  • Welcome to the BTG Labs Materials Library series.

    In this series, we use the Surface Analyst to demonstrate how the surface quality of a material changes based on common surface preparation processes. We also give typical contact angle measurements before and after processing, to give a general reference for each process as it pertains to the material.

    This video demonstrates how the Surface Analyst gives you the ability to measure changes in composite preparation through treatment using atmospheric plasma. These measurements are used to develop, verify, and monitor surface preparation processes in manufacturing.

    Whether you’re using the Surface Analyst in the lab, or in the hands of an operator on the factory floor, the Surface Analyst give you real-time business insights while dramatically improving quality control.

  • Successful adhesive bonding requires precise control of the physical and chemical properties of a vanishingly small volume of material: the first few molecular layers that surround the interface.

    This requires developing a sensitivity to the factors that affect this region by imposing effective process control protocols.

    This webinar will review the requirements for high-performance surface treatment processes, strategies for developing these processes for new material systems, and protocols for control of these processes after implementation in manufacturing.

    Primary Topics:
    • Basic principles of adhesive bonding for joining composite structures
    • Common composite surface preparation methods, their advantages and disadvantages
    • Development of surface treatment processes: how to evaluate and optimize performance
    • Deployment of adhesive bonding processes in manufacturing: how to ensure control to achieve consistent bond performance

  • In the early 2000s, the U.S. Airforce recruited BTG Labs to aid in the development of bonding technologies for composite materials to replace heavier aluminum and titanium in aircraft manufacturing. Carbon fiber composites provide lighter, stronger options for aircraft materials. But, to realize these advantages composites must attach by bonding, not by mechanical fasteners. The primary obstacle to bonding has been the lack of a practical way to inspect a bond surface and ensure that they have been prepared in a way that will produce a strong, reliable bond. Thus, they needed a method to adhere the composites effectively, efficiently, and confidently.

    Learn how a few drops of water, American ingenuity, and an Air Force SBIR contract are changing how we design and build in the future.

  • This interactive tutorial provides a comprehensive look at common industry practices, including typical surface preparation methods for composites and an overview of the basic scientific principles involved in measuring surface energy and how it relates to material performance in manufacturing and repair.

    This presentation will focus on universal methods and techniques used to measure and achieve durable and consistent surface preparation in manufacturing across all industries.

    Ensuring surface condition and consistency is a vital component for guaranteeing success in sealing, coating, bonding, painting, printing or cleaning.

    Primary Topics:

    • Common Surface Preparation Methods and Techniques for Composite Substrates.
    • What is Surface Energy and Why is it Important to Maintain and Understand it in Manufacturing.
    • How to Measure Surface Energy in a Manufacturing or Repair Environment.
    • Using Surface Energy Measurements to Modify Surface Quality, Determine Optimal Processes, and Perform Quality Assurance.
  • The interactions between a bond surface and an adhesive that determine the strength and reliability of a bonded structure occur in a zone that is perhaps 1 nanometer thick.

    This interactive tutorial provides a comprehensive look at the characteristics of a bond surface that determine bond performance, how to establish these characteristics through surface preparation, and how to quantify them for quality assurance.

    We will review common industry practices, including typical surface preparation methods for composites and an overview of the basic scientific principles involved in measuring surface composition and surface energy and how these relate to material performance in manufacturing and repair.
