This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon fiber (CF) composites are implemented into more and more engineering applications due to their superior strength to weight ratio over traditional materials. However, inhomogeneous microstructures of composite laminates may bring some challenges when implemented into applications. For example, due to the manufacturing methods typically used to manufacture the composite parts, there may be a resin-rich layer between the carbon fiber layers which will ultimately end up reducing the overall mechanical properties of the composite. Use of carbon nanotubes (CNTs) are a promising step forward in composite materials as evidence shows an improved strength to weight ratio over that of carbon fiber with the addition of having multifunctional capabilities. Furthermore, CNTs are at the nano or sub-microscale, and are potentially able to reduce resin-rich issues that are present in traditional composites. In this research, we focus on the scale-up study of selected CNT and CNT/CF hybrid composite concepts using continuous CNT materials, aerospace certified resin matrices, and aerospace quality manufacturing processes. The goal of this research is to gain a fundamental understanding of new CNT/CF hybrid microstructures and microstructure-property relationships of these new composites.We manufactured highly aligned CNT sheet composites via stretching process, the results show the high mechanical properties which are comparable to unidirectional carbon fiber laminates. The high degree of alignment, self-assembling, and dense packing achieved within the CNT networks are major factors which contribute to the performance of the composite. We also successfully manufactured unidirectional yarn composites via filament winding and stretching processes. The results show an attractive method of scalability to manufacture high strength CNT panels. To study the effect of CNTs on the GIC of laminates, we manufactured aerospace-quality and ASTM standard double cantilever beam test samples with different CNT layer configurations, the preliminary results show the weak interfacial bonding present within the CNT networks resulting in the low GIC property. Finally, we manufactured CNT yarn/CF hybrid unidirectional laminates to the study the effect on the microstructure and mechanical properties with the addition of aligned CNT layers. The goal is to increase overall reinforcement volume fraction and simultaneously reduce resin rich areas. Each of these results advance the fundamental understanding of the effect of CNT sheets, socks and yarns on manufacturing processes, microstructure, mechanical properties, and failure modes on traditional carbon fiber laminates for potential scaled-up structural applications.

Download or read book Carbon Nanotube Enhanced Aerospace Composite Materials written by A. Paipetis and published by Springer Science & Business Media. 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 High Performance Composite Materials Characterization of Carbon Fiber Reinforced Epoxy Matrix Composites with Carbon Nanotubes as Reinforcement Agent Within the Matrix written by Ricardo Andrés Ochoa de la Rosa and published by . This book was released on 2011 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is about mechanical characterization of high performance, structural composite materials. Within the context of this project, a commercial, now available epoxy resin reinforced with carbon nanotubes (CNT’s) was compared with a high performance commercially available epoxy resin, also using unidirectional carbon fiber as reinforcement agent. CNT’s are a relatively new, interesting topic to study within the materials science, and because of the potential shown in previous studies, are of utter importance for critical structural applications, such as those found in the aerospace industry. During this project previous references were studied and used as comparison material to design the methodological framework followed in this work. To observe CNT’s benefits, samples tailored to American Society for Testing and Materials (ASTM) standards were manufactured and tested in order to quantify the mechanical properties discussed in this. ASTM standards provide both the sample dimension requirements and the testing procedure to be followed in order to obtain reliable, organized, meaningful data from proposed tests. Tensile, shear and flexural strain-strength tests were performed in samples using both kinds of resins. Data collected from tests was organized, plotted and analyzed to understand mechanical behavior of the samples during the tests. Main engineering values such as ultimate tensile strength, engineering stress, young’s modulus, shear strength and so were gathered and documented in this project. CNT’s reinforced epoxy samples outperformed the common epoxy samples in general, showing a better behavior as seen in the deformation energy absorbed in the samples in each test. It is encouraged to keep the research on the CNT’s topic as a promising and relevant technology called to grow in use and performance in the future, as well as to expand and improve the difficulties and limitations found in this project. This project shows that even when using a low CNT’s content as reinforcement agent within the matrix, evaluated mechanical properties are effectively enhanced, making the CNT’s a good candidate for future composite material components where weight saving and better structural mechanical performance is needed.

Download or read book Characterization of Mechanical Properties in Nanoparticle Reinforced Hybrid Carbon Fiber Composites Using Photoluminescence Piezospectroscopy written by Sanjida Akter Jahan and published by . This book was released on 2017 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon fiber composites have become popular in aerospace structures and applications due to their light weight, high strength, and high performance. Hybrid carbon fiber reinforced polymer (HCFRP) composites with alumina nanoparticles reinforcement display improved material properties such as fracture toughness, resistance to crack propagation and improved fatigue life. However, homogeneous dispersion of nanoscale materials in the matrix is important for even distribution of the improved properties. Implementing silane coupling agents (SCAs) improves dispersion by acting as a bridge between organic and inorganic materials, which increases interfacial strength and decreases sedimentation by bonding the particulate filler to the fiber reinforcement. This research is aimed at quantifying the improvement in dispersion of nanoparticles and elucidating the effects on the mechanical property of HCFRP samples through the novel use of photoluminescent characteristic peaks emitted by the alumina reinforcement particles. Photo-luminescene emission from secondary reinforcement particles of alumina embedded within the hybrid carbon fiber composites is leveraged to reveal microstructural effects of functionalization and particle weight fraction as it relates to overall composite mechanics.
