Research Projects

Composites Manufacturing:
Processing and characterization of fiber reinforced composites fabricated by wet lay-up, autoclave, resin transfer molding (RTM), vacuum-assisted resin transfer molding (VARTM) and other composite manufacturing processes. Investigating effect of processing parameters on thermal and mechanical properties of manufactured parts under static and dynamic loadings. Fiber elastomeric sizing role in fiber wetting and adhesion.

Microstructural Analysis:
Morphological characterization of microstructural defects in composite materials by microscopic methods. Investigation of the effects of different process parameters on void morphology in composites, in order to better understand void formation mechanisms and develop effective void removal techniques.
