A MULTISCALE MULTIPHYSICS COMPUTATIONAL MODELING AND EXPERIMENTAL STUDY FOR THERMO-OXIDATION IN POLYMERS,
Abstract
The use of polymer based materials such as polymer matrix composites (PMC) as lightweight materials are ubiquitous in the air force applications. The degradation of polymer matrices under extreme environment due to chemical aging is a constant challenge for these materials in terms of their long-term use. Thermo-oxidative aging in polymers is a temperature dependent aging process occurred due to a set of chemical reactions driven by the diffusion of oxygen. While the chemical reactions occur in a relatively smaller length scale (as in single chain or monomer level), it alters the mechanical properties of the polymer significantly at the macroscale. The objective of the proposed research is to develop an experimentally coupled theory and computational model to generate new insight in this oxidative aging process, by unraveling the coupling between the reaction kinetics and the deformation mechanics.
