Tough, bio-inspired hybrid materials.
The notion of mimicking natural structures in the synthesis of new structural materials has generated enormous interest but has yielded few practical advances. Natural composites achieve strength and toughness through complex hierarchical designs that are extremely difficult to replicate synthetically. We emulate nature's toughening mechanisms by combining two ordinary compounds, aluminum oxide...
متن کاملBio-inspired Design and Fabrication of Super-Strong and Multifunctional Carbon Nanotube Composites
Carbon nanotubes (CNTs) are ideal scaffolds to design and architect high-perform‐ ance composites at high CNT volume fractions. In these composites, the CNT align‐ ment determines the level of aggregation and the structure morphology, and thus the load transfer efficiency between neighboring CNTs. Here, we discuss two major solutions to produce high-volume fraction CNT composites, namely the la...
متن کاملCarbon nanotube reinforced ceramic composites and their performance.
Carbon nanotubes are considered as excellent reinforcements for improving the properties of ceramic composites. This paper reviews the reported techniques for the preparation of various ceramic coated CNTs, CNT-ceramic composites, CNT-ceramic composite coatings, etc. It is noted that a wide range of techniques have been used to fabricate these composites. Their characterisation has revealed tha...
متن کاملMultifunctional Composites of Ceramics and Single-Walled Carbon Nanotubes
Polycrystalline ceramic/single-walled carbon nanotube (SWNT) composites possess unique grain boundaries, containing 1D tortuous SWNTs bundles that form 2D tangled embedded nets. This unprecedented grain-boundary structure allows tailoring of multifunctional ceramic/SWNTs composites with unique combinations of desirable mechanical (toughness, strength, creep) and transport (electrical, thermal) ...
متن کاملOptimizing the design of bio-inspired functionally graded material (FGM) layer in all-ceramic dental restorations.
Due to elastic modulus mismatch between the different layers in all-ceramic dental restorations, high tensile stress concentrates at the interface between the ceramic core and cement. In natural tooth structure, stress concentration is reduced by the functionally graded structure of dentin-enamel junction (DEJ) which interconnects enamel and dentin. Inspired by DEJ, the aim of this study was to...
