Laser Bond Inspection Solves Composite Testing Problems

Laser Bond Inspection Provides Assurance for Composite Adhesive Strength

Composites are growing in use for many advantages of weight and flexibility, and in many cases their effectiveness and safety depend on adhesive bond quality.

Manufacturing requires stringent surface preparation and consistent application and curing.

The development of Laser Bond Inspection fills a key gap, providing non-destructive testing to assure quality adhesive bond performance.

‘Laser Bond Inspection is the only known method for evaluating bond strength.’

Laser Bond Inspection

Meeting the Composite Adhesive Challenge with Non-Destructive Testing

The Challenge

Take full advantage of composite structures

  • Support innovative shapes and designs
  • Reduce manufacturing costs
  • Enhance component strength, endurance and safety

The solution

Employ tailored laser-induced high amplitude stress waves that will

  • Reveal integrity in adhesive bonds
  • Identify weak bonds

Delivering Precision

  • Control specific characteristics of the laser pulses
  • Quickly assess bond strength

Laser Bond Inspection – helping composites reach their true potential

Composite designers promise that unitized structures will provide high-strength, low-weight, and low-cost components that will outperform equivalent metal parts in cost and efficiency.

But without adequate testing to fulfill that promise, many composite parts with adhesive bonds are in fact also reinforced with nuts, bolts, and rivets. Their adhesive is treated as an environmental sealant, rather than a bonding adhesive.

It’s easy to understand the complications. Composite adhesives involve a complex set of variables in surface preparation, consistent application, and cure time, often depending on manual processes.

Laser Bond Inspection attacks these issues head on, providing non-destructive testing to composite adhesives during component production, post-assembly, and even in maintenance and overhaul operations.

With Laser Bond Inspection, the goal of verifiable quality for composite adhesive bonds is now in reach, adding new possibilities for these unitized structures.

LBI promotes use of unitized strucutre design without fasteners.
Production designers hope to replace a wide range of fastened components, LEFT, with more lightweight unitized structures, RIGHT, as long as they can guarantee strength and safety.

Only Laser Bond Inspection provides a non-destructive testing solution for composite bonds

Less expensive than conventional full-scale testing, Laser Bond Inspection provides real-time quality assurance for composite adhesive bonds during all phases of production -- even after assembly or in maintenance and repair environments. . LBI also detects kissing bonds -- composite layers touching without mechanical strength -- a key capability missing from ultrasonic testing.
