| Abstract Scope |
Nature has offered much inspiration for designing bio-inspired, efficient composites. The extraction of hidden cues in hierarchical organizations, principles, and underlying structure-function relations are some of the critical approaches in bioinspired materials design. While significant effort has focused on rigid natural composites such as bone, wood, and bamboo for designing structures optimized for strength, toughness, and density, the cell walls of fast-growing plants have been under-explored. Identifying the underlying mechanics of their design can help numerous applications, ranging from flexible skin in robotics to flexible anodes for efficient battery design. In this study, we investigate the vascular tissue of a fast-growing plant sunflower to gain insights into changes in their cell wall and identify features relevant to fiber-reinforced composite design. Specifically, we focus on features responsible for growth while maintaining adhesion between fibers and layers for structural integrity during development.
To conduct the study, we perform nanoindentation on cell walls to map their elastoplastic properties. We discuss the results in the context of a comprehensive understanding of the composition and micromechanics of cell-wall structure and its implications on functional composite design. Overall, this research sheds light on the importance of examining the mechanical properties of cell walls for developing bioinspired materials with multifunctionalities and optimized interfaces. |
