Book High Performance Structural Fibers for Advanced Polymer Matrix Composites

Download or read book High Performance Structural Fibers for Advanced Polymer Matrix Composites written by National Research Council and published by National Academies Press. This book was released on 2005-05-09 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military use of advanced polymer matrix composites (PMC)â€"consisting of a resin matrix reinforced by high-performance carbon or organic fibersâ€"while extensive, accounts for less that 10 percent of the domestic market. Nevertheless, advanced composites are expected to play an even greater role in future military systems, and DOD will continue to require access to reliable sources of affordable, high-performance fibers including commercial materials and manufacturing processes. As a result of these forecasts, DOD requested the NRC to assess the challenges and opportunities associated with advanced PMCs with emphasis on high-performance fibers. This report provides an assessment of fiber technology and industries, a discussion of R&D opportunities for DOD, and recommendations about accelerating technology transition, reducing costs, and improving understanding of design methodology and promising technologies.

Book Engineered Interfaces in Fiber Reinforced Composites

Download or read book Engineered Interfaces in Fiber Reinforced Composites written by Jang-Kyo Kim and published by Elsevier. This book was released on 1998-10-21 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study and application of composite materials are a truly interdisciplinary endeavour that has been enriched by contributions from chemistry, physics, materials science, mechanics and manufacturing engineering. The understanding of the interface (or interphase) in composites is the central point of this interdisciplinary effort. From the early development of composite materials of various nature, the optimization of the interface has been of major importance. While there are many reference books available on composite materials, few of them deal specifically with the science and mechanics of the interface of fiber reinforced composites. Further, many recent advances devoted solely to research in composite interfaces have been scattered in a variety of published literature and have yet to be assembled in a readily accessible form. To this end this book is an attempt to bring together recent developments in the field, both from the materials science and mechanics perspective, in a single convenient volume.The central theme of the book is tailoring the interface properties to optimise the mechanical peformance and structural integrity of composites with enhanced strength/stiffness and fracture toughness (or specific fracture resistance). It deals mainly with interfaces in advanced composites made from high performance fibers, such as glass, carbon, aramid, ultra high modulus polyethylene and some inorganic (e.g. B/W, A12O3, SiC) fibers, and matrix materials encompassing polymers, metals/alloys and ceramics. The book is intended to provide a comprehensive treatment of composite interfaces in such a way that it should be of interest to materials scientists, technologists and practising engineers, as well as graduate students and their supervisors in advanced composites. We hope that this book will also serve as a valuable source of reference to all those involved in the design and research of composite interfaces.The book contains eight chapters of discussions on microstructure-property relationships with underlying fundamental mechanics principles. In Chapter 1, an introduction is given to the nature and definition of interfaces in fiber reinforced composites. Chapter 2 is devoted to the mechanisms of adhesion which are specific to each fiber-matrix system, and the physio-chemical characterization of the interface with regard to the origin of adhesion. The experimental techniques that have been developed to assess the fiber-matrix interface bond quality on a microscopic scale are presented in Chapter 3, along with the techniques of measuring interlaminar/intralaminar strengths and fracture toughness using bulk composite laminates. The applicability and limitations associated with loading geometry and interpretation of test data are compared. Chapter 4 presents comprehensive theoretical analyses based on shear-lag models of the single fiber composite tests, with particular interest being placed on the interface debond process and the nature of the fiber-matrix interfacial bonding. Chapter 5 is devoted to reviewing current techniques of fiber surface treatments which have been devised to improve the bond strength and the fiber-matrix compatibility/stability during the manufacturing processes of composites. The micro-failure mechanisms and their associated theories of fracture toughness of composites are discussed in Chapter 6. The roles of the interface and its effects on the mechanical performance of fiber composites are addressed from several viewpoints. Recent research efforts to augment the transverse and interlaminar fracture toughness by means of controlled interfaces are presented in Chapters 7 and 8.

Book High Performance Composite Materials  Characterization of Carbon Fiber Reinforced Epoxy Matrix Composites with Carbon Nanotubes as Reinforcement Agent Within the Matrix

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.

Book Fiber Reinforced Composites

Download or read book Fiber Reinforced Composites written by Kuruvilla Joseph and published by Woodhead Publishing. This book was released on 2021-03-20 with total page 908 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer-based fibre-reinforced composites FRC's have now come out as a major class of structural materials being used or regarded as substituent's for metals in several critical components in space, automotive and other industries (marine, and sports goods) owing to their low density, strength-weight ratio, and fatigue strength. FRC's have several commercial as well as industrial applications ranging from aircraft, space, automotive, sporting goods, marine, and infrastructure. The above-mentioned applications of FRC's clearly reveal that FRC's have the potential to be used in a broad range of different engineering fields with the added advantages of low density, and resistance to corrosion compared to conventional metallic and ceramic composites. However, for scientists/researchers/R&D's to fabricate FRC's with such potential there should be careful and precise design followed by suitable process development based on properties like mechanical, physical, and thermal that are unique to each application. Hence the last few decades have witnessed considerable research on fibre reinforced composites. Fibre Reinforced Composites: Constituents, Compatibility, Perspectives and Applications presents a widespread all-inclusive review on fibre-reinforced composites ranging from the different types of processing techniques to chemical modification of the fibre surface to enhance the interfacial adhesion between the matrix and fibre and the structure-property relationship. It illustrates how high value composites can be produced by efficient and sustainable processing methods by selecting different constituents [fibres and resins]. Researchers in academia working in composites and accompanying areas [materials characterisation] and industrial manufacturers who need information on composite constituents and how they relate to each other for a certain application will find the book extremely useful when they need to make decisions about materials selection for their products. - Focuses on the different types of FRC's that are currently available (e.g. from polymeric matrices to metallic and ceramic matrices, from carbon fibre to different types of natural fibres and from short to long fibre reinforced), their processing techniques, characterization of different properties, and how to improve the interfacial adhesion between an incompatible fibre and matrix and their applications - Looks at crisis areas such as how to incorporate incompatible fibres and matrices together (e.g. Non-polar polypropylene matrix is not compatible with that of polar natural fibres and hence suitable surface modifications are required to make them compatible with each other) along with low cost processing methods, low density and high strength - Uncovers clarifications to both elementary and practical problems related to the fabrication of FRCs - Schematic representations depicting the interaction between different fibre types and matrices will be provided in some chapters
