Snappy: A New Automated Testing Machine for Monitoring the Break Evolution Process during Single Fiber Fragmentation Test

October 14, 2022
Author(s)
Ami Ahure Powell, Richard Sheridan, Berkay Yucel, Sezen Yucel, Evan Rust, Jeremiah Woodcock, Jeffrey Gilman, Surya R. Kalidindi, Gale A. Holmes
A measurement of interfacial shear strength (IFSS) in fiber reinforced polymer (FRP) materials remains elusive after more than fifty years. This is due in part to the many sources of uncertainty, the time-consuming nature of the measurements, and the large
