MULTISCALE MODELING OF RADIATION RESPONSE OF FIBER BASED COMPOSITES
Abstract
This project focusses on the behavior of heterogeneous materials in harsh environments, particularly the effects on two-phase microstructure (reinforcement- matrix) of a space radiation environment that may include gamma radiation, proton irradiation, neutrons irradiation as well as charged particle irradiation. Through atomistic (molecular dynamics, DFT calculations) methods and mesoscale (kinetic Monte Carlo, phase field) methods, and micro-mechanical methods we aim to develop a mechanistic understanding of how harsh environments may affect the microstructure and hence the properties of the composite. This project will build on recent and prior work of the PI on simulating radiation damage and interfacial evolution and defect evolution in materials. This project will have a strong impact on and relevance to the AFOSR mission. It will develop and provide a fundamental basis for improving composite design beyond current candidates, study combined effects - oxidizing/radiative, ablative/radiative environments, and complement experimental work on radiation effects on fiber composites.
