CT inspection of armour and composite structures
BliXray CT systems inspect layered armour panels and composite structures layer by layer. Delamination, disbonds and cracks in ceramic tiles become visible without damaging the panel.

The inspection task
Armour panels and composite structures combine materials of very different density: ceramics, fibre laminates, metals and adhesives. The critical defects lie at the interfaces – a disbond between tile and backing or a delamination inside a laminate. Ultrasound finds many of them but struggles with thick, mixed stacks; CT shows every interface in the same volume.
Which system, and why
Flat, wide panels suit a gantry system: BLCT-GALAB scans long and wide parts in a horizontal layout. Thick stacks with metal backing need the penetration of BLCT-HPLAB; for the densest structures BLCT-LINACLAB works with a linear accelerator.

Questions and answers
Can CT replace ultrasonic testing?
For many panels CT complements it: ultrasound is fast on large areas, CT resolves thick, mixed stacks and shows the defect in 3D.
Can large panels be scanned?
Yes, within the part size of the system. The gantry and high-power systems take parts up to 1010 × 1980 mm.
Are results reported per layer?
Yes. Defects are located by depth and interface, so each layer can be assessed separately.
