The Manufacturing Technology Of Continuous Glass Fibres

Fibre Science and Technology is one of six titles in a coherent and definitive series of volumes dedicated to advanced composite materials research, development and usage in the former Soviet Union. Much of the information presented has been classified until recently. Thus each volume provides a unique insight into hitherto unknown research and development data. This volume deals with the basic components of a composite material, namely the reinforcement and the encasing matrix material. Beginning with a specification of a range of reinforcing fibres (glass, carbon, organic, inorganic, ceramic), the book then considers in detail the development of such fibres and the significant range of properties achieved. An extensive test methodology used to evaluate the physical and mechanical properties of each type of fibre matrix combination is presented, and the production method employed for each constituent part is described. This book will be of interest to anyone involved in research or development in composite materials science and technology, both in industry and universities.

Although many natural materials were used in the past by man, answering his instinctive urges to prevent heat loss from or entry into his dwellings, no material in modern technology has satisfied the all around requirements as has fiber Glass. Fiber glass, optical glass and reinforced plastics have important applications and uses in the making of various products. Fiberglass is a lightweight, extremely strong, and robust material. Although strength properties are somewhat lower than carbon fiber and it is less stiff, the material is typically far less brittle, and the raw materials are much less expensive. Its bulk strength and weight properties are also very favorable when compared to metals, and it can be easily formed using molding processes. Fibre glass behaves as a thermal insulation because of its entrapment of small cells of air, and prevention of movement of the air in those cells. In acoustical applications, fibre glass presents to advancing sound waves a myriad of small anechoic chambers which reflect the sound inward from many diverse surfaces until it becomes blotted out. Optical glass is a high glass material that has been seen specifically formulated to posses certain desirable characteristics that effect the propagation of light. The two primary parameters that define the basic types of optical glass are its refractive index and its dispersion. Transportation on wheel is of special significance to the reinforced plastics industry on a number of counts. Suppliers of reinforced plastics parts are often called upon to furnish prototypes of products being considered for auto, truck and bus applications. Performance and quality demands on materials used in aerospace vehicles have given rise to many plastics developments and have kept profits in the plastics industry at a higher level than those in other major markets. Some of the fundamentals of the book are fibres based on natural polymers: fibres based on synthetic polymers, fibre glass blown wool or insulation products and their applications, fibre glass in wall construction for reduced sound transmission, ceramic fibre papers, ceramic fibre textiles, commercial polymerization processes, continuous filament fibre forming methods, marine applications, reinforced plastics for transportation on wheels, plastics in aircraft and aerospace, structural laminate bag molding process, reinforced molding compounds, filament winding, etc. The present book contains processes and other valuable information for fiber glass, optical glass and reinforced plastics. This is very resourceful book for entrepreneurs, technocrats, institutions, researches etc.

Fiberglass and Glass Technology: Energy-Friendly Compositions and Applications provides a detailed overview of fiber, float and container glass technology with special emphasis on energy- and environmentally-friendly compositions, applications and manufacturing practices which have recently become available and continue to emerge. Energy-friendly compositions are variants of incumbent fiberglass and glass compositions that are obtained by the reformulation of incumbent compositions to reduce the viscosity and thereby the energy demand. Environmentally-friendly compositions are variants of incumbent fiber, float and container glass compositions that are obtained by the reformulation of incumbent compositions to reduce environmentally harmful emissions from their melts. Energy- and environmentally-friendly compositions are expected to become a key factor in the future for the fiberglass and glass industries. This book consists of two complementary sections: continuous glass fiber technology and soda-lime-silica glass technology. Important topics covered include: o Commercial and experimental compositions and products o Design of energy- and environmentally-friendly compositions o Emerging glass melting technologies including plasma melting o Fiberglass composite design and engineering o Emerging fiberglass applications and markets Fiberglass and Glass Technology: Energy-Friendly Compositions and Applications is written for researchers and engineers seeking a modern understanding of glass technology and the development of future products that are more energy- and environmentally-friendly than current products.

Glass Fibre Reinforcements form the foundation of a composites industry with a global annual production of greater than 10 million tons of high performance, light-weight materials. Possibly the most critical component involved in the manufacture of glass fibres and their composites is the fibre surface coating (or size). Yet because of the intense level of industrial secrecy around size formulations there are very few people in the vast chain of composite materials suppliers, processors and end users who have more than a superficial understanding of these coatings. Many questions are raised about glass fibre size by this large and growing composite community. But the most frequently asked is “what is actually in the size on this glass fibre product?” There is only one source of openly available information on commercial size formulations and that is the patents of the glass fibre manufacturers. This book contains analysis of more than 500 examples of patented size formulations many of which are probably still in use in commercial glass fibre production. The information is tabulated to allow readers to easily identify the similarities and differences between the sizes and their glass fibre products developed for different composite end-use applications, different composite processing techniques, and compatibility with different polymers. Also included is a chapter discussing how patents and their associated information can be used to gain insight into which size formulations may actually be in use in glass fibre production.List of Chapter Titles• Introduction • Sizes And Sizing In Glass Fibre Production• Size Formulations In Patents• Size Patents Of Owens Corning• Size Patents Of Vetrotex• Size Patents Of PPG Fiber Glass• Size Patents From Other Companies• Glass Fibre Product Identification• Conclusions From This Review244 pages, 13 Figures, 131 Tables, 5 Appendices

Engineered composites materials display superior properties to pristine materials. Glass fibres have been used for years in the production of light weight composites. This book is a much needed update as to the processing methods and technologies present in the manufacturing of GFRP. Coverage of machining, cutting, tools, and thermal loads are discussed. Ideal for researchers in academia and industry.

This book highlights recent developments in fiberglass research and technology development, including high-performance fiberglass chemistry; in-depth glass network structure information derived from the-state-of-the-art spectroscopic measurements, molecular dynamics simulations, and their correlations with properties; fiber surface chemistry in relation to sizing chemistry - a critical part of composite performance; fiber process stability; fundamental understanding of the batch-to-melt conversion processes and melt flow simulations; and environmental concerns such as energy efficiency and emission of volatile species, which are key to environmentally-friendly product manufacturing. The book aims to guide fiberglass researchers and manufacturers towards better awareness and, perhaps, provides potential options for global ecosystem management. More than 500 current references are included, which will enable researchers from fiber glass industry and research institution access to the most recent progress in fiberglass science and technology. Advances scientific understanding of fiberglass-forming processes, rising in popularity as a building material throughout the world; Describes the current advances in the structure and formation of fiber glass, beginning with chemistry, a wide range of characterizations, and processes, through to applications; Contains information on environmental aspects of fiberglass production, addressing energy consumption and emission.

The part of this book covering pathogensis and modes of action begins with a chapter on the physicochemical properties of asbestos fibers and a chapter on the deposition and retention of fibers within the lung and their clearance. Some of the effects of asbestos can be reproduced in animal experiments, and the book includes a full review of the results from animal studies using various routes of administration of fibers. It is also generally accepted that the effects of fibers on pulmonary macrophages is central to all fiber-induced pathology, and the release of macrophage-associated inflammatory and immunological mediatros is dealt with in a further chapter. Examination of pathogenicity by cell culture is described, and areas covered include the role of free radicals and cellular mechanisms in producing genetic damage. The fiber-induced activation of some second messenger pathways is also described, with consideration of whether or not similar cellular mechanisms are responsible for all the clinical conditions associated with fiber exposure. Knowledge of the mechanisms involved should be valuable in the development of safe fibers and the prevention of human exposure to new materials that are dangerous as asbestos. The final chapters expound and resolve the conflicts in evidence, discuss the importance of fibers for human well-being and the possible health impact on nonmineral alternatives, and evaluate risks to the public
