MATERIALS INFORMATICS APPLIED TO NANOCOMPOSITES FOR ADVANCED DIELECTRIC TECHNOLOGY

Project: Research project

Project Details

Description

Northwestern will perform simulations of nanocomposite systems for thermomechanical properties and dielectric properties. Work will entail reconstruction of nancomposite morphologies, meshing in finite element software and analysis using ABAQUS and COMSOL. Correlation functions will be used to get statistical representation of composite structures, starting with known expressions for spherical fillers. Extensions will be made to allow representation of nanorod and nanoplate fillers and a descriptor distribution method will be established to reconstruct geometry without need of correlation functions. Important morphological features include filler average size and aspect ratio, distance between nearest fillers and orientation distribution of fillers. Algorithms will be established to ensure overlap of fillers in reconstruction is avoided. Work will integrate tightly with RPI colleagues to identify energy parameters to correlate to interphase properties and to dispersion/morphology parameters. Property predictions will include glass transition temperature, full storage and loss modulus curves, dielectric constant and breakdown strength. Some limited experimental work may be performed to characterize interphase properties or measure mechanical or dielectric properties. The bulk of the experimental characterization will be performed at RPI. Materials genome concepts of data mining and analysis will be performed in conjunction between RPI and NU.
