Metal-matrix composites (MMCs) are engineered combinations of two or more materials. Tailored properties are achieved by systematic combinations of different constituents. Specialized design and synthesis procedures allow unique sets of material properties in composites. Covetics are a new type of metal-matrix nano-composite (MMnC) material. These materials are formed from FCC metals which are super-saturated with up to ~10 wt. % of activated nano-carbon powder. The idea is that the nano-carbon particles will enhance the material properties of the base metal matrix, however most of the physical and mechanical properties of covetics have not been well characterized. The foci of this study are to optimize the covetic casting synthesis process under controlled conditions, to understand and analyze the microstructures of the synthesized copper and aluminum covetic, to provide a thorough analysis of the chemical composition of the synthesized covetic materials, and to characterize physical and mechanical properties of both of these materials using meticulously prepared samples and test procedures.

This collection brings together engineers, scientists, scholars, and entrepreneurs to present their novel and innovative contributions in the domain specific to metal-matrix composites and on aspects specific to processing, characterization, mechanical behavior, measurements, failure behavior, and kinetics governing microstructural influences on failure by fracture. Topics include but are not limited to: • Metals and metal-matrix composites • Nano-metal based composites • Intermetallic-based composites Contributions in the above topics connect to applications in industry-relevant areas: automotive; nuclear and clean energy; aerospace; failure analysis; biomedical and healthcare; and heavy equipment, machinery, and goods.

This volume presents the characterization methods involved with carbon nanotubes and carbon nanotube-based composites, with a more detailed look at computational mechanics approaches, namely the finite element method. Special emphasis is placed on studies that consider the extent to which imperfections in the structure of the nanomaterials affect their mechanical properties. These defects may include random distribution of fibers in the composite structure, as well as atom vacancies, perturbation and doping in the structure of individual carbon nanotubes.

From the Foreword, written by legendary nano pioneer M. Meyyappan, Chief Scientist for Exploration Technology NASA Ames Research Center, Moffett Field, California, USA: "...there is critical need for a book to summarize the status of the field but more importantly to lay out the principles behind the technology. This is what Professor Arvind Agarwal and his co-workers ... have done here." Carbon Nanotubes: Reinforced Metal Matrix Composites reflects the authors’ desire to share the benefits of nanotechnology with the masses by developing metal matrix carbon nanotube (MM-CNT) composites for large-scale applications. Multiwall carbon nanotubes can now be produced on a large scale and at a significantly reduced cost. The book explores potential applications and applies the author’s own research to highlight critical developmental issues for different MM-CNT composites—and then outline novel solutions. With this problem-solving approach, the book explores: Advantages, limitations, and the evolution of processing techniques used for MM-CNT composites Characterization techniques unique to the study of MM-CNT composites—and the limitations of these methods Existing research on different MM-CNT composites, presented in useful tables that include composition, processing method, quality of CNT dispersion, and properties The micro-mechanical strengthening that results from adding CNT The applicability of micro-mechanics models in MM-CNT composites Significance of chemical stability for carbon nanotubes in the metal matrix as a function of processing, and its impact on CNT/metal interface and mechanical properties Computational studies that have not been sufficiently covered although they are essential to research and development The critical issue of CNT dispersion in the metal matrix, as well as a unique way to quantify CNT distribution and subsequently improve control of the processing parameters for obtaining improved properties Carbon Nanotubes: Reinforced Metal Matrix Composites paints a vivid picture of scientific and application achievements in this field. Exploring the mechanisms through which CNTs are enhancing the properties of different metal-based composites, the authors provide a roadmap to help researchers develop MM-CNT composites and choose potential materials for use in emerging areas of technology.

This book covers topics related to structural composite materials such as processing, characterization, applications and challenges. The book presents ways of processing composites, where different types of composites can be processed depending on the type of reinforcement and matrix. It also outlines the evaluation of mechanical properties of a few processed composites and discusses the potential applications of composites and machining challenges faced in processing polymer and ceramic composites. The book caters to material scientists, industrial practitioners, researchers and students working on structural composite materials.

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.
