Available in PDF, EPUB and Kindle. Book excerpt: The goal of this program was to produce continuous strong CNT-based fibers. The production of continuous fibers was met and we have matched 2/3 of the strength of what has been previously reported with CNT-PAN fibers. We believe that with additional spinning process optimization we can increase the resultant fiber strength. All of the mechanical data shown (below) was generated from a non-optimized spinning process. This preliminary data generated from just the first fiber run shows promising results. The SWNT-PAN fibers obtained using our Set up have a tensile strength of 238 MPa at 300% draw ratio. The produced fibers have very uniform diameter (see SEM images) so the mechanical properties are uniform across the length of the fiber. As a comparison to our initial data Satish Kumar was able to produce SWNT-PAN fibers using 5wt% of SWNT with a tensile strength of 360 MPa at 460% draw ratio. We have started to optimize the spinning process and the other parameters to improve the overall mechanical properties of the fibers.

This book was released on 2012-09-14 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The well documented increase in the use of high performance composites as structural materials in aerospace components is continuously raising the demands in terms of dynamic performance, structural integrity, reliable life monitoring systems and adaptive actuating abilities. Current technologies address the above issues separately; material property tailoring and custom design practices aim to the enhancement of dynamic and damage tolerance characteristics, whereas life monitoring and actuation is performed with embedded sensors that may be detrimental to the structural integrity of the component. This publication explores the unique properties of carbon nanotubes (CNT) as an additive in the matrix of Fibre Reinforced Plastics (FRP), for producing structural composites with improved mechanical performance as well as sensing/actuating capabilities. The successful combination of the CNT properties and existing sensing actuating technologies leads to the realization of a multifunctional FRP structure. The current volume presents the state of the art research in this field. The contributions cover all the aspects of the novel composite systems, i.e. modeling from nano to macro scale, enhancement of structural efficiency, dispersion and manufacturing, integral health monitoring abilities, Raman monitoring, as well as the capabilities that ordered carbon nanotube arrays offer in terms of sensing and/or actuating in aerospace composites.
Download or read book Carbon Nanotube Reinforced Polyacrylonitrile and Poly etherketone Fibers written by Rahul Jain and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The graphitic nature, continuous structure, and high mechanical properties of carbon nanotubes (CNTs) make them good candidate for reinforcing polymer fiber. The different types of CNTs including single-wall carbon nanotubes (SWNTs), few-wall carbon nanotubes (FWNTs), and multi-wall carbon nanotubes (MWNTs), and carbon nanofibers (CNFs) differ in terms of their diameter and number of graphitic walls. The desire has been to increase the concentration of CNTs as much as possible to make next generation multi-functional materials. The work in this thesis is mainly focused on MWNT and CNF reinforced polyacrylonitrile (PAN) composite fibers, and SWNT, FWNT, and MWNT reinforced poly(etherketone) (PEK) composite fibers. To the best of our knowledge, this is the first study to report the spinning of 20% MWNT or 30% CNF reinforced polymer fiber spun using conventional fiber spinning. Also, this is the first study to report the PEK/CNT composite fibers.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: To further improve and upgrade the existing functions of carbon fibers, and to endow the carbon fiber with new and desired functions, the most effective and economic way is to create nanostructures on the carbon fiber surface. The carbon fibers with nanostructures grown on the surface, or namely nanostructured carbon fibers, not only maintain the intrinsic high strength, light weight, high thermal conductivity of carbon fiber, but also obtain significant functional enhancements in mechanical properties, interfacial bonding and electrocatalytic property. Different kinds of nanostructures, such as nanoparticles, nanorods, nanotubes, nanosheets, and nanoflowers, are controllably grown on the surface of carbon fibers by using various kinds of techniques, including chemical vapor deposition (CVD), laser ablation, microwave treatment, and hydrothermal process. These multi-scale, multifunctional nanostructured carbon fibers not only add new and interesting branches to the carbon fiber family, but also pave the way for the application of carbon fibers in next-generation fiber-reinforced composite, energy storage device and green energy production.

Download or read book Nanotube Superfiber Materials written by Mark J. Schulz and published by Elsevier Inc. Chapters. This book was released on 2013-09-16 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotubes are a unique class of materials because their properties depend not only on their composition but also on their geometry. The diameter, number of walls, length, chirality, van der Waals forces, and quality all affect the properties and performance of nanotubes. This dependence on geometry is what makes scaling-up nanotubes to form bulk material so challenging. Nanotubes are also unusual because they stick together to form bundles or strands. Nanotube superfiber materials are fibrous assemblages of nanotubes and strands. The hope and dream of researchers around the world is that nanotube superfiber materials will have broad applications and change engineering design. This chapter gives a perspective on nanotube superfiber development. This chapter discusses new applications—where we think we can go with the material properties and what applications will be enabled—and new techniques for developing superfiber material.
Download or read book Multifunctional Carbon Nanotube Fiber Composites written by and published by . This book was released on 2004 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The project provides a spinning process that results in continuous nanotube composite fibers that are about an order of magnitude tougher than any fibers made by mankind or nature. We make two hundred-meter long reels of continuous nanotube-polymer composite fiber at 70X the prior-art rate and achieve fiber strengths higher than 1.8 GPa. Our drawn nanotube fibers match the energy absorption capability of spider silk up to the breaking strain of this silk (30%), and continue absorbing energy until they reach an energy-to-break of 570 J/g, as compared with 160 J/g for the spider silk and 50 J/g for Spectra fiber, 33 J/g for Kevlar fiber. The density-normalized fiber tensile strength is presently 2.2X that of high performance steel wire and the density-normalized Young's modulus of the nanotube fiber and steel wire are identical. We have fabricated these fibers into 100 micron diameter, high performance supercapacitors that are woven into textiles. Other major advances in nanotube spinning, actuation, energy storage, and thermal energy harvesting are described which are potentially important for synthetic multifunctional materials applications.
