Polymer Nanocomposite Material Design
Goals.
(1) Increase transportation materials performance,
(2) ballistic protection, and
(3) fracture toughness
Atomic bonds visible Aggregated structure,
interface morphology
clear
Random atomic
phase-space
Random secondary
microstructure,
interface morphology
Filler network visible,
detailed shape
information lost
Random aggregation,
mesostructure
Design materials: multiple monomers, fillers, interphase, interface
Filler shape invisible,
statistical homogeneity
Random primary
substructure, statistic
homogeneity
Increasing resolution, decreasing spatial scale, increasing uncertainty
Experiments at various spatial and temporal scales and its statistical analysis are important
Homogeneous medium
Random operating
conditions
Co-polymer design, interface and interphase design, experimental imaging at various scales (V2, V1)
The above is for matrix materials, now we need to add in structural materials to become polymer
matrix composites
