Engineering Advanced Material Properties For Polymeric Materials Through Miscible And Immiscible Additives, Chinmay M. Saraf

Doctoral Dissertations

This dissertation focuses on engineering polymeric formulations using strategically selected additives or novel processes to achieve advanced material properties. The first chapter reviews the state-of-the-art impact modification and discusses micro-mechanics associated with soft particle toughening of polymeric materials. We present an analytical solution to elucidate the effect of concentration of rubbery domains on matrix yielding and energy absorption. Soft particle toughening relies on particle size, interparticle spacing, and concentration of rubbery phase. The second chapter demonstrates developing impact modified stereolithography (SLA) resins for the superior energy absorption of the SLA printed thermosets. SLA resins are engineered using additives that remain …
