Lightweight Multifunctional Advanced Materials
Abstract
In this project, we will develop a fundamental knowledge base to aid in understanding the processing-structure-property relationships of lightweight, multifunctional advanced materials that are scalable. While, in theory, such multifunctional composites possess tremendous potential for many advanced engineering applications, in reality, several critical ÒquestionsÓ prevent their widespread use and adaption into viable products. The key questions that need to be addressed include: (a) How to overcome the difficulty in dispersing the nano constituents into the matrix and prevent the filtering effect?; (b) What is the best way to increase the amounts of the nano elements in the composite?; (c) How to align nano particles/fibers in the matrix?; and (d) What are the key factors that govern interfacial adhesion and how can this adhesion be improved? We will attempt to address these questions through an integrated study using an innovative ÒscalableÓ synthesis technique and experimental characterizations. We argue that our proposed manufacturing method will overcome the above mentioned limitations and will deliver a revolutionary "scalable" multifunctional-multiscale polymer composite (MMC) system with enhanced electrical, mechanical and thermal properties. The novelty of our proposed MMC lies on the scalability in processing. We propose a synergistic approach involving novel multiscale fabrication, to process a new type of carbon nanofiber-graphene polymer based multifunctional composite material that will have the capability for scale-up production. Controlling the functional properties while processing a scale-up functional composite material will be the key technical challenge that we plan to address in this proposal. The proposed research will greatly assist the Air Force in accomplishing its strategic research educational and manpower development goals. In particular, this research will: -Contribute to the advancement of low density multifunctional polymeric materials science and technology. Potential applications include multifunctional coatings, optical displays, and new generation ultralight durable composites. -Develop the research capacity and infrastructure of ASU in an area of strategic value and importance to the Air Force. Significantly leverage ASUÕs facilities to produce innovative, multifunctional and multiscale materials. -Greatly assist ASU in launching a graduate program in Materials and Biomedical Engineering in 2 years. This proposal will provide thesis project topics. The proposed research will also assist in building a pipeline of scientists and engineers prepared to immediately contribute to helping the Air Force fulfill its mission.
