(YIP) HARNESSING THE MECHANICS OF BASKET WEAVING TO CREATE 3D HIERARCHICAL STRUCTURES
Abstract
While planar woven textiles are commonly used in engineering, principles of basket weaving which can create more sophisticated geometries and structures have remained unexplored. Thus, our objective is to investigate the underlying geometric mechanics of complex 3D woven assemblies and harness these advanced designs to enable multi-scale fabrication of systems with improved structural performance, hierarchical properties, and tunable behaviors. We will first create analytical models that can rapidly simulate the mechanics and interactions of different ‘weaver’ types (i.e. sheets or fibers). The models will be able to capture stiffness, deformations, contact, friction, and self-stress in the 3D woven systems. The models will be calibrated, validated, and verified using high-fidelity simulations and testing of physical woven prototypes. Next, we will use parametric studies to investigate how the weaver mechanics, weaving patterns, weaver interactions, and weaving process affect the final shape. For different weave design parameters, we will quantify the shape complexity that can be woven considering physical and practical limitations of the mechanics and the weaving process. We will explore how the doubly curved woven surfaces enhance stiffness (similar to a dome), and will evaluate the system resilience to localized failures. Finally, we will create and investigate woven systems that offer shape and surface morphing characteristics. The proposed basket weaving concepts can provide numerous benefits to aerospace applications. First, 3D weaving offers a new versatile method for rapid multi-scale fabrication from compactly spooled materials. The woven networks then offer high stiffness-to-weigh ratios and improved resilience to localized damage (e.g. from debris impact in hypersonic flight). Furthermore, the woven systems allow for compliance and reconfiguration which could enable morphing wings or aircraft bodies with adaptable surface roughness to tune aerodynamic characteristics. Finally, embedding composite materials within the woven system can allow for advanced capabilities in sensing, communication, and multi-physical behaviors (e.g. cloaking).
