Lire la suite >An acoustical imaging technique performing 3-dimentional (3D) reconstruction and visualization of materials was developed and used to evaluate delamination cracks in textile composites. The method is based on 2-dimentional (2D) mechanical scan combined with ultrasonic A-scan to obtain 3D volumetric data. The use of focus transducer working at high frequency (20MHz) allows the imaging of curved interfaces and woven structure of the composite with high contrast and resolution. An efficient and fast algorithm was proposed and implemented for the reconstruction of surface objects from 3D volumetric data, determined by the time peak value of A-scan pulses. Such representation makes clear distinction and observation of crack defects, especially delamination, from regular pattern of the composite. 2D textile composite plate samples (20x10x2mm 3 in size) were used for the imaging before and after impact loading test. The results show in detail an internal structure of [(0°/90°)12K ,(+45°,-45°) NCF ,(-45°,+45°) NCF , (0°/90°)3K ]. The delamination fractures for samples after impact test can be precisely recognized and evaluated in their localization, size and shape.Lire moins >
