This book was released on 2018-10-18 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tungsten fiber reinforced copper matrix (W/Cu) composites have served as an ideal model system with which to analyze the properties of metal matrix composites. A series of research programs were conducted to investigate the stress-strain behavior of W/Cu composites; the effect of fiber content on the strength, modulus, and conductivity of W/Cu composites; and the effect of alloying elements on the behavior of tungsten wire and of W/Cu composites. Later programs investigated the stress-rupture, creep, and impact behavior of these composites at elevated temperatures. Analysis of the results of these programs as allows prediction of the effects of fiber properties, matrix properties, and fiber content on the properties of W/Cu composites. These analyses form the basis for the rule-of-mixtures prediction of composite properties which was universally adopted as the criteria for measuring composite efficiency. In addition, the analyses allows extrapolation of potential properties of other metal matrix composites and are used to select candidate fibers and matrices for development of tungsten fiber reinforced superalloy composite materials for high temperature aircraft and rocket engine turbine applications. The W/Cu composite efforts are summarized, some of the results obtained are described, and an update is provided on more recent work using W/Cu composites as high strength, high thermal conductivity composite materials for high heat flux, elevated temperature applications.

Download or read book High Temperature Fatigue Behavior of Tungsten Copper Composites written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2019 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high temperature fatigue behavior of a 9 vol percent, tungsten fiber reinforced copper matrix composite was investigated. Load-controlled isothermal fatigue experiments at 260 and 560 C and thermomechanical fatigue (TMF) experiments, both in phase and out of phase between 260 and 560 C, were performed. The stress-strain response displayed considerable inelasticity under all conditions. Also, strain ratcheting was observed during all the fatigue experiments. For the isothermal fatigue and in-phase TMF tests, the ratcheting was always in a tensile direction, continuing until failure. The ratcheting during the out-of-phase TMF test shifted from a tensile direction to a compressive direction. This behavior was thought to be associated with the observed bulging and the extensive cracking of the out-of-phase specimen. For all cases, the fatigue lives were found to be controlled by damage to the copper matrix. Grain boundary cavitation was the dominant damage mechanism of the matrix. On a stress basis, TMF loading reduced lives substantially, relative to isothermal cycling. In-phase cycling resulted in the shortest lives, and isothermal fatigue at 260 C, the longest.

This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of selected alloying elements on the elevated temperature tensile properties of tungsten fiber reinforced composites were studied. Composites were made of copper, copper- 2 percent chromium and copper- 10 percent nickel reinforced with various volume percents of uniaxially oriented tungsten fibers. The composites were tested in tension at temperatures up to 1800 degrees F.A comparison of the elevated-temperature tensile properties of tungsten fiber - copper alloy composites, representing soluble systems, was made with tungsten fiber - copper composites, representing a mutually insoluble system. The effects of alloying on the elevated-temperature tensile properties of tungsten fiber reinforced composites was also studied. A linear relation existed at elevated temperatures between tensile strength and volume percent fiber content for all the systems investigated. The copper alloy composites were weaker in tension at high volume percent fiber contents than copper composites in which alloying with the fiber did not occur. The tensile strength of the alloyed tungsten fiber decreased with increasing penetration of the alloying element into the tungsten fiber.

This book was released on 1993 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high-temperature fatigue behavior of a [0]12 tungsten fiber-reinforced copper matrix composite was investigated. Specimens having fiber volume percentages of 10 and 36 were fatigued under fully reversed, strain-controlled conditions at both 260 and 560°C. The fatigue life was found to be independent of fiber volume fraction because fatigue damage preferentially occurred in the matrix. Also, the composite fatigue lives were shorter at 560°C as compared to 260°C, due to changes in mode of matrix failure. On a total strain basis, the fatigue life of the composite at 560°C was the same as the life of unreinforced copper, indicating that the presence of the fibers did not degrade the fatigue resistance of the copper matrix in this composite system. Comparison of strain-controlled fatigue data to previously generated load-controlled data revealed that the strain-controlled fatigue lives were longer because of mean strain and mean stress effects.

Book excerpt: The concept of reinforcing a material by the use of a fiber is not a new one. The Egyptian brick layer employed the same principle more than three thousand years ago when straw was incorporated into the bricks. More recent examples of fiber reinforced composites are steel-reinforced concrete, nylon and rayon cord reinforced tires, and fiberglass reinforced plastics. In the last several years considerable progress has been made on new composite structures particularly utilizing boron (on tungsten substrate) fibers in various matrices. Many of these advances have been reviewed recently by P. M. Sinclair1 and by Alexander, Shaver, and Withers.2 An excellent earlier survey is available by Rauch Sutton, and McCreight.3 Boron-reinforced epoxy composites are being fabricated and tested as jet engine components, fuselage components, and even as a complete aircraft wing because of the tremendous gain in experimentally demonstrated properties such as modulus, strength, and fatigue resistance, particularly on a weight normalized (e.g., strength/density) basis. Other than glass/epoxy and boron/ epoxy composites and perhaps boron/aluminum, the systems now under study are in the early stages of research and development. These include other boron/metal composites, graphite/polymer, graphite/metal, graphite/graphite, alumina/metal, and aligned eutectic (directionally, solidified) combinations. As Sinclair points out, designers are wary about filamentary composites becausethere is little background information and scant experience.

Book excerpt: Investigations of metal matrix materials reinforced with polycrystalline ceramic and metal fibers are reviewed. The results of parametric studies with model systems and of developmental studies with practical engineering materials are described, and an indication of the future potential of fiber-reinforced composites is presented. Model system studies have demonstrated the feasibility of strengthening metal matrices with continuous and discontinuous fibers. Fiber composite materials have been fabricated that follow a law-of-mixtures behavior at room and elevated temperatures for tensile and stress- rupture applications. The importance of fiber length-to-diameter ratios and orientation and of fiber-matrix bonding and interaction also have been indicated. Results achieved in preliminary attempts to produce engineering materials have been encouraging. The potential of fiber -reinforced metal composite materials is suggested by the excellent strength of materials currently available in fiber form. Increased fiber strength can be A" 33" achieved, which adds further to the advantage of composite materials

Available in PDF, EPUB and Kindle. Book excerpt: Polymer-based fibre-reinforced composites FRC's have now come out as a major class of structural materials being used or regarded as substituent's for metals in several critical components in space, automotive and other industries (marine, and sports goods) owing to their low density, strength-weight ratio, and fatigue strength. FRC's have several commercial as well as industrial applications ranging from aircraft, space, automotive, sporting goods, marine, and infrastructure. The above-mentioned applications of FRC's clearly reveal that FRC's have the potential to be used in a broad range of different engineering fields with the added advantages of low density, and resistance to corrosion compared to conventional metallic and ceramic composites. However, for scientists/researchers/R&D's to fabricate FRC's with such potential there should be careful and precise design followed by suitable process development based on properties like mechanical, physical, and thermal that are unique to each application. Hence the last few decades have witnessed considerable research on fibre reinforced composites. Fibre Reinforced Composites: Constituents, Compatibility, Perspectives and Applications presents a widespread all-inclusive review on fibre-reinforced composites ranging from the different types of processing techniques to chemical modification of the fibre surface to enhance the interfacial adhesion between the matrix and fibre and the structure-property relationship. It illustrates how high value composites can be produced by efficient and sustainable processing methods by selecting different constituents [fibres and resins]. Researchers in academia working in composites and accompanying areas [materials characterisation] and industrial manufacturers who need information on composite constituents and how they relate to each other for a certain application will find the book extremely useful when they need to make decisions about materials selection for their products. - Focuses on the different types of FRC's that are currently available (e.g. from polymeric matrices to metallic and ceramic matrices, from carbon fibre to different types of natural fibres and from short to long fibre reinforced), their processing techniques, characterization of different properties, and how to improve the interfacial adhesion between an incompatible fibre and matrix and their applications - Looks at crisis areas such as how to incorporate incompatible fibres and matrices together (e.g. Non-polar polypropylene matrix is not compatible with that of polar natural fibres and hence suitable surface modifications are required to make them compatible with each other) along with low cost processing methods, low density and high strength - Uncovers clarifications to both elementary and practical problems related to the fabrication of FRCs - Schematic representations depicting the interaction between different fibre types and matrices will be provided in some chapters
