Sheet forming is the most common process used in metal forming and is therefore constantly being adapted or modified to suit the needs of forming composite sheets. Due to the increasing availability of various types of fibre reinforced polymeric sheets, especially with thermoplastic matrices, the scope of use of such materials is rapidly expanding in the automobile, building, sports and other manufacturing industries beyond the traditional areas of aerospace and aircraft applications. This book contains twelve chapters and attempts to cover different aspects of sheet forming including both thermoplastic and thermosetting materials. In view of the expanded role of fibre reinforced composite sheets in the industry, the book also describes some non-traditional applications, processes and analytical techniques involving such materials.The first chapter is a brief introduction to the principles of sheet metal forming. The next two chapters introduce the various forms of materials, manufacturing techniques and the fundamentals of computer simulation. Chapter 4 describes the different aspects of thermoforming of continuous fibre reinforced thermoplastics and the following chapter studies the shear and frictional behaviour of composite sheets during forming. Chapter 6 explores the possibility of applying the grid strain analysis method in continuous fibre reinforced polymeric sheets. The next two chapters address fundamental concepts and recent developments in finite element modelling and rheology. Chapter 9 introduces the theory of bending of thermoplastic composite sheets and shows a novel way of determining both longitudinal and transverse viscosities through vee-bend tests. A significant expansion in the usage of composite materials is taking place in biomedical areas. Chapter 10 discusses the thermoforming of knitted fabric reinforced thermoplastics for load bearing and anisotropic bio-implants. The final chapter introduces roll forming, a commonly used rapid manufacturing process for sheet metals, and discusses the possibility of applying it economically for continuous reinforced thermoplastic sheets.

Thermoplastic matrix composites have attracted much attention in the composites industry due to their easy processibility and improved impact properties. Although there are many books on thermoplastic composites available, none emphasize flexible towpregs and their composite properties. This book discusses various methods of manufacturing flexible towpregs, their properties, their textile preforming behavior, the properties of textile preform, and the properties of final composites. FEATURES Gives readers a complete view of composite manufacturing Offers details on flexible prepregs that other books overlook, such as manufacturing methods, influence of processing parameters, and properties Includes explanations that cover all steps of manufacturing with examples Features case studies and homework exercises for all chapters to reinforce understanding Provides technological information, discussion, and analysis of problems related to all types of flexible towpregs, such as commingling, electrostatic powder coating, wrapped hybrid yarns, micro-braided hybrid yarns, core-spun hybrid yarns, and others This book is aimed at readers working with composite materials, industrial textiles, and related areas to understand the significance of thermoplastic composites made through textile performance of flexible towpregs.

Textile composites encompass a rather narrow range of materials, based on three-dimensional reinforcements produced using specialist equipment. This book describes the design, manufacture and applications of textile composites. The intention is to describe the broad range of polymer composite materials with textile reinforcements, from woven and non-crimp commodity fabrics to 3-D textiles and their applications. The book gives particular attention to the modelling of textile structures, composites manufacturing methods, and subsequent component performance. This practical book is an invaluable guide for manufacturers of polymer composite components, end-users and designers, structural materials researchers, and textile manufacturers involved in the development of new products with textile composites.

My heart sank when I was approached by Dr Hastings and by Professor Briggs (Senior Editor of Materials Science and Technology and Series Editor of Polymer Science and Technology Series at Chapman & Hall, respectively) to edit a book with the provisional title Handbook of Poly propylene. My reluctance was due to the fact that my former book [1] along with that of Moore [2], issued in the meantime, seemed to cover the information demand on polypropylene and related systems. Encour aged, however, by some colleagues (the new generation of scientists and engineers needs a good reference book with easy information retrieval, and the development with metallocene catalysts deserves a new update!), I started on this venture. Having some experience with polypropylene systems and being aware of the current literature, it was easy to settle the titles for the book chapters and also to select and approach the most suitable potential contributors. Fortunately, many of my first-choice authors accepted the invitation to contribute. Like all editors of multi-author volumes, I recognize that obtaining contributors follows an S-type curve of asymptotic saturation when the number of willing contributors is plotted as a function of time. The saturation point is, however, never reached and as a consequence, Dear Reader, you will also find some topics of some relevance which are not explicitly treated in this book (but, believe me, I have considered them).

Models and experiments for faster, less expensive manufacture of thermoplastic partsFocused on simulating thermal defects in thermoplasticsTechniques for better molds, tooling and equipment Book explains methods and coding to create FEM-based models to optimize process variables and predict dimensional distortions during the manufacture of thermoplastic matrix composite parts. After investigating defects, such as spring-in, caused by thermal inconsistencies during manufacture, the text offers a step-by-step approach to simulating and predicting the magnitude of distortion via readily available FE codes. Models are validated by testing using the example of a multi-staged roll-formed continuous thermoplastic woven laminate, which can be readily extended to a variety of mold geometries. Information in this book is intended to reduce the need for costly and time-consuming re-tooling in thermoplastic parts design.
