Machining processes play an important role in the manufacture of a wide variety of components. While the processes required for metal components are well-established, they cannot always be applied to composite materials, which instead require new and innovative techniques. Machining technology for composite materials provides an extensive overview and analysis of both traditional and non-traditional methods of machining for different composite materials. The traditional methods of turning, drilling and grinding are discussed in part one, which also contains chapters analysing cutting forces, tool wear and surface quality. Part two covers non-traditional methods for machining composite materials, including electrical discharge and laser machining, among others. Finally, part three contains chapters that deal with special topics in machining processes for composite materials, such as cryogenic machining and processes for wood-based composites. With its renowned editor and distinguished team of international contributors, Machining technology for composite materials is an essential reference particularly for process designers and tool and production engineers in the field of composite manufacturing, but also for all those involved in the fabrication and assembly of composite structures, including the aerospace, marine, civil and leisure industry sectors. Provides an extensive overview of machining methods for composite materials Chapters analyse cutting forces, tool wear and surface quality Cryogenic machining and processes for wood based composites are discussed

In recent years, the application of composite materials has increased in various areas of science and technology due to their special properties, namely for use in the aircraft, automotive, defence, aerospace and other advanced industries. Machining composite materials is quite a complex task owing to its heterogenity, and to the fact that reinforcements are extremely abrasive. In modern engineering, high demands are placed on components made of composites in relation to their dimensional precision as well as their surface quality. Due to these potential applications, there is a great need to understand the questions associated with machining composite materials. This book aims to provide the fundamentals and the recent advances in the machining of composite materials (polymers, metals and ceramics) for modern manufacturing engineering. The three parts of the book cover the machining of polymeric, metal and ceramic matrix composites. This book can be used as a text book for the final year of an undergraduate engineering course or for those studying machining/composites at the postgraduate level. It can also serve as a useful work of reference for academics, manufacturing and materials researchers, manufacturing and mechanical engineers, and professionals in composite technology and related industries.

Fibre reinforced polymer (FRP) composites are used in almost every type of advanced engineering structure, with their usage ranging from aircraft, helicopters and spacecraft through to boats, ships and offshore platforms and to automobiles, sports goods, chemical processing equipment and civil infrastructure such as bridges and buildlings. The usage of FRP composites continues to grow at an impessive rate as these materials are used more in their existing markets and become established in relatively new markets such as biomedical devices and civil structures. A key factor driving the increased applications of composites over the recent years is the development of new advanced forms of FRP materials. This includes developments in high performance resin systems and new styles of reinforcement, such as carbon nanotubes and nanoparticles. This book provides an up-to-date account of the fabrication, mechanical properties, delamination resistance, impact tolerance and applications of 3D FRP composites. The book focuses on 3D composites made using the textile technologies of weaving, braiding, knitting and stiching as well as by z-pinning.

The potential application areas for polymer composites are vast. While techniques and methodologies for composites design are relatively well established, the knowledge and understanding of post-design issues lag far behind. This leads to designs and eventually composites with disappointing properties and unnecessarily high cost, thus impeding a wider industrial acceptance of polymer composites. Manufacturing of Polymer Composites completely covers pre- and post-design issues. While the book enables students to become fully comfortable with composites as a possible materials choice, it also provides sufficient knowledge about manufacturing-related issues to permit them to avoid common pitfalls and unmanufacturable designs. The book is a fully comprehensive text covering all commercially significant materials and manufacturing techniques while at the same time discussing areas of research and development that are nearing commercial reality.

Natural fibre composite is an emerging material that has great potential to be used in engineering application. Oil palm, sugar palm, bagasse, coir, banana stem, hemp, jute, sisal, kenaf, roselle, rice husk, betul nut husk and cocoa pod are among the natural fibres reported to be used as reinforcing materials in polymer composites. Natural fibre composites were used in many industries such as automotive, building, furniture, marine and aerospace industries. The advantages of natural fibre composites include low cost, renewable, abundance, light weight, less abrasive and they are suitable to be used in semi or non-structural engineering components. Research on various aspects of natural fibre composites such as characterization, determination of properties and design have been extensively carried out. However, publications that reported on research of manufacture of natural fibre composites are very limited. Specifically, although manufacturing methods of components from natural fibre composites are similar to those of components from conventional fibre composites such as glass, carbon and Kevlar fibres, modification of equipment used for conventional fibre composites may be required. This book fills the gap of knowledge in the field of natural fibre composites for the research community. Among the methods reported that are being used to produce components from natural fibre composites include hand lay-up, compression moulding, filament winding, injection moulding, resin transfer moulding, pultrusion and vacuum bag moulding. This book is also intended to address some research on secondary processing such as machining and laser welding of natural fibre composites. It is hoped that publication of this book will provide the readers new knowledge and understanding on the manufacture of natural fibre composites.

Composite materials have a wide range of applications in aerospace and automotive industries due to the advantage of their tailorability when manufacturing. These materials are manufactured near net shape but post-production machining is required where it cannot be avoided like holes, cutouts and doors to achieve dimensional accuracies and for further assemblies. Oblique machining is one of the important processes as to achieve the above. The machining of composites is different from that of metals due to the anisotropic and inhomogeneity of the material. Because of this nature the machining process becomes complicated. The fiber being abrasive in nature and matrix being soft and weak produce fluctuating forces and make difficult for the cutting process causing tool wear. This research hence concentrates on the oblique machining of Uni-directional carbon fiber reinforced polymer composites (UD-CFRP). The oblique cutting of these UD-CFRP's are carried out at different rake angles and at different fiber orientations i.e. from 0 to 180 to predict the different forces. These results are compared with the numerical results where a finite element model is modeled for these different conditions and are compared with the experimental results. The oblique machining is a 3-dimensional process unlike the orthogonal machining which is a 2-dimensional process. The finite element model is modeled as a single-phase system by considering the material to be equivalent homogeneous material for analysis purpose, which simplifies for force prediction. The results from the experiments and the finite element analysis can be used for further analysis where multiple layers of composite laminates are used with different fiber orientations. The results can also be used to predict the forces for drilling process by considering the drilling process to be combination of the oblique cutting at each point.
