  • Interfacial phenomena
  • Acoustics and vibrations of sandwich structures 

Research Overview

  • Composites for energy infrastructure - Design, analysis, and mechanical behavior of pultruded composites for high-temperature low-sag conductors
  • Non-autoclave processing of composites - Resin impregnation and low pressure processing of non-autoclave prepregs for aerospace applications.
  • High-temperature response of composites - Behavior of composites under rapid transient heating, including failure mechanisms and computational modeling intended to translate to design tools for hypersonic airframe components.
  • Sandwich panel acoustics - Measurement and computer simulation of noise transmission loss and acoustic/vibration damping in honeycomb sandwich panels. The objective is the design of a new generation of aircraft floor panels with improved transmission and damping characteristics for noise reduction in passenger cabins.
  • Polymer nanocomposites - Synthesis of nanoclay and nanotube reinforced polymers with improved mechanical properties. Applications include improved damping characteristics and shape memory characteristics through improved understanding of processing-structure relations.
  • Metallic foams - Synthesis and properties of aluminum and steel foams for sandwich core applications and energy absorption.
