題目："Literally Big Nano: Bulk Nanostructured Materials for Aerospace and Infrastructure Applications"

内容の概要説明：
Bulk nanostructured materials pose many challenges both in terms of characterization, design, processing, and scaling. This presentation will focus on recent work developing nano-engineered advanced composites for aerospace applications. These hybrid composites employ aligned carbon nanotubes (CNTs) to enhance laminate-level multifunctional properties of existing aerospace-grade advanced composites. Intrinsic and scale-dependent characteristics of the CNTs are used to engineer laminate-level property improvements: interlaminar shear strength, toughness, and electrical conductivity results will be discussed and the underlying mechanisms elucidated. Fundamental studies on polymer-CNT interactions led to the development of a combined top-down and bottom-up fabrication methodology that addresses several of the key issues (agglomeration, viscosity, CNT wetting, scale, alignment) that have frustrated the use of CNTs in nanocomposites and nano-engineered composites. Current research to answer key outstanding "questions of the day" related to CNT contributions to composite properties are discussed, including a novel experimental platform to investigate nanoscale interactions in a well-controlled manner. New research results and directions stemming from ongoing work will be discussed.
