Research overview

Composite Structures Advanced fiber composites have gained wide applications in aircraft and aerospace structures due to their high strength-to-weight ratio. For instance, composites on Boeing 787 dreamliner will account for 50% of aircraft's structural weight which will become the first flight to launch with composite wings and fuselage. Composite would yield better fatigue and corrosion resistance with 20% greater fuel economy. My research area concentrates on the manufacturing of fiber composite structures to improve the structural integrity, reliability, cost effectiveness as well as their structural properties.  Research topics also include developing methods for testing, understanding composite failure mechanisms, developing methods for NDE of the composite structures in service.

Nanomaterials & Nanocomposites Nanomaterials possess highly desired physical and mechanical properties mainly due their size at which they follow the quantum theory as oppose to classical physics which govern the bulk materials. Due to their extraordinary behavior, the nanomaterials find a broad spectrum of applications including but not limited to materials science and structural composites. However, from structural point of view, fabrication and processing of nano-reinforced composites are extremely challenging which still have not found a developed and reliable route. What makes this route so unpredictable and unreliable is the dispersion of nanoparticles, the quality of which determines the ultimate properties of composites - the better the greater. Moreover, people have been able to produce nanocomposites successfully only with a small percentage (3-5 wt%). My research focuses on the improvement of the dispersion quality as well as to increase the particle content (15-20 wt%) to maximize their effect. I aim to develop nanocomposite processing method to take to the level of real field application which requires reliability, consistency, mass production and last but not the least, inexpensive. My research area also covers to incorporate multi-functional properties into the nanocomposites with EMI shielding.

Micromechanical Modeling Mechanics-based composite models have proved successful in predicting the enhanced mechanical properties of particle reinforced composites. Nanocomposites differ from conventional composites because of their vast interfacial areas per unit volume. The presence of many chains at interfaces makes the polymer ‘interphase-like’ instead of having bulk-like properties. These interphase layers may potentially modify the effective mechanical properties of the polymer. Some modification must be made to model nanocomposites. To facilitate the development of quality and consistent nanocomposites materials, my research explore to answer the followings - what is good dispersion or how bad is the bad dispersion.
