Structure-property relations in advanced composites

November 1, 2017 @ 6:30 am - 7:30 am

A major theme in the field of advanced composites is correlating the material microstructure with its performance. Fundamental understanding of this correlation is critical for tailored development of optimal microstructures for targeted performance in lightweight and high strength structural applications. Material hierarchy, inhomogeneity and anisotropy – inherent to advanced composites – make the development of accurate structure-property relations quite challenging. Additionally, effective preservation of optimal microstructures is needed during composite manufacturing, where even minor variations result in varied structure-property relations across the acreage of a structural component. Dr. Suhasini’s research group – Advanced Materials and Processing Laboratory (AMPL) at Aerospace Engineering, Indian Institute of Science (IISc), Bangalore – explores issues at the intersection of composite microstructure, composite manufacturing, and structural integrity. In this talk, Dr. Suhasini will be specifically talking about an approach towards multi-scale progressive damage development in laminated composites by explicitly accounting for constituent damage models at the micro-scale. Manufacturing defects due to processing and secondary manufacturing contribute to the final structural integrity of the structure; inclusion of these defects in the multi-scale framework will also be discussed. The bulk of the talk will be focussed on PMCs, some preliminary studies on CMCs shall also be briefly discussed.
