Laser Bond Inspection System

Non-Destructive Inspection for Bonded Structures

Laser Bond Inspection (LBI) is a nondestructive inspection method for evaluating adhesive bond strength in composite structures. LBI uses a pulsed laser system to generate a controlled stress wave which proof-tests an adhesive bond.

Laser Bond Inspection Process

Laser Bond Inspection is a precision inspection method with high process control. The laser can be calibrated to generate tailored stress waves at selected strength thresholds. These stress waves produce detectable dissociations in weak or substandard bonds, while having no effect on sufficiently strong bonds.

Laser Bond Inspection System

Laser Bond Inspection can be used to develop and evaluate manufacturing processes, and to monitor bond integrity throughout the life of a structure. This NDT method provides controlled, localized structural health monitoring for a wide variety of bonded composite structures. There exists no equivalent laser system in the commercial sector.

LBI Applications

  • Conduct nondestructive inspections in production environments or in the field.
  • Conduct calibrated dynamic strength measurements to identify bondline weaknesses.
  • Identify weak bonds resulting from improper surface preparation or contamination.
  • Identify variations in bond strength across a structure.
  • Identify kissing bonds.
  • Assess damage resistance of bonded composite structures.
  • Evaluate coating adhesion.
