Samenvatting

The mode I delamination of a unidirectional thermoplastic composite is investigated in this work by applying Non-Destructive Techniques (NDT) like 3D Digital Image Correlation (DIC) and Acoustic Emission (AE). Using the AE data, wave features are extracted. To calculate the fracture toughness, the crack length is measured using the DIC technique and the three data reduction methods provided by ASTM D5528 are applied. All the methods resulted in the same fracture toughness values for initiation and propagation of the crack. The results of this preliminary study will be used in the future to be compared with the results of mode II delamination tests and in turn, as a basis to better understand the delamination behaviour of the considered composite material under mixed mode I/II loading.
