Pultrusion for engineers is a comprehensive overview of the latest developments and applications for this growing and increasingly important area of the fibre reinforced plastics industry.Trevor Starr is well known as a specialist consultant with many year's experience in the FRP world. He has assembled an international panel of distinguished experts to provide the widest possible coverage of the state-of-the-art in novel pultrusion applications and development including many leading US researchers such as Brandt Goldworthy, regarded by many as the father of modern pultrusion.Because this book is one of very few to cover pultrusion, it is essential reading for industrial producers of pultruded profiles, chemical companies producing resins and composite materials specialists eager to reach the new markets in, for example, civil engineering that are rapidly being opened up to design solutions involving pultrusions.

Pultrusion is in principle a simple process to manufacture constant cross sectional fiber reinforced polymer composites. The process has a low labour content and a high raw material conversion efficiency since it is a continuous processing technique. Even if the pultrusion is conceptually quite simple, the analysis of its physics, dynamics and definition of optimal processing parameters, are complex tasks. Keeping the multi-physics and large amount of variables involved in the pultrusion process in mind, a satisfactory experimental analysis for the production requires considerable time which is obviously not a cost-efficient approach. In order to avoid the expensive trial-and-error approaches for designing new products and optimum process conditions, the development of computational process models is needed.This book focuses on the numerical modelling of the pultrusion process. State-of-the-art process models are reviewed and the governing principles are explained in a systematic way. The main challenges in pultrusion such as the process induced residual stresses, shape distortions, thermal history, species conversion, phase changes, impregnation of the reinforcements and pulling force are described and related examples are provided. Moreover, the strategies for having a reliable and optimised process using probabilistic approaches and optimisation algorithms are summarised.Another focus of this book is on the thermo-chemical and mechanical analyses of the pultrusion process for industrial profiles such as rectangular box section, L-shaped profile, I-beam, flat and round profiles in which the process induced stresses and dimensional variations together with the thermal and cure developments are highlighted.

Polymer matrix composites are used extensively across a wide range of industries, making the design and development of effective manufacturing processes of great importance. Manufacturing techniques for polymer matrix composites (PMCs) provides an authoritative review of the different technologies employed in the manufacture of this class of composite.Following an introduction to composites and manufacturing processes, part one reviews the manufacturing of short fiber and nanoparticle based polymer matrix composites, with injection and compression molding examined in depth. Thermoplastic processing is the focus of part two. Sheet forming, fabric thermostamping, filament winding and continuous fiber reinforced profiles are investigated. Part three reviews thermoset processing. A survey of resin transfer molding follows, including vacuum-assisted and compression resin transfer molding. The pultrusion process is then considered, before the book concludes with an investigation into autoclave and out-of-autoclave curing processes in polymer matrix composites.With its distinguished editors and international team of expert contributors, Manufacturing techniques for polymer matrix composites (PMCs) is an essential guide for engineers and scientists working in the field of polymer matrix composites. - Provides an authoritative review of the different technologies employed in the manufacture of polymer matrix composites - Reviews the manufacturing of short fiber and nanoparticle-based polymer matrix composites, with injection and compression molding examined in depth - Examines thermoplastic processing, sheet forming, fabric thermostamping, filament winding and continuous fiber reinforced profiles

The first textbook on the design of FRP for structural engineering applications Composites for Construction is a one-of-a-kind guide to understanding fiber-reinforced polymers (FRP) and designing and retrofitting structures with FRP. Written and organized like traditional textbooks on steel, concrete, and wood design, it demystifies FRP composites and demonstrates how both new and retrofit construction projects can especially benefit from these materials, such as offshore and waterfront structures, bridges, parking garages, cooling towers, and industrial buildings. The code-based design guidelines featured in this book allow for demonstrated applications to immediately be implemented in the real world. Covered codes and design guidelines include ACI 440, ASCE Structural Plastics Design Manual, EUROCOMP Design Code, AASHTO Specifications, and manufacturer-published design guides. Procedures are provided to the structural designer on how to use this combination of code-like documents to design with FRP profiles. In four convenient sections, Composites for Construction covers: * An introduction to FRP applications, products and properties, and to the methods of obtaining the characteristic properties of FRP materials for use in structural design * The design of concrete structural members reinforced with FRP reinforcing bars * Design of FRP strengthening systems such as strips, sheets, and fabrics for upgrading the strength and ductility of reinforced concrete structural members * The design of trusses and frames made entirely of FRP structural profiles produced by the pultrusion process

Offers information on the fundamental principles, processes, methods and procedures related to fibre-reinforced composites. The book presents a comparative view, and provides design properties of polymeric, metal, ceramic and cement matrix composites. It also gives current test methods, joining techniques and design methodologies.

Mechanics of Materials in Modern Manufacturing Methods and Processing Techniques provides a detailed overview of the latest developments in the mechanics of modern metal forming manufacturing. Focused on mechanics as opposed to process, it looks at the mechanical behavior of materials exposed to loading and environmental conditions related to modern manufacturing processes, covering deformation as well as damage and fracture processes. The book progresses from forming to machining and surface-treatment processes, and concludes with a series of chapters looking at recent and emerging technologies. Other topics covered include simulations in autofrettage processes, modeling strategies related to cutting simulations, residual stress caused by high thermomechanical gradients and pultrusion, as well as the mechanics of the curing process, forging, and cold spraying, among others. Some non-metallic materials, such as ceramics and composites, are covered as well. - Synthesizes the latest research in the mechanics of modern metal forming processes - Suggests theoretical models and numerical codes to predict mechanical responses - Covers mechanics of shot peening, pultrusion, hydroforming, magnetic pulse forming - Considers applicability of different materials and processes for optimum performance
