Download or read book Fracture Characterization of Recycled HDPE Nanoclay Composites written by Suk Joon Na and published by . This book was released on 2016 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: High density polyethylene (HDPE) is one of the most widely used engineering plastics in infrastructures, particularly in a pipeline system. Current HDPE pipes are made from pristine resin which directly relies on petroleum supply. Utilizing recycled HDPE to replace a portion of pristine resin certainly provides benefits in improving the sustainability of the HDPE pipes and saving raw materials. However, challenges still remain to apply the recycled material for engineering applications which specifically require the long-term service life performance. Recycled materials generally possess inferior material properties to the pristine counterpart, and they have a higher risk of failure caused by stress cracking within a desired lifetime. To suggest a solution to the concern, this research focuses on a new class of materials which are polymer/nanoclay composites (PNCs). The presence of a small amount of nanoclay significantly enhances the properties by increasing mechanical properties, flammability resistance and surface scratch resistance while decreasing gas permeability. However, the fracture resistance of the recycle-based PNCs, particularly stress crack resistance (SCR), has not been studied yet. This research therefore evaluates the effect of nanoclay on the short-term and long-term fracture resistance of pristine/recycled HDPE pipe material. The short-term fracture resistance was characterized using the essential work of fracture (EWF) concept test. The results revealed that nanoclay has not produced significant toughening effect and causes embrittlement of the materials. Adding nanoclay to pristine HDPE, a steady decrease in fracture toughness was measured until 4-wt% of nanoclay after which the change was insignificant. Conversely, nanoclay content more than 2-wt% in recycle-blends greatly decreased the fracture toughness value. The long-term SCR via slow crack growth (SCG) mechanism was evaluated by means of the Notched Constant Ligament Stress (NCTL) test. The result revealed that, unlike the short-term fracture resistance, the nanoclay enhanced SCR and extended the failure time. By integrating the short-term and long-term failure behavior employing the elastic-plastic fracture mechanics, a correlation between the fracture toughness and SCG was accomplished in this study.

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.

Download or read book Interfacial Bonding Characteristics in Natural Fiber Reinforced Polymer Composites written by Senthilkumar Krishnasamy and published by Springer Nature. This book was released on 2024-01-17 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general overview of the importance of fibre-matrix interfacial bonding characteristics in natural fibre-based composites to obtain optimal material properties for a specific application. Composites materials are prepared by combining fibres and polymers to achieve superior materials properties than those of the individual components. Composite materials are used to produce lightweight components with increased stiffness and strength; their properties can also be tailored for any specific applications. The glass fibre reinforced composites dominate 95% of the thermoplastic and thermoset-based composites. However, the natural fibre reinforced composites can give competition to the glass fibres due to their advantages such as biodegradability, low density, low cost, and good mechanical properties. This book looks into biocomposites and its important aspect of optimization of materials’ performance by fine-tuning the fibre-matrix bonding characteristics. The chapters in the book look at different plant fibres such as kenaf, pineapple leaf, jute, date palm, luffa, cotton, hemp, wood, bamboo, flax, and straw and the different approaches to enhance the fibre-matrix interfacial bonding through physical and/or chemical treatment methods. It demonstrates that the nature of fibre-matrix bonding has a significant effect on the properties such as tensile, flexural, impact, inter-laminar shear strength, moisture absorption, thickness swelling, thermal, chemical, damping, creep, and fatigue. Its content appeals to academics, students, researcher, and scientist who are working in the field to produce biodegradable and recyclable materials in the composite industry.

Available in PDF, EPUB and Kindle. Book excerpt: Thoroughly revised edition of the classic text on polymer processing The Second Edition brings the classic text on polymer processing thoroughly up to date with the latest fundamental developments in polymer processing, while retaining the critically acclaimed approach of the First Edition. Readers are provided with the complete panorama of polymer processing, starting with fundamental concepts through the latest current industry practices and future directions. All the chapters have been revised and updated, and four new chapters have been added to introduce the latest developments. Readers familiar with the First Edition will discover a host of new material, including: * Blend and alloy microstructuring * Twin screw-based melting and chaotic mixing mechanisms * Reactive processing * Devolatilization--theory, mechanisms, and industrial practice * Compounding--theory and industrial practice * The increasingly important role of computational fluid mechanics * A systematic approach to machine configuration design The Second Edition expands on the unique approach that distinguishes it from comparative texts. Rather than focus on specific processing methods, the authors assert that polymers have a similar experience in any processing machine and that these experiences can be described by a set of elementary processing steps that prepare the polymer for any of the shaping methods. On the other hand, the authors do emphasize the unique features of particular polymer processing methods and machines, including the particular elementary step and shaping mechanisms and geometrical solutions. Replete with problem sets and a solutions manual for instructors, this textbook is recommended for undergraduate and graduate students in chemical engineering and polymer and materials engineering and science. It will also prove invaluable for industry professionals as a fundamental polymer processing analysis and synthesis reference.
