Research Overview

  • Composites for energy infrastructure - Long-term aging and progressive damage simulations of pultruded composites for next–generation power lines
  • Non-autoclave processing of composites - Control of porosity and defects in out–of-autoclave prepregs for aerospace composite laminates
  • 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
  • Acoustic metamaterials - Measurement and computer simulation of noise transmission loss and acoustic/vibration damping in 2D membrane-type metamaterials. The objective is the design of a new generation of grid or sandwich panels with improved transmission and damping characteristics for noise reduction in air and land vehicles
  • 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
