The use of laminate carbon fibre composite materials has been growing in a substantial way in the last decade. Some industries like the aerospace, aeronautical, automotive and biomedical benefit from the introduction of new structural solutions that became possible by using these materials. However, during the life in service of the composite components the material is exposed to a great variety of external attacks. Casual impacts, heat variations and water ingestion may provoke invisible degradation that can lead to a posterior collapse. For this reason the detection of eventual defects is very important and its inspection using non-destructive techniques of primordial importance. In this paper is proposed the use of holographic interferometry techniques for non-destructive detection of defects caused by low velocity impacts in laminate carbon fibre composites.
