Belgium"}]},{"given":"Sanne","family":"Sulejmani","sequence":"additional","affiliation":[{"name":"Brussels Photonics Team (B-PHOT), Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussel, Belgium"}]},{"given":"Camille","family":"Sonnenfeld","sequence":"additional","affiliation":[{"name":"Brussels Photonics Team (B-PHOT), Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussel, Belgium"}]},{"given":"Thomas","family":"Geernaert","sequence":"additional","affiliation":[{"name":"Brussels Photonics Team (B-PHOT), Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussel, Belgium"}]},{"given":"Francis","family":"Berghmans","sequence":"additional","affiliation":[{"name":"Brussels Photonics Team (B-PHOT), Vrije Universiteit Brussel, Pleinlaan 2, B-1050 Brussel, Belgium"}]}],"member":"1968","published-online":{"date-parts":[[2015,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"384","DOI":"10.3390\/s110100384","article-title":"Strain Measurements of Composite Laminates with Embedded Fibre Bragg Gratings: Criticism and Opportunities for Research","volume":"11","author":"Luyckx","year":"2011","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3687","DOI":"10.3390\/s110403687","article-title":"Fiber Optic Sensors for Structural Health Monitoring of Air Platforms","volume":"11","author":"Guo","year":"2011","journal-title":"Sensors"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"7394","DOI":"10.3390\/s140407394","article-title":"Fiber Bragg Grating Sensors toward Structural Health Monitoring in Composite Materials: Challenges and Solutions","volume":"14","author":"Kinet","year":"2014","journal-title":"Sensors"},{"key":"ref_4","unstructured":"Parlevliet, P., Voet, E., Bersee, H., and Beukers, A.
