Ask Greg about Laser Bond Inspection for adhesive bonding of composite materials

Greg Karst, Product Line Manager for LSP Technologies, Inc.’s composites business, is attending SAMPE 2019 May 20-23 in Charlotte, North Carolina. SAMPE 2019 attracts more than 3,000 materials and process engineers, as well as exhibits of more than 250 suppliers, manufacturers and service providers.

This is the 75th anniversary of the Society for the Advancement of Material and Process Engineering (SAMPE®), a global professional member society that provides enhanced educational opportunities by delivering information on new and advanced materials and processing technology. For more information, see https://www.sampeamerica.org.

Karst manages and promotes commercial business opportunities for the Laser Bond Inspection (LBI) technologies patented by LSP Technologies. LBI is a non-destructive testing method for assessing the integrity of adhesively bonded composite materials.

The LBI method is based upon stresswave dynamics in bonded materials. LBI uses a pulsed laser system to generate a compressive stress wave on the material surface. The stresswave propagates through the material, and is reflected off the back free surface as a tensile wave. The reflected tensile wave passes through the bondline and stresses the adhesive bond at a selected strength value.

LSP Technologies’ David Sokol explains non-destructive LBI process

In a recent webinar, LSP Technologies Director of Research David Sokol explains how the company’s non-destructive Laser Bond Inspection (LBI) technology can detect faulty bonds, including kissing bonds where the materials are in contact with each other but have no structural integrity.

Adhesive seals for composite materials pose a subtle challenge for quality control and safety, and that is how to detect problematic adhesive bonding without damaging materials or the adhesive bond itself.

A key step in the LBI process is to gradually increase the fluence, or power density, measured as Joules per square centimeter, for laser beams used to measure the integrity of composite adhesive bonds.

LBI readings show shock wave shapes that either reveal integrity in composite adhesive bonds or indicate clear failure in the bonds.  The LBI process, at controlled levels, do not damage materials or compromise the integrity of healthily bonded composites.

LSP Technologies Sells Nondestructive Laser Bond Inspection System

With the recent sale of a Laser Bond Inspection (LBI) system to Northrop Grumman Corporation (NGC), LSP Technologies has achieved another milestone in the commercial integration of LBI technology.  Northrop Grumman’s implementation of LSPT’s proprietary LBI system marks another major airframe manufacturer to pursue implementing Laser Bond Inspection in their production process, further supporting Laser Bond Inspection as a reliable method for validating adhesively bonded structures.

As the aviation industry increasingly works to make aircraft lighter, safer, and more fuel-efficient, aeronautical engineers are incorporating more composite elements such as carbon fiber into their vehicle designs.  Composite airframe structures have the advantages of being lighter and more resistant to fatigue or corrosion damage than their metal counterparts.  Composite panels are joined together using adhesive bonding agents, rather than traditional rivets or fasteners, which necessitates a new inspection process to interrogate the strength and safety of the composite bonds.

CompositesWorld talks Laser Bond Inspection

CompositesWorld:  In January, David Lahrman, Vice President Business Development, highlighted Laser Bond Inspection at SME AeroDef in Long Beach, California.  Sara Black of CompositesWorld blogged about her experience at SME AeroDef including meeting our very own David Lahrman to discuss the evolving technology of LBI.  You can read the blog post here as it discusses the uses and technologies facing composites today.

She writes, “Still, if LBI could be combined with manufacturing and process controls for adhesive bonding such as those developed for the TRUST project…, we might get closer to bonded primary aerospace structure, without redundant fasteners.”
