Manufacturing of lightweight hybrid composites by bridging nanotechnology and industrial manufacturing

  • Set up a sheet molding compound (SMC) manufacturing line from scratch.
  • Introduced two novel scalable techniques to incorporate cellulose chart
    nanomaterials (CNC) in glass fiber/epoxy composites in an SMC line
    (mixed in the resin and as coating on fibers) to produce lighter composites for better fuel efficiency and lower CO2 emission in auto/marine composite components.




  • Cellulose nanomaterials (CNC, CNF) and graphite nanoplatelets synthesis and their nanocomposites characterization and utilization.
  • process-structure-property: Investigated the effect of manufacturing method, e.g. melt compounding/injection molding, selective laser sintering on nanocomposites properties.
  • Explored interfacial interactions (micro/nano scale) and synergy of CNC, i.e. 1) as a coating on fiber surface and 2) as dispersion in polymer matrix, with other components and its effect on macroscopic properties of polymer composites.


Manufacturing of novel composites in industrial scale

  • Introduced new technology to use uncured prepreg trim waste (remained from aerospace industries) in SMC manufacturing to produce high value carbon fiber/epoxy composites targeted for new markets.
  • Introduced new technology to use ecofriendly basalt fibers in SMC manufacturing to produce lighter composites in comparison with glass fiber composites.
  • Working on improving the mechanical performance of carbon fiber/epoxy adhesive joints of wind turbines using a two-step VARTM manufacturing process.


  • Working on microstructure property linkage to understand the effect of geometry and interfacial interactions of composite components on macroscopic behavior.

Mathematical modeling, simulation and experimental study of damage in multidirectional polymer composites and its influence on creep

  • Developed a model based on 3-D variational analysis combined with a viscoelastic energy-based failure criterion integrated in a lamination theory framework to predict process-induced, quasi-static and time-dependent damage evolution and their effect on mechanical properties and creep behavior of multidirectional carbon fiber-reinforced polymer (CFRP) composite laminates.
  • Developed a model based on continuum damage mechanics (CDM) to predict the influence of time-dependent damage on creep of multidirectional CFRP composite laminates.
  • Experimental characterization of various damage modes in multidirectional carbon fiber/epoxy composite laminates developed under various loading and temperature conditions using microscopy and X-ray tomography.
