(YIP 10) - Bio-Inspired Interfaces for Hybrid Structures
Abstract
The structural organization of most biological materials differs fundamentally from man-made materials in being inherently heterogeneous. This structural heterogeneity arises from significant variation in composition and topological arrangement of their constituent components -- often at many different length scales, leading to intricate hierarchical organizations. In this project, the behavior of biologically-inspired synthetic surfaces and interfaces were investigated to facilitate the development of robust engineered surfaces, multi-material interfaces and joint configurations for multi-functional hybrid structures. In addition, the mechanical properties of a new class of hierarchical honeycombs with self-similar architecture were investigated. It was shown that a wide range of specific stiffness and strength can be achieved by increasing the order of hierarchy. Our study provides guidance for designing: 1) surfaces with controllable frictional and adhesion properties, 2) novel interface geometries and joint configurations for hybrid structures, and 3) low-density materials with hierarchical structural organization and tailorable properties.
