Modeling the Microdroplet Test Method

Authors: Subramani Sockalingam, John W. Gillespie, Jr., and Michael Keefe

MICRODROPLET EXPERIMENTAL METHOD

• Fiber matrix interface – potential source of energy absorbing mechanism
• Residual stresses due to CTE mismatch result in radial compression leading to enhanced energy absorption
