Book Description
Military use of advanced polymer matrix composites (PMC)â€"consisting of a resin matrix reinforced by high-performance carbon or organic fibersâ€"while extensive, accounts for less that 10 percent of the domestic market. Nevertheless, advanced composites are expected to play an even greater role in future military systems, and DOD will continue to require access to reliable sources of affordable, high-performance fibers including commercial materials and manufacturing processes. As a result of these forecasts, DOD requested the NRC to assess the challenges and opportunities associated with advanced PMCs with emphasis on high-performance fibers. This report provides an assessment of fiber technology and industries, a discussion of R&D opportunities for DOD, and recommendations about accelerating technology transition, reducing costs, and improving understanding of design methodology and promising technologies.

Book Description
Metal Matrix Composites by Friction Stir Processing discusses the capabilities of utilizing friction stir processing (FSP) as a tool to manufacture new materials, such as composites. FSP is considered a tool for grain refinement. However, this work illustrates how FSP has a wider capability due to the material flow and mixing the process offers. This book highlights such aspects by demonstrating the ability of the process to incorporate a second phase and make metal matrix composites (MMCs). The book covers the current research on processing MMCs by FSP, and presents a novel approach of making ductile MMCs by FSP using metal particle reinforcements. - Demonstrates how friction stir processing can be used to make metal matrix composites - Includes a review of different approaches of making metal matrix composites by friction stir processing - Demonstrates the utility of friction stir processing in making new types of non-equilibrium ductile composites - Provides a comparison of properties of friction stir processed composites to those of conventional metal matrix composites

Book Description
This book covers several aspects of the synthesis of composites by the pressureless infiltration technique. It describes the methods used to obtain green preforms, such as cold pressed and hot sintering, describing the heating time, load, and time required for pressing the preforms. Additionally, wettability phenomena, which is directly related on infiltration, is extensively described. Wettability process and interfacial reactions are analyzed in many ceramic-metal systems prior to fabricate the composites. A complete description of fabrication processes for Metal Matrix Composites is included. An extensive section on structural, chemical, and mechanical characterization of composites fabricated with aluminum and magnesium alloys as matrices reinforced with titanium carbide (TiC), aluminum nitride (AlN), silicon carbide (SiC) and alumina (Al2O3) is included. Relevant techniques for joining composites, such as welding and brazing are addressed. As well as issues pertaining to the corrosion and wear of composites are discussed as well. Corrosion behavior of some composites exposed to aqueous media was analyzed. Corrosion of composites using TiC and SiC like reinforcement and Al, Ni, and some Al-Cux, Al-Mgx and Al-Cu-Li alloys like matrix is discussed extensively. The structural characterization techniques addressed include: scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), optical microscopy (OM), differential thermal analysis (DTA), high resolution transmission electron microscopy (HRTEM), and thermogravimetry analysis (TGA). Mechanical testing including hardness, elastic modulus, tension tests, and impact tests were used in the characterization of composites. Theoretical models for prediction of some mechanical properties are included too.

Book Description
This handbook examines the recent advances in the nanotechnology of polymers and ceramics, which possess outstanding mechanical properties and compatibility given their unique physical and chemical properties caused by the unusually large surface area to volume ratios and high interfacial reactivity. This handbook highlights the various compositions and morphologies of polymer and ceramic nanomaterials that can serve as powerful tools for the diverse applications in areas such as electronics, photonics, shape-memory alloys, biomaterials and biomedical nanomaterials, graphene-based technologies, and textiles and packaging. The handbook addresses safety, economics, green production and sustainability. The book contains a section on functionalization of these molecules, which only increases the possibility of developing even more versatile materials that can be fine-tuned for specific applications. Filling a gap in the literature, this handbook provides comprehensive coverage of properties, fabrication, characterization, functionalization methods and applications at both experimental and theoretical models scales. Economic, toxicological, regulatory, and environmental concerns regarding applications are also discussed in detail. Special attention is paid to sustainable approaches that reduce costs in terms of chemicals and time consumption. The book covers research trends, challenges, and prospective topics as well.
