Book Description
This report presents a cost analysis of Carbon Fiber production from pitch. The process starts with a preparation step that converts the pitch into mesophase pitch. The mesophase pitch is then stabilized and passes through carbonization, graphitization, surface treatment and sizing, before being wound. This report was developed based essentially on the following reference(s): (1) "Fibers, 5. Synthetic Inorganic", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) US Patent 4999099, issued to Conoco in 2011 (3) Chung, D.D.L., Carbon Fiber Composites, 1994 Keywords: Carbon Fiber, Petroleum Pitch, Coal Tar Pitch, Mesophase Pitch

Book Description
This report presents a cost analysis of Carbon Fiber production from polyacrylonitrile (PAN) fiber. In this process, PAN fiber is first stabilized. The stabilized PAN passes then through carbonization, surface treatment and sizing, before being winded. This report was developed based essentially on the following reference(s): (1) "Fibers, 5. Synthetic Inorganic", Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) US Patent 8137810, issued to Toray in 2012; Keywords: Polyacrylonitrile, carbon fiber, acrylic fiber, PAN

Book Description
The purpose of this study was to manufacture and mechanically characterize low-cost carbon fiber derived from pitch-based precursor that meets or exceeds the general-purpose carbon fiber. For this study, isotropic coal-tar pitch precursor was used due to its ease in manufacturing carbon fiber and low-cost starting material. Various analyses such as elemental composition, softening point, TGA, FT-IR, NMR, single carbon fiber testing, and SEM were performed to fully characterize the precursor and carbon fiber. Using melt spinning method, the precursor was melt spun at 235 °C, a pressure of 1.5 MPa and a winding speed of 400 rpm to achieve continuous small diameter fibers known as spun/green fibers. The winding speed of the drum collector and the spinneret diameter controlled the overall diameter of the carbon fibers. The green fibers then underwent the thermal treatment processes of stabilization and carbonization. The green fibers were oxidized at 300 °C with a heating rate of 0.25 °C/min in air. Later, they were carbonized at 1100 °C with a heating rate of 1 °C/min in an inert environment. Experimentally it was determined that smaller diameter carbon fibers were easy to fully oxidize with a smaller heating rate. This also resulted in higher mechanical properties due to less defects in their structures. The isotropic pitch-based carbon fiber manufactured in this study have the maximum tensile strength and elastic modulus of 927 MPa and 86 GPa, respectively.

Book Description
The objective of this study is to investigate the relationship among process, structure, and property of the UTSI pitch-based carbon fibers and optimize carbon fiber's mechanical properties through the stabilization process. Various analysis techniques were employed throughout these investigations which include the Scanning Electron Microscope (SEM), optical microscope, Dia-stron system, MTS, and ImageJ. Several fiber process techniques including fiber spinning, stabilization, and carbonization were explored to determine the effect of the thermal process on the fiber yield, fiber diameter, the sheath-core structure of stabilized fibers, the pac-man and hollow core structures of carbonized fibers, and the resulting mechanical properties of the carbon fibers. It was found that stabilization time and the temperature stepping had a great deal on influence on the resulting carbon fibers. Larger diameter fiber is easy to form sheath-core structure in the stabilization process. Pac-man structure was developed at 600°C during the carbonization. Both stabilization duration and the carbonization temperature control the resulting carbon fiber diameter and fiber structure defects such as the pac-man and hollow core defects. Multi-step stabilization can reduce the total stabilization duration and improve the mechanical properties of the resulting carbon fibers. Fiber structure non-uniformities including fiber diameter distributions for a bundle fiber or along a single fiber, and pac-man angles were determined. Statistical analysis revealed the distribution of the carbon fiber cross-sectional areas and the result is compared against commercial available carbon fibers. Carbon fiber sandwiched composites (CFSCs) were fabricated with UTSI carbon fiber and commercial PAN-based carbon fibers. Several configurations of sandwich structured composites were explored to test the flexural properties with varying sandwich thickness.

Book Description
Finite element modelling of composite materials and structures provides an introduction to a technique which is increasingly being used as an analytical tool for composite materials.The text is presented in four parts: Part one sets the scene and reviews the fundamentals of composite materials together with the basic nature of FRP and its constituents. Two-dimensional stress-strain is covered, as is laminated plated theory and its limitations. Part two reviews the basic principles of FE analysis, starting with underlying theoretical issues and going on to show how elements are derived, a model is generated and results are processed. Part three builds on the basics of FE analysis and considers the particular issues that arise in applying finite elements to composites, especially to the layered nature of the material. Part four deals with the application of FE to FRP composites, presenting analytical models alongside FE representations. Specific issues addressed include interlaminar stresses, fracture delamination, joints and fatigue. This book is invaluable for students of materials science and engineering, and for engineers and others wishing to expand their knowledge of structural analysis. Covers important work on finite element analysis of composite material performance Based on material developed for an MSc course at Imperial College, London, UK Covers particular problems such as holes, free edges with FE results compared with experimental data and classical analysis

Book Description
Advances in engineering precision have tracked with technological progress for hundreds of years. Over the last few decades, precision engineering has been the specific focus of research on an international scale. The outcome of this effort has been the establishment of a broad range of engineering principles and techniques that form the foundation of precision design. Today’s precision manufacturing machines and measuring instruments represent highly specialised processes that combine deterministic engineering with metrology. Spanning a broad range of technology applications, precision engineering principles frequently bring together scientific ideas drawn from mechanics, materials, optics, electronics, control, thermo-mechanics, dynamics, and software engineering. This book provides a collection of these principles in a single source. Each topic is presented at a level suitable for both undergraduate students and precision engineers in the field. Also included is a wealth of references and example problems to consolidate ideas, and help guide the interested reader to more advanced literature on specific implementations.
