“…The voids between fibers will provide the microporosity necessary for sensing and microsieving. Controlled microporosity will assist in providing functional gradients 54,55 of thermal, electromagnetic, and elastodynamic impedances. The Bragg phenomenon will be exhibited for electromagnetic 56 and elastodynamic 57 waves, if the gradients are periodic along fixed directions.…”

Abstract:The methodologies of bioinspiration, biomimetics, and bioreplication are inevitably pointing to the incorporation of multifunctionality in engineered materials when designing ever more complex systems. Optimal multifunctionality is also the defining characteristic of metamaterials. As fibrous materials are commonly manufactured from a variety of source materials, mimumes--i.e., microfibrous multifunctional metamaterials--are industrially viable even today, as exemplified by mimumes of parylene C. The microfibrous morphology of mimumes will enhance surface-dominated effects in comparison to those evinced by bulk materials. Engineered BiomimicryThe laws of physics hold sway over every biological process just as surely and as completely as over every technological operation. Yet the modification of any biological feature in response to an altered environment leading to the emergence of a new multicellular species is a much lengthier affair than the development of a new product line--especially after the Industrial Revolution, and definitely in the last few decades. In the absence of a prescient selector, natural selection promotes the propagation of the genes of better-adapted mutants, a recognizably new species appearing after some large number of generations. In contrast, feeding on consumer research, technology managers function as prescient selectors to rapidly conceive, design, manufacture, and market improved products. Furthermore, even though the sprouting of a new taxon 1,2 still remains as much of an enigma as that of an entirely novel technoscientific product, the duration of the former is remarkably shorter than of the latter.Evolution in nature may be much slower than technological evolution, but the former enjoys the advantages of plenitude of mutation. No body of prescient selectors can afford to conduct a large number of experiments in the pursuit of a new or improved product. But numerous mutations arise in nature, albeit over long periods of time. Imparting either insignificant or no reproductive advantage, most mutations do not survive for long. Although proportionally few, the reproductively successful mutations may be regarded as the successful outcomes of a gigantic multidimensional matrix of experiments. Accordingly, sapient hominins have long been inspired by attractive outcomes and functionalities evident in plants and animals.Invisibility from predators provided to animals by skin coloration matched to their environment 3 must have led hominins in the hoary past to camouflage themselves in animal skins while either hunting animals or being hunted by rivals. Today's camouflage uniforms worn by both hunters and soldiers are biomimetic descendants of animal skins. 4 Self-medication by animals to either prevent or treat certain diseases 5,6 must have led medical specialists amongst early humans towards medicinal drugs readily available from natural resources.7 Bioprospecting continues even more systematically than in the past, 8 the isolation of medicinally effective compounds from the...

“…Microfibrosity will also enhance surface-dominated phenomenons in relation to volume-dominated phenomenons, because the available surface area per unit volume will be higher than in bulk materials. 50 Spatially graded blending of different raw materials during fabrication 55 would also promote multifunctionality.…”

“…In order to successfully fabricate the FGM specimens, scholars and researchers have applied the best methods or combination of several methods depending on the characteristics of the constituent materials [3,4] by arranging one layer atop another with more than one starting material selectively until layered structure is produced. The benefits of this method are that it is able to produce unlimited number of gradients.…”

“…Numerous studies have described metalceramic FGM that combine the high temperature resistance of ceramics with the toughness of metals. 1,2) These materials exhibit different interesting properties at different regions and can be used in areas of research and development that require advanced structures, such as advanced engines, turbine blades, and thermal barrier coatings. Due to various useful properties and important applications, FGM have been studied over last few years.…”

Effect of Sintering Profile and Composition of Ni/Al<sub>2</sub>O<sub>3</sub> Functional Gradient Materials Coating Layers via Pulsed DC Electrophoretic Deposition

functional gradient material (FGM) coating layers with its thickness of 2025 µm were fabricated by pulsed direct current (DC) electrophoretic deposition (EPD). The coarsening effect of Ni was studied to control sintering profile with an intermediate step of 1000°C for 3 h. Controlling the sintering conditions through an intermediate step and varying the number of layers played important roles in reducing cracks on the coating surface. The samples were characterized using X-ray diffraction (XRD), back scattered electron microscopy (BSE) and electron probe micro analyzer (EPMA). From these analyses, the effects of sintering step on microstructures of FGM coating layers were studied systematically to minimize crack problems within Ni-rich region by controlling its composition and form gradient through coarsening of Ni particles caused by intermediate step during sintering process. The high hardness was found for two-and three-layered samples by introducing intermediate step during sintering. Hence, pulsed DC EPD method was successfully employed to fabricate crack-free FGM with desirable microstructures.
