Grad student honored for liquid body armor research

Ronald Egres, a doctoral candidate in the Department of Chemical Engineering
3:24 p.m., Dec. 8, 2004--Graduate student Ronald Egres, a doctoral candidate in the Department of Chemical Engineering, has won a scholarship from the Industrial Fabrics Foundation for research that focuses on the energy dissipating properties of fabrics impregnated with shear-thickening fluids.

The research focuses on a liquid that hardens on impact and has the potential to improve the protective ability and comfort of body armor worn by soldiers and law enforcement officers.

The scholarship is for one year and is applied toward tuition and research expenses.

The research is a collaborative effort among UD’s Department of Chemical Engineering, UD’s Center for Composite Materials and the Army Research Laboratory at the Aberdeen Proving Ground in Maryland. This team is developing fabrics and materials incorporating fluids that undergo a dramatic reversible transition from liquid to solid upon ballistic or stab-type impact.

Norman Wagner, professor of chemical engineering, is the leader of the UD research team.

"The guidance of Prof. Norman Wagner at UD and Dr. Eric Wetzel of the Army Research Laboratory in Aberdeen, Md.--the conceptual inventors of this technology, have lead this research team to make contributions beyond the concept stage--facilitating and participating in our effort to develop prototype materials and constructions that may one day be incorporated into protective garments for police officers and soldiers in the field," Egres said.

He said it’s been a “fantastic opportunity” observing the research effort’s transition from vision to proof of concept to optimization.

“It is a great feeling to be part of a development effort focused on better protecting those people who have dedicated their lives to protecting us and our way of life,” he said.
