Abstract: To study the effects of aluminum coupon thickness, bond line thickness, surface preparation, and presence of an overflow fillet for a high strength epoxy and ductile methacylate adhesive a parametric was used with a high quantity of sample sets. GEMS (Gains in the Education of Mathematics and Science) high school and middle school students prepared 960 single-lap-joint samples with ARL technicians fabricating and additional 240 controls. The time constraints imposed by working within the GEMS framework required a highly efficient experimental work-flow protocol to maintain high throughput and quality during fabrication. Of equal importance was maintaining data integrity during this study. This work focuses on coordinating laboratory experimental support with the U.S. Army Research Laboratory's Materials Selection and Analysis Tool (MSAT) database platform to insure [sic] both high throughput and data integrity by capturing the entire experimental response curve, supportive pedigree information, as well as experimental descriptors, which will augment further data analysis. The MSAT protocols also proved to be very pragmatic for physically tracking sample identification numbers and matching with subsequent failure surface images after mechanical testing was completed. The data is intended for eventual public release to augment the numerous academic models used to predict single-lap-joint response. The details of the data management workflow schema will be reported.
