Abstract: Transportation industries desire lightweight materials because they can increase fuel efficiency and reduce greenhouse gas emissions. Although lightweight, fiber-reinforced polymer matrix structural composite materials can offer significant advantages to the automotive industry, manufacturing protocols are not yet competitive with conventional processing methods such as metal stamping. We have adopted a concerted interdisciplinary research approach to overcome the barriers to realizing such technology. Our research approach involves new chemistry and processing methods of high yield carbon precursors, polymer matrix-reinforcing fiber interfacial engineering, high- and low-shear rheology of materials, tailoring performance based on application need and development of multifunctional self-sensing composites. We aim to control structures in multiphase soft matter matrix, consisting of a rigid reinforcing segment and a soft flexible segment, with adequate interfacial adhesion between these two phases. This allows us to devise soft matter-based easy-to-process novel composites. This presentation will give an overview of our approach to enhance the performance and functionality of new fiber-reinforced composites. We also conduct conversion of renewables to engineered bioproducts and biocomposites with superior performance and 3D printability. These materials can have potential applications as structural and semi-structural components in an automotive, building, and other household applications. Successful industrial adoption and commercialization of our processes will also be presented.
