Available in PDF, EPUB and Kindle. Book excerpt: The results to date of structural research programs to investigate lightweight, glass-reinforced plastics or composite materials for deep-submergence vehicles are summarized. Of significance from these studies is the need to consider effects attributable to the matrix material and bonding between fibers and matrix, that is, maintaining integrity of the structure in a water environment under high pressure and utilizing hull concepts which lend themselves to shear-sensitive materials. Plans for present and future structural research to study more extensively the use of fiber-reinforced plastic materials for pressure hull applications are also reviewed. (Author).

This book was released on 1968 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large number of models employing a variety of geometric concepts and fabricated from plastic reinforced with glass, carbon, and boron fibers were tested under external hydrostatic pressure. The results were evaluated to explore the feasibility of using filament-reinforced plastics (FRP) as a structural material for the pressure hulls of deep-ocean research vehicles. A concurrent theoretical study indicated that FRP offers the greatest potential for this application at depths greater than 15,000 ft. The test results to date substantiate the basic strength-to-weight advantages of FRP at these depths over other state-of-the-art metals such as HY-140 steel and HY-110 titanium. However, a number of significant problems must be solved or circumvented before this material can be considered acceptable for manned deep-submergence pressure hull applications. These problems include the lack of complete understanding of failure mechanisms; the lack of a verified analysis of the response of thick orthotropic shells of filament-wound materials, principally in regions of complex structural details; the loss of strength due to exposure of cut fibers to a high-pressure environment; the need for development of standardized fabrication procedures adaptable to quality control; and the need for development of nondestructive test techniques which can be used to reliably evaluate the structural integrity of the fabricated hull throughout its service life. A model program (including 1/3-scale models) to determine the feasibility of near-term application of unpenetrated GRP unstiffened and ring-stiffened cylinders with titanium closures has been initiated to find solutions to the above problems.

Download or read book Mechanics of Composite Materials written by F. W. Wendt and published by Elsevier. This book was released on 2013-10-22 with total page 903 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanics of Composite Materials contains the proceedings of the Fifth Symposium on Naval Structural Mechanics held in Philadelphia, Pennsylvania, on May 8-10, 1967. The papers explore the mechanics of composite materials for naval applications. The structural requirements of a system and the fundamental mechanical properties of composite materials, as well as the behavior of such materials under various environmental conditions, are discussed. This book is comprised of 40 chapters and begins with an analysis of missile and aircraft systems constraints and operational requirements, along with ship systems constraints and operational requirements, for composite materials. The following chapters focus on structural uses of composites, particularly in naval ships, aircraft, re-entry vehicles, and space vehicle structures; and the micromechanics, structural mechanics, and failure mechanics of composite materials. Problems in the design of joints and attachments are considered, along with the stability of pre-strained laminated media; environmental factors in the design of composite materials; and the effect of water on glass-reinforced plastics. This monograph will be a useful resource for scientists and engineers who are particularly concerned with the mechanics of composite materials.

Book Synopsis The Nasl Notched Flat Compression Test for Filament Wound Materials. Reinforced Plastics for Deep Submergence and Other High Strength Applications by : N. Fried
Download or read book The Nasl Notched Flat Compression Test for Filament Wound Materials. Reinforced Plastics for Deep Submergence and Other High Strength Applications written by N. Fried and published by . This book was released on 1964 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NASAL notched flat method for determining compressive strength of filament wound materials is described. Data are presented for a series of tests, in which a number of different methods of grip construction were employed, indicating good reproducibility, with an overall coefficient of variation of 4.9%. For a material of 2:1 orthogonal construction, with S glass reinforcement, an average compressive strength value of 157,800 psi was obtained in the stronger ('2') direction. This value is within 5% of the average value reported for tests on cylindrical specimens, of similar construction, tested hydrostatically. Very recent data for a material of superior quality, tested by the NASL notched flat method, gave an average value of compressive strength in the '2' direction of 178,000 psi, with an individual high of 192,800 psi. Based on these data, it is believed that laminates of this type may be produced with present day materials which will have compressive strengths of 200,000 psi or higher. (Author).

Download or read book The Complete Technology Book on Fibre Glass, Optical Glass and Reinforced Plastics written by NIIR Board of Consultants and Engineers and published by ASIA PACIFIC BUSINESS PRESS Inc.. This book was released on 2006-10-01 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. TAGS Fibre Production from Ceramic Crucibles, Production of Fibre Optic Elements, How Optical Fiber is Made, Making Optical Fibers, Optical Fibre Manufacture, Optical Fiber Manufacturing, Manufacturing Optical Components, Optical Component Manufacturing, Optical Component Production, Optical Manufacturing Equipment, Fiber Optic Component and Equipment Manufacturing, Fibre Reinforced Plastic, Fiber Reinforced Plastic Manufacturing Process, Reinforced Plastic Industry, Reinforced Plastic Manufacturing Methods, Reinforced Plastics Production, Reinforced Plastic Manufacturing, Production of Reinforced Plastic, Ophthalmic glass, Reinforced Molding Compounds, Sheet Molding Compound, Laminate Bag Molding Process, Plastics for Aerospace, Plastics in Aircraft, Reinforced Plastics for Transportation on Wheels, Optics Manufacturing Process, Manufacturing Optical Glass, Opthalmic Glass, Manufacturing Optical Fiber, Method for Manufacturing Optical Glass, Manufacture of Optical Fibers, Manufacturing Process of Optical Fibers, Reinforced Plastic Manufacturing Plant, Blowing Wool Insulation, Blowing Wool Fiberglass Insulation, Fiberglass Blowing Wool Insulation, Fiber Glass Blowing Wool, Construction Fiberglass, Fiberglass in Wall Construction, Thermal Insulation Metal Buildings, Fabricated Fibre Glass Duct, Equipment Insulation, Marine Equipment Insulation, Marine Products, Ceramic Fibre Papers, Ceramic Fibre Textiles, Bulk Fibres, Paints, Varnishes and Solvents, Filtration of Hydraulic Oil, Filteration of Swimming Pool Water, Glass Fibre Paper, Co-Polymer Composition, Polymerization Process, Commercial Polymerization Process, Continuous Filament Fibre Forming Methods, Fibre Drawing, Falcon Window Frame Moldings, Matched Die Molding-Fabric, Mat and Preform, Filament Winding, Filament Winding Machines, Pyrolyzed and Graphitized Plastics, Boat Construction, NPCS, Niir, Process Technology Books, Business Consultancy, Business Consultant, Project Identification and Selection, Preparation of Project Profiles, Startup, Business Guidance, Business Guidance to Clients, Startup Project, Startup Ideas, Project for Startups, Startup Project Plan, Business Start-Up, Business Plan for Startup Business, Great Opportunity for Startup, Small Start-Up Business Project, Best Small and Cottage Scale Industries, Startup India, Stand Up India, Small Scale Industries, New Small Scale Ideas for Optics Manufacturing Industry, Fibre Production Business Ideas You Can Start on Your Own, Indian Optical Fiber Manufacturing Industry, Small Scale Optics Manufacturing, Guide to Starting and Operating Small Business, Business Ideas for Reinforced Plastic Manufacturing, How to Start Reinforced Plastic Manufacturing Business, Starting Optical Fiber Manufacturing, Start Your Own Reinforced Plastic Manufacturing Business, Optical Fiber Production Business Plan, Business Plan for Fibre Production, Small Scale Industries in India, Optical Fiber Manufacturing Based Small Business Ideas in India, Small Scale Industry You Can Start on Your Own, Business Plan for Small Scale Industries, Set Up Optics Manufacturing, Profitable Small Scale Manufacturing, How to Start Small Business in India, Free Manufacturing Business Plans, Small and Medium Scale Manufacturing, Profitable Small Business Industries Ideas, Business Ideas for Startup
