Bonded composites often cannot provide quality assurance to design specifications without nuts and bolts in addition to adhesives.
How Laser Bond Inspection Works
Using Stress Waves to Assess Composite Bond Strength
Real-time Assessment of Composite Bond Quality
By delivering precise readings of bond strength — a green light for good bonds, a red light for bad — laser bond inspection helps unleash the strength and savings of unitized components.
LBI technology measures the reflected values of laser pressure waves in real-time assessment of whether a composite adhesive bond meets design and safety requirements.

Laser Bond Inspection applies the power of high-energy, short-pulse lasers to non-destructive testing for composite adhesive bonds
With 25 years of experience in precision-controlled laser pulses, LSP Technologies uses the power of laser compressive waves to measure the strength of composite adhesive bonds — quickly evaluating whether bonded structure meet high quality standards.
With the assurance of bond integrity from Laser Bond Inspection, true unitized composite structures are possible. Look now, no bolts!
In automotive, wind power, and aerospace, the precision of Laser Bond Inspection supports weight reduction and time-efficient assembly.
How Laser Bond Inspection Works, Step by Step
Laser Bond Inspection employs laser-induced shock waves to probe composite bonds, and LBI equipment measures reflected waves to distinguish healthy bonds from weak bonds that will fail to meet quality standards and design requirements. We use a high-energy, short-pulsed laser system where we can control the energy, the pulse width and the diameter of the spot on the surface of the part.
The Laser Bond Inspection operator easily positions the inspection head over the segment of the part to be inspected.
With a small amount of water as a transparent overlay, the inspection tool delivers a short pulse of laser energy to the part.
The compressive wave propagates through the composite structure to its back wall.
As the compressive wave strikes the back side surface, it reflects as a tensile wave.
If the bond between the two materials is weak, the compressive wave will create a local disassociation at the bond interface.
The reflected wave will not damage structures with healthy adhesive bonding.
The Laser Bond Inspection tool indicates weak adhesive bonds with a red light, and the inspection tool uses a green light to indicate strong bonds.
