This report presents a cost analysis of High Density Polyethylene (HDPE) bimodal production from polymer grade (PG) ethylene and 1-hexene using a slurry loop process. The process described is similar to Chevron Phillips’ MarTECH Advanced Dual Loop (ADL) technology and INEOS Innovene S processes. In this study, the polymerization reaction yielding bimodal HDPE is carried out in a dual loop reactor. This report was developed based essentially on the following reference(s): (1) US Patent 9340629, issued to Chevron in 2016 (2) US Patent 7629421, issued to Chevron in 2009 Keywords: Ethene, PE, Loop Reactor, Slurry Reactor, Copolymer
Composite materials are used as substitutions of metals/traditional materials in aerospace, automotive, civil, mechanical and other industries. The present book collects the current knowledge and recent developments in the characterization and application of composite materials. To this purpose the volume describes the outstanding properties of this class of advanced material which recommend it for various industrial applications.
Composites are a class of material, which receives much attention not only because it is on the cutting edge of active material research fields due to appearance of many new types of composites, e.g., nanocomposites and bio-medical composites, but also because there are a great deal of promises for their potential applications in various industries ranging from aerospace to construction due to their various outstanding properties. This book mainly deals with fabrication and property characterization of various composites by focusing on the following topics: functional and structural nanocomposites, numerical and theoretical modelling of various damages in long fiber reinforced composites and textile composites, design, processing and manufacturing technologies and their effects on mechanical properties of composites, characterization of mechanical and physical properties of various composites, and metal and ceramic matrix composites. This book has been divided into five sections to cover the above contents.
This book contains eight chapters that discuss the manufacturing methods, surface treatment, composite interfaces, microstructure-property relationships with underlying fundamental physical and mechanical principles, and applications of carbon fibers and their composites. Recently, carbon-based materials have received much attention for their many potential applications. The carbon fibers are very strong, stiff, and lightweight, enabling the carbon materials to deliver improved performance in several applications such as aerospace, sports, automotive, wind energy, oil and gas, infrastructure, defense, and semiconductors. However, the use of carbon fibers in cost-sensitive, high-volume industrial applications is limited because of their relatively high costs. However, its production is expected to increase because of its widespread use in high-volume industrial applications; therefore, the methods used for manufacturing carbon fibers and carbon-fiber-reinforced composites and their structures and characteristics need to be investigated.

For some time there has been a strong need in the plastic and related industries for a detailed, practical book on designing with plastics and composites (reinforced plastics). This one-source book meets this criterion by clearly explaining all aspects of designing with plastics, as can be seen from the Table of Contents and Index. It provides information on what is ahead as well as today's technology. It explains how to interrelate the process of meeting design performance requirements with that of selecting the proper plastic and manufacturing process to make a product at the lowest cost. This book has been prepared with an awareness that its usefulness will depend greatly upon its simplicity. The overall guiding premise has therefore been to provide all essential information. Each chapter is organized to best present a methodology for designing with plastics and composites. of industrial designers, whether in engineering This book will prove useful to all types or involved in products, molds, dies or equipment, and to people in new-product ventures, research and development, marketing, purchasing, and management who are involved with such different products as appliances, the building industry, autos, boats, electronics, furniture, medical, recreation, space vehicles, and others. In this handbook the basic essentials of the properties and processing behaviors of plastics are presented in a single source intended to be one the user will want to keep within easy reach.
The 5th International Congress on Design and Modeling of Mechanical Systems (CMSM) was held in Djerba, Tunisia on March 25-27, 2013 and followed four previous successful editions, which brought together international experts in the fields of design and modeling of mechanical systems, thus contributing to the exchange of information and skills and leading to a considerable progress in research among the participating teams. The fifth edition of the congress (CMSM ́2013), organized by the Unit of Mechanics, Modeling and Manufacturing (U2MP) of the National School of Engineers of Sfax, Tunisia, the Mechanical Engineering Laboratory (MBL) of the National School of Engineers of Monastir, Tunisia and the Mechanics Laboratory of Sousse (LMS) of the National School of Engineers of Sousse, Tunisia, saw a significant increase of the international participation. This edition brought together nearly 300 attendees who exposed their work on the following topics: mechatronics and robotics, dynamics of mechanical systems, fluid structure interaction and vibroacoustics, modeling and analysis of materials and structures, design and manufacturing of mechanical systems. This book is the proceedings of CMSM ́2013 and contains a careful selection of high quality contributions, which were exposed during various sessions of the congress. The original articles presented here provide an overview of recent research advancements accomplished in the field mechanical engineering.
Handbook of Nonwovens, Second Edition updates and expands its popular interdisciplinary treatment of the properties, processing, and applications of nonwovens. Initial chapters review the development of the industry and the different classes of nonwoven material. The book then discusses methods of manufacture such as dry-laid, wet-laid, and polymer-laid web formation. Other techniques analyzed include mechanical, thermal, and chemical bonding, as well as chemical and mechanical finishing systems. The book concludes by assessing the characterization, testing, and modeling of nonwoven materials.Covering an unmatched range of materials with a variety of compositions and manufacturing routes, this remains the indispensable reference to nonwovens for designers, engineers, materials scientists, and researchers, particularly those interested in the manufacturing of automotive, aerospace, and medical products. Nonwovens are a unique class of textile material formed from fibers that are bonded together through various means to form a coherent structure. The range of properties they can embody make them an important part of a range of innovative products and solutions, which continues to attract interest from industry as well as academia. - Describes in detail the manufacturing processes of a range of nonwoven materials - Provides detailed coverage of the mechanical and thermal properties of non-woven fabrics - Includes extensive updates throughout on the characterization and testing of nonwovens - Explains how to model nonwoven structures
