Detection of Impact Defects in Laminated Composites by Holographic Interferometry

摘要

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 become 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.
