Symposium PM01—Architected Materials—Synthesis, Characterization, Modeling and Optimal Design
Architected materials are multi-phase and/or cellular materials in which the topological distribution of the phases is carefully controlled and optimized. Nearly two decades of research has resulted in the identification of a number of topologically simple, easy to fabricate, well established topologies (including honeycombs and truss lattices), which have been optimized for specific stiffness and strength, impact and blast protection, sound absorption, wave dispersion, active cooling and combinations thereof.
Over the past few years, dramatic advances in processing techniques, including polymer-based templating (e.g., stereolithography, photopolymer waveguide prototyping, two-photon polymerization) and direct single- or multi-material formation (e.g., direct laser sintering, deformed metal lattices, 3D weaving and knitting), have enabled fabrication of new architected materials with arbitrarily complex architectures and remarkably precise control over the geometric arrangement of solid phases and voids from the nanometer to the centimeter scale.
The ordered, topologically complex nature of these materials and the degree of precision with which their features can now be defined suggests the development of new multi-physics multi-scale modeling tools that can enable optimal design. The result is efficient multi-scale cellular materials with unprecedented ranges of density, stiffness, strength, energy absorption, porosity/permeability, chemical reactivity, wave/matter interaction and other multifunctional properties, which promise dramatic advances across important technology areas such as lightweight structures, functional coatings, bio-scaffolds, catalyst supports, photonic/phononic systems and other applications. This symposium will cover new processing methods, advanced multi-scale characterization techniques, modeling and analysis tools, and explore new automotive, aerospace, medical and energy applications.
