CMH-17: Composite Materials Handbook

Ongoing Advancements in the Field of Composite Materials

 BTG Labs maintains an important connection to  CMH-17, the Composite Materials Handbook. BTG Labs recently attended a regular conference which brings groups and companies together for the discussion of developing and engineering composite materials. Members also give presentations on the latest in composite developments.


BTG Labs ' special connection began in 2004 when Giles Dillingham, CEO and Chief Scientist of BTG Labs read that CMH-17 declared surface preparation as the number 1 problem in manufacturing implementation. This promoted a lack of trust in adhesive bonding. Thus, a need to monitor, measure, and maintain surface processes began to take shape.

These were some of the first murmurings that lead to the idea that a better way in which to measure and monitor surface process was needed. Today, the Surface Analyst™ provides a way to confidently measure and monitor surface sensitive processes. At BTG Labs, we continue to evolve our technology every day and the resources such as CMH-17 help move us forward.

CMH-17 is a handbook that creates, publishes, and maintains proven and reliable information and standards on composite development, utilization, and manufacturing. They provide the information and guidance necessary to design and fabricate end items from composites materials. The members meet every nine months to collaborate and share the latest innovations in the composites field. An engineer from the BTG Labs team recently returned from the latest CMH-17 meeting. The big question asked: "How can we quantify surface preparation?"


Three Main Issues Concerning Surface Preparation of Composite Materials:

  1. Lack of trust in adhesive bonding
  2. Absence of standards
  3. Weak to nonexistent monitoring processes

These issues are interconnected. The lack of trust comes from a lack of standards and way to monitor surface processes. BTG Labs has the chance to contribute a solution to these concerns. The Surface Analyst provides a way in which to measure and monitor surface processes. Consequently, it can help develop standards and procedures. Finally, with determined processes and procedures, and a way to verify these processes, the Surface Analyst provides the trust desired for a successful adhesive bond.

BTG Labs looks forward to future collaborations and developments with its relationship with CMH-17.
