Summary: | Bioinspired materials draw upon the structures and processes observed in living
organisms, including plants, animals, and microorganisms, to develop materials that
possess distinct characteristics. This type of material typically possesses remarkable
properties such as being lightweight, combined with exceptional strength and
toughness which allows for application across diverse fields such as engineering,
medicine, and environmental conservation. However, replicating bioinspired materials
has posed significant challenges. While several successful attempts have been made to
mimic their structural and mechanical features, these efforts typically involve
demanding considerable energy input and are often constrained by various limitations.
In this study, the objective is to replicate and fabricate one of these natural materials
known as Nacre. The goal is to create a nacre-inspired composite consisting of
ceramics and metals using magnetically assisted slip casting. By varying the initial
conditions before and during the fabrication process, this study aims to understand the
effects of these conditions on the microstructure and in the process identify the optimal
conditions and parameters to obtain a composite with desirable quality.
This processing methodology holds promise for generating lightweight synthetic
materials possessing enhanced strength and toughness. Such a material obtained by
this fabrication technique could find its way into industries such as construction,
aerospace, and marine among many others. |
