This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long fiber-reinforced thermoplastics have favorable mechanical properties, low manufacturing costs and superior lightweight characteristics. However, the configuration of the reinforcing fibers changes significantly throughout the entire production process, reflected in mechanisms such as fiber attrition, fiber alignment, and fiber matrix separation. The complexity of the process-microstructure-property relationship limits the use of this material class in a wider range of lightweight applications. This work presents a contribution to gain a better understanding of the underlying physics of fiber motion during molding and to obtain a theoretical link between processing and the fiber microstructure. As part of this work, novel characterization techniques were developed to overcome the shortcomings of conventional measurement approaches. The measurement concepts comprise methodologies to characterize the fiber orientation, fiber concentration and fiber length by applying sophisticated techniques, which include combining image processing with micro computed-tomography and optical measurement systems. Applying the developed measurement techniques, a range of experimental studies were conducted to investigate the process-induced fiber microstructure. Plate geometries were injection molded at varying nominal fiber concentrations to investigate fiber matrix separation, fiber alignment, and fiber breakage. The experiments revealed substantial variation in the fiber configuration and correlation between the microstructural properties. The substantial fiber matrix separation and fiber breakage found in this work refute the common assumption of uniform fiber concentration and fiber length in molded parts. Additionally, a new experimental setup based on a Couette rheometer was developed to study fiber length reduction under highly controlled conditions, which isolated the impact of processing conditions on fiber attrition. Finally, the generated experimental data are applied to evaluate models predicting the process-microstructure relationship. All models fail to provide acceptable results and the application of these models as truly predictive tools is limited. It was shown that a holistic approach is necessary to capture the process-induced change in fiber configuration, which necessarily includes the interdependencies of the microstructural properties.

Book Synopsis Industrial X-Ray Computed Tomography by : Simone Carmignato
Download or read book Industrial X-Ray Computed Tomography written by Simone Carmignato and published by Springer. This book was released on 2017-10-18 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.
Book Synopsis Polypropylene Handbook by : József Karger-Kocsis
Download or read book Polypropylene Handbook written by József Karger-Kocsis and published by Springer. This book was released on 2019-03-18 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book extensively reviews Polypropylene (PP), the second most widely produced thermoplastic material, having been produced for over 60 years. Its synthesis, processing and application are still accompanied by vigorous R&D developments because the properties of PP are at the borderline between those of commodity and engineering thermoplastics. Readers are introduced to various tacticities and polymorphs of PP, and their effects on structural properties. Further, the book addresses the control of optical properties using nucleants, provides strategies for overcoming the limited cold/impact resistance of PP, examines in detail the effects of recycling, and presents guidelines for the property modification of PPs through foaming, filling and reinforcing with respect to target applications. Special attention is paid to descriptions and models of properties as a function of morphological variables. Last but not least, the book suggests potential practical applications of PP-based systems, especially in the packaging, appliances, building/construction, textile and automotive sectors. Each chapter, written by internationally respected scientists, reflects the current state-of-art in the respective field and offers a vital source of information for students, researchers and engineers interested in the morphology, properties, testing and modeling of PP and PP-based systems. The content is indispensable to the appropriate application of PPs and related composites.

Book Synopsis Engineered Interfaces in Fiber Reinforced Composites by : Jang-Kyo Kim
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.
