What type of testing can determine the integrity of a repaired composite structure?

The determination of the integrity of a repaired composite structure is effectively accomplished through ultrasonic testing. This testing method employs high-frequency sound waves to detect any imperfections, delaminations, or weaknesses within composite materials. By analyzing the sound waves that are reflected back from the composite structure, technicians can identify flaws that may not be visible to the naked eye or through surface inspections.

Ultrasonic testing is particularly valuable for composite structures since they can have internal defects that are critical to the strength and longevity of the repair. The non-destructive nature of this testing method allows for thorough inspections without damaging the composite materials, making it an ideal choice for verifying the integrity of repairs.

While visual inspection is important, it is limited to surface observations and cannot detect subsurface issues. Dynamic testing typically involves assessing the behavior of a structure under various loads but does not specifically target internal flaws. Moisture meter tests are useful for assessing moisture content in materials but do not directly address the structural integrity related to repairs in composites. Hence, ultrasonic testing emerges as the most comprehensive option for ensuring that a repaired composite structure is sound and safe for use.
