Robotic CT Pushes Boundaries for Inspecting Complex Composite Structures

Why It Matters

The capability to non‑destructively inspect large, intricate composite structures accelerates certification and reduces costly rework in aerospace, defence and energy sectors.

Key Takeaways

• Robotic CT now scans three‑metre carbon‑fibre components
• Two‑micron resolution reveals internal bondline defects
• Computed laminography targets specific regions, saving time
• UR20 cobot increases payload and detector size capacity

Pulse Analysis

The surge in high‑performance composite materials across aerospace, defence and renewable energy has outpaced traditional non‑destructive evaluation (NDE) methods. Conventional ultrasonic or X‑ray techniques struggle with deep‑buried bondlines, diagonal splices, and thick laminates, creating bottlenecks in quality assurance and certification. By integrating a collaborative UR20 robot with a powerful 130 kV X‑ray source and a large‑area detector, Omni NDE’s upgraded Robot CT delivers unprecedented scan volume and resolution, effectively bridging the gap between material complexity and inspection capability.

Beyond sheer size, the system’s real‑time Iris software and 4K monitoring provide operators with immediate feedback, enabling dynamic parameter tweaks during scans. This level of control reduces the risk of missed defects and shortens inspection cycles, especially when combined with computed laminography. Unlike full‑component CT, laminography isolates regions of interest, delivering high‑resolution data for critical features such as honeycomb core splices or "kissing" bonds without the time penalty of scanning entire assemblies. The result is a more efficient workflow that aligns with lean manufacturing principles while maintaining rigorous safety standards.

Industry analysts view robotic CT as a catalyst for next‑generation composite certification. Its ability to visualize internal anomalies—voids, porosity, foreign‑object debris—with two‑micron precision supports early defect detection, lowering warranty costs and enhancing product reliability. As regulatory bodies tighten inspection requirements for larger, more integrated structures, the adoption of automated, high‑resolution CT platforms is likely to become a competitive differentiator for manufacturers seeking to accelerate time‑to‑market while safeguarding structural integrity.
