About the Topics
Jeff Satterwhite
The consistency of contact angle bonding theory with experimental bonding performance is examined for an aerospace grade toughened epoxy-carbon fiber prepreg system cured at 176°C with peel ply surface preparation. Contact angle measurement, x-ray photospectroscopy and scanning electron microscopy are performed to analyze the surface; experimental bond strength testing by the rapid adhesion test is carried out afterward using aerospace grade 176°C cure adhesives. Comparison of the bonding theory generated from the contact angle measurement and the actual bonding performance will be carried out and assisted by knowledge of surface morphology and chemistry by the SEM and XPS examinations.
Brian Clark
The Rapid Adhesion Test ("RAT") was developed as a simple, fast Mode I screening process for rejecting component combinations that fail in adhesion, taking advantage of the qualitative nature of this determination. Various combinations of 127 °C (260 °F) cure glass fiber reinforced polymer prepreg, nylon and polyester peel plies, and film adhesives were tested using the RAT. In addition, the peeled surfaces were characterized using SEM and contact angle measurements.
Ryan Toivola
Current methods of non-destructive testing have difficulty identifying the 3D position of damage in a composite laminate, and are often limited in resolution. "Active" NDE methods can provide real-time measurement of stress-strain properties but add weight and complexity to manufacturing. We are attempting to adapt an existing imaging technique, 2-photon fluorescence imaging, into an active, 3-D-capable, multi-property-sensitive non-destructive test method for polymeric composites.

About the Speakers
Jeff Satterwhite
Jeff is a 21-year-old senior with the University of Washington's Materials Science and Engineering Department and will be continuing his graduate education under Professor Brian Flinn beginning in Fall 2007. His research interests include aerospace composite materials and surface adhesion.
Brian Clark
After professionally developing software for several years, Brian Clark decided to make a career change and went back to school to pursue a Master's degree in Materials Science. He hopes to stay in the Puget Sound area and find a job in industry after his degree is finished.
Ryan Toivola
Ryan Toivola received his undergraduate degree in Mathematics/Physics from Whitman College. He is currently pursuing his PhD at in the Flinn Group at the University of Washington's MSE program. His eventual career goal involves research & development in the aerospace or sporting goods industries.
