  • Recap: CAMX 2017

    by Emily Walsh December 2017

    Last week, BTG Labs exhibited and presented at the largest composites show and conference: CAMX 2017. Despite a set-back due to Hurricane Irma, causing the date to be rescheduled from September to December, the show attracted a large turn out with hundreds of industry specialists to exchange the latest in composite innovation.

    As manufacturers of the fast, easy, accurate, and hand-held Surface Analyst that is used widely in the composites industry, CAMX is a show that BTG Labs anticipates every year.

    BTG Labs Sales Engineer Paul McLean, who hosted a booth alongside Sales Engineer Alex Bien, reflects on the event: …Read More

  • As the wind energy industry grows—by 2020 it is expected to provide 10% of the nation’s electricity— wind turbine manufacturers must strive for the most reliable and efficient product that operates reliably and seamlessly. Adhesion failures in the field, are unacceptable and even dangerous, but still occur.

    Wind turbine manufacturers are making it a priority to overcome adhesion failures in the field and implement ways to ensure repairs only need to be done once. Currently, wind turbine repair is extremely expensive: in most cases, the part must be shipped back to the manufacturing plant for repair. And most importantly, turbine failure could be damaging and dangerous to what could be in the vicinity.

    Adhesion failures most often happen due to improper surface treatment prior to adhesion. Optimizing adhesion processes and gaining control of the bond surface guarantees a reliable bond and prevents failures in the field.

    As a result, wind turbine manufacturers are turning to the best in surface cleanliness gauges: The Surface Analyst.

  • Next week, BTG Labs will exhibit and present at SPE ACCE (Society of Plastics Engineers Automotive Composites Conference and Exhibition) the world’s leading automotive composites forum. Over 800 speakers, exhibitors, and attendees from around the world will gather in Novi, Michigan September 6-8 to share the latest in thermoset and thermoplastic composites for automotive manufacturing.

    BTG Labs Lead Sales Engineer Lucas Dillingham will present “Understanding Surface Energy: How to Measure and Control the Surface Properties of Thermoplastics to Maximize Adhesion.” As the use of thermoplastics in automotive manufacturing increases, the challenges of bonding this low energy surface must be overcome.

    Lucas will discuss surface characteristics of thermoplastics and how to use that knowledge to create and control a surface that is ready to bond reliably.

  • SAMPE is the “Society of Advancement of Materials and Process Engineering,” and annually they host a conference and exhibit hall where Scientists and Engineers gather to learn about the past year’s manufacturing advancements. Giles Dillingham, our Chief Scientist and CEO, has been a member for 15 years, and BTG Labs has presented many different technical papers and research projects at this conference. This was my second time attending this conference, after last year in Long Beach.

    While SAMPE targets the advancement of all materials and processes, composites—namely carbon fiber—dominate the show. Many exhibitors manufacture woven carbon fiber materials that will be turned into aircraft structures or interiors. Other vendors supply OEM aircraft manufacturers and tier 1 suppliers, specific parts that will be installed directly onto final products.

    Some examples include specialized composite tubing and fluid tanks for waste and water storage. I also saw: tooling manufacturers, adhesive and tape suppliers, software companies, testing labs, autoclave/oven vendors (one was giving virtual reality tours of their equipment!), and material processing equipment. This included 4 plasma treatment companies. The most we have seen at SAMPE to date. …Read More

  • The utilization of composites increases daily in manufacturing as more ways in which to use this advanced material are discovered. Composite is a smart material that provides a lighter weight and stronger product. This advanced material is being used in many different industries, from consumer products like bicycle frames to airplanes. Yet, because the strength is held in the fibrous matrix of the material, composites must be adhesively bonded together as traditional mechanical fasteners can break the fibers and compromise the material’s integrity.

    To guarantee these bonds, BTG Labs’ Surface Analyst™ precisely, accurately, and quantifiably measures the surface’s readiness to bond. BTG Labs’ experience in the field of composites reaches back to the genesis of the Surface Analyst when the USAF turned to the company to engineer a hand-held surface energy measurement device for composite bonding of aircraft. Since then, the Surface Analyst’s composite applications continue to increase and span into many more industries.

    Surface Analyst Applications Examples for Bonding, Coating, Sealing, and Painting Composites

    • Aerospace: satellites, aircraft, and spacecraft
    • Sports and Recreation: sporting equipment
    • Automotive: structural components, drive shafts, interior parts
    • Medical Device: prosthetics, repair equipment, tubing
    • Marine: structural frames and components, fiber glass applications
    • Renewable energy: wind turbines, fuel cells, marine turbines, power transmissions, solar panels
    • Construction: architectural, fiberglass, bridges, infrastructure, housing, refurbishing

  • Consumer Goods

    Golf BallThe world of consumer goods is highly diverse so consequently, manufacturing processes are even more varied. From golf clubs to paints to windows to solar panels, consumer goods products face a variety of stresses in the field that can include moisture, impact, contaminants, and environmental stresses. Manufacturers must produce a product to withstand those stresses. BTG Labs’ Surface Analyst™ can do just that. It is a versatile, handheld, accurate, easy to use instrument that can cut down on failure and waste and ensure surfaces are properly prepared to create the strongest bonds whether its coating, printing, painting, sealing, or cleaning. The Surface Analyst measures, monitors, and guarantees from the lab to the factory floor.

  • Mechanical testing of the bond surface on an adhesive joint.

    Mechanical testing of the bond surface on an adhesive joint.

    BTG Labs recently hosted another successful webinar through Composites World Magazine. The webinar, presented by BTG Labs’ CEO and Chief Scientist Dr. Giles Dillingham, entitled “Understanding and Controlling the Bond Surface in Manufacturing for Reliable Adhesive Bonds of Composites” drew over 580 registrants.

    In the presentation, Dr. Dillingham details the benefits of using adhesive bonds in composite manufacturing and repairs and ways to ensure the success of those bonds. The use of composite materials in manufacturing is increasing as composites provide a stronger and lighter material. However, because of their structure, mechanical fasteners compromise the material strength of the composite. Thus, adhesive bonds provide the most successful way in which to bond composites. To ensure the success of an adhesive bond, certain surface preparation methods must be in place. Consequently, the strength of a bond depends on the surface energy of the bond surface. The webinar discusses characteristics of a successful bond surface and different preparation methods to attain that desired surface.

  • Progress in the Reliability of Bonded Composite Structures


    Improving Composite Bonds in Aircraft


    The Surface Analyst™ technology has many of its roots in the CAI (Composites Affordability Initiative) program from the mid to late 1990’s.  This industry/government partnership comprised of a team charged with addressing the perceived risks and barriers to a more widespread use of composite materials in aircraft design. The collaboration included members from the Air Force Materials Laboratory, the Office of Naval Research, Bell Helicopter Textron, The Boeing Company, Lockheed Martin Corporation, and Northrop Grumman Corporation.
