    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.

  • BTG Labs Collaborates with Abaris to Present Webinar


    Giles Dillingham of BTG Labs recently  presented a webinar with Louis Dorworth of Abaris. Hosted by Composites World Magazine, this webinar discussed surface energy measurements on composites. The presentation entitled “Measuring Surface Energy in Manufacturing and Repair of Composites to Assure Quality of Bonded Interfaces” brought over 550 registrants.

    Abaris and BTG Labs Webinar

    In this webinar, Abaris provided their years of expertise in advanced composite training and consultation services. Abaris continues to inform and educate on the latest composite manufacturing processes. They offer 26 different composite courses in engineering, manufacturing, and repair related topics.

    Some topics included the description of basic bonding requirements of composites, goals of surface preparation, things to avoid when preparing composite surfaces, and varying surface preparation methods. They discussed measuring surface energy when repairing composites. Hence, controlling and measuring surface energy can cut down on repair time and reduce future failures. The webinar also delves in to the descriptions and effects of different treatments such as abrasion, flame, and plasma treatment.
