Dr. Carlos Barrios, a colleague of mine from 3M St. Paul, asked over dinner at the last meeting of the Adhesion Society if I would like to take part in teaching a week-long course in polymers at the leading university in Colombia.
The course took place at Universidad Nacional in Bogota, Colombia. About 50 engineering students and several professional engineers from the community attended.
I taught the course in conjunction with Carlos and Omar Arias (Manager of Technical Service for 3M in Latin America).
We split the course into three segments: I taught “Fundamentals of Surface Energy and Adhesion”; Carlos taught “Recent Advances in the Science of Pressure Sensitive Adhesives”; and Omar taught “3M Solutions through High Performance Pressure Sensitive Adhesives”.
My segment of the class included hands-on experiments that demonstrated the relationships between surface energy and peel strength of pressure sensitive adhesives.
The students were incredibly engaged; as a result, the class lasted for almost 11 hours. The questions were technically very advanced and indicated a wonderful level of interest.
Bogota was a wonderful experience in itself. Founded by the Spanish Conquistadores in 1538, the old part of the city looks and feels like a medieval Spanish city. …Read More
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.
