Composites CMRG

Composites CMRG

Consortium Lead: Prof. John Gillespie, Jr. (Univ. of Delaware)

CCDC ARL Lead: Dr. Daniel O’Brien

Model Material: S-2 Glass/Epoxy Interface

Composite materials subjected to dynamic loads are essential examples of high performance systems in the conventional sense. In order to focus on the complexities raised by the interfaces and architectures, S-2 Glass/Epoxy is the model system for the Composites CMRG. The Composites CMRG develops the fundamental understanding of the role of interfaces, component interactions, and composite architecture over the full range of length scales and time scales that are manifested in the system during the dynamic event.

Application: S-2 Glass/Epoxy provides a strong, structural backing system to support protective plates for military vehicles.
