Increasing Performance for Aircraft and Spacecraft Applications

The research in the University of Dayton Polymer and Composites Lab revolves around the development and testing of new lightweight materials for aircraft and spacecraft applications, such as composites and adhesives. Our additional focus is on improved flame retardants for these materials, which is a collaboration between the University of Dayton Research Institute (UDRI) and the University of Dayton Department of Chemistry and Department of Civil and Environmental Engineering and Engineering Mechanics. Learn more about the Center for Flame Retardant Material Science. 

Dr. Klosterman works with students from the undergraduate to doctoral levels providing relevant hands-on experience in materials preparation, processing and testing.  The UD student chapter of SAMPE also utilizes this lab space for the annual composite bridge building contest design competition.
