(YIP) 4D PRINTING MATERIALS WITH PROGRAMMED RESPONSIVENESS AND STIFFNESS FOR MULTIFUNCTIONAL ADAPTIVE ARCHITECTURES
Abstract
4D printing is a rapidly emerging field in which 3D printed stimuli responsive materials are used to produce shape changing and multifunctional architectures, with time being the fourth dimension. Despite the surge of scientific inquiries into 4D printing of responsive polymer composites, existing investigations have been limited to designing printable inks and architectures with a focus on either the response to stimulus, or the ability to bear load, but not both. Accomplishing this would make 4D printing a viable way to manufacture new multifunctional shape-shifting architectures of relevance to the United States Air Force, such as adaptive, autonomous, and reconfigurable aerial vehicles, missiles, antennas, and deployable systems. Toward this effort, the overall goal of this research is to develop and integrate new materials, processes, and architectures to create load-bearing, multifunctional aerial structures that achieve various controlled and programmed shapes on demand. This research gives a new path forward to creating multifunctional aerial structures that can change shape on demand.
