DESCRIPTION:Prof. Namiko Yamamoto\, Department of Aerospace Engineering\, 
 Penn State University\nLink for remote attendance: https://epfl.zoom.us/j
 /586806476\n\nThe goal of our laboratory is to enable bulk application of 
 novel multi-scale engineered materials (polymer nanocomposites\, ceramics\
 , and metals) in next-generation structures\, devices\, and systems in ext
 reme environments including aerospace applications.  In this talk\, three
  on-going research projects will be presented.  First project is about co
 ntrolled integration of nano-reinforcements to reinforce fiber-reinforced 
 plastics. Nanofillers are organized in a tunable manner by taking advantag
 e of oscillating magnetic fields\, or magnetic attraction and repulsion. T
 he critical effect of nanofiller contacts/interfaces on transport properti
 es and scalable manufacturing such nano-reinforced composites will be disc
 ussed. Second project is about hierarchical structuring of ceramic composi
 tes to achieve toughening with "soft" boundary phases. Among many aerospa
 ce ceramics\, boron carbide is of interest because it is light-weight\, th
 ermally stable\, hard/stiff\, and multi-functional (semiconducting\, therm
 oelectric\, and high neutron absorption cross-section)\, but brittle and i
 s difficult to sinter.  A hierarchical structure was designed to have of 
 micro-grains with soft interfaces for toughening without weakening\, and w
 as achieved with field assisted sintering technology with its rapid heatin
 g rate and thus improved diffusion. Third project is about functional grad
 ing of Ni-based superalloy turbine blades. Again\, field assisted sinterin
 g was used to powder-sinter and bond superalloy of dissimilar crystalline 
 for improved performance. Bulk application of these new materials is curr
 ently limited due to incomplete processing-structure-property relationship
  studies\, and lack of scalable manufacturing technology.  We work to fil
 l in these gaps\, evaluate how nano-scale behaviors are translated to macr
 o-scale properties\, and establish the design space and certification proc
 ess to achieve application of these novel materials.
