Abrasive waterjet machining (AWJM) is one of the non-traditional machining processes used for machining hard and difficult materials including metal matrix composites (MMCs) and ceramic matrix composites (CMCs). MMCs and CMCs are widely used in the industries such as automobile, aerospace, defense, etc. In AWJM, the material is removed by a narrow stream of high pressure water along with abrasive particles. This work, reviews the research work carried out on the machining aspects of MMCs and CMCs using AJWM. Most of the research work in MMCs is carried out on aluminum based matrix reinforced with ceramics such as silicon carbide (SiC) and aluminum oxide (Al2O3) in various proportions. In the case of CMCs, the research work mostly are carried out on alumina (Al2O3) based work specimen. Generally, it is observed that the reinforcement particles in the MMCs and CMCs greatly influence the output process parameters like depth of the cut, material removal rate (MRR), surface roughness (Ra), kerf width, etc. From the literature review, it is observed that the increase in volume percentage of reinforced abrasive particles results in decreased MRR, decreased in the depth of cut and increase in the Ra. This work also covers the future research work in the machining aspects of MMCs and CMCs.

During the past 25 years materials scientists have been able to make a major change in the way materials are considered for application. In the past designers have worked with data representing the properties of homogeneous, isotropic materials and designed their components to fit written accepted ranges of “design allowables”. More recently, however, the concept of composite materials has permitted almost limitless tailoring of composites to create entirely new designs never previously possible. By choice of types of material constituents, their relative percentages and their orientation the designer can now work closely with the materials scientist to optimize system performance. This philosophy has firmly taken hold in the family of fiber reinforced polymer matrix composites and more recently has made metal matrix composites an industrial reality.

Carbon Based Nanomaterials

Abstract Carbon-based nanomaterials mainly including carbon nanotubes (CNTs), graphene, and graphene oxide (GO) have superior properties of low density, outstanding strength, and high hardness. Compared with ceramic reinforcements, a small amount of carbon-based nanomaterials can significantly improve the mechanical properties of metal matrix composites (MMCs) and ceramic matrix composites (CMCs). However, CNTs and graphite always aggregate or degrade during the fabrication with a high temperature, especially in MMCs. GO has the advantages of easier to be dispersed in other materials and better high-temperature stability. Laser directed energy deposition (DED), has been used to fabricate GO-MMCs and GO-CMCs due to the unique capabilities of coating, remanufacturing, and producing functionally graded materials. Laser DED, as a fusion manufacturing process, could fully melt the material powders, which could refine the microstructure and increase the density and mechanical properties. However, GO could react with matrix materials at high temperatures. The survival, degradation, and reactions of GO in laser DED fabricated GO-MMCs and GO-CMCs are still unknown. There is also no investigation on the reinforcement mechanisms of GO in metal matrix materials and ceramic matrix materials in the laser DED process. In this study, GO reinforced Ti (GO-Ti) and GO reinforced zirconia toughened alumina (GO-ZTA) parts were fabricated by laser DED process. Raman spectrum, XRD analysis, and EDS analysis have been applied to investigate the forms of GO in both DED fabricated GO-MMCs and GO-CMCs. The reinforcement mechanisms of GO on microhardness and compressive properties of MMCs and CMCs have been analyzed.

AbstractSince the 1960s, a new class of Si-based advanced ceramics called polymer-derived ceramics (PDCs) has been widely reported because of their unique capabilities to produce various ceramic materials (e.g., ceramic fibers, ceramic matrix composites, foams, films, and coatings) and their versatile applications. Particularly, due to their promising structural and functional properties for energy conversion and storage, the applications of PDCs in these fields have attracted much attention in recent years. This review highlights the recent progress in the PDC field with the focus on energy conversion and storage applications. Firstly, a brief introduction of the Si-based polymer-derived ceramics in terms of synthesis, processing, and microstructure characterization is provided, followed by a summary of PDCs used in energy conversion systems (mainly in gas turbine engines), including fundamentals and material issues, ceramic matrix composites, ceramic fibers, thermal and environmental barrier coatings, as well as high-temperature sensors. Subsequently, applications of PDCs in the field of energy storage are reviewed with a strong focus on anode materials for lithium and sodium ion batteries. The possible applications of the PDCs in Li-S batteries, supercapacitors, and fuel cells are discussed as well. Finally, a summary of the reported applications and perspectives for future research with PDCs are presented.

A thorough investigation of the microstructure of single SCS-6 SiC fibers widely used as reinforcements in metal-matrix and ceramic-matrix composites has been made. Various techniques of electron microscopy (EM) including scanning (SEM), conventional transmission (TEM), high resolution (HREM), parallel electron energy loss spectroscopy (PEELS), and scanning Auger microscopy (SAM) have been used to analyze and characterize the microstructure. The fiber is a complicated composite consisting of many different layers of SiC deposited on a carbon core and different carbonaceous coatings covering the SiC layers. The structural and chemical aspects of each layer are characterized and discussed.

Nanocarbon Materials

AbstractNanocarbon materials (carbon nanotubes, graphene, graphene oxide, reduced graphene oxide, etc.) are considered the ideal toughening phase of ceramic matrix composites because of their unique structures and excellent properties. The strengthening and toughening effect of nanocarbon is attributed to several factors, such as their dispersibility in the matrix, interfacial bonding state with the matrix, and structural alteration. In this paper, the development state of nanocarbon-toughened ceramic matrix composites is reviewed based on the preparation methods and basic properties of nanocarbon-reinforced ceramic matrix composites. The assessment is implemented in terms of the influence of the interface bonding condition on the basic properties of ceramic matrix composites and the methods used to improve the interface bonding. Furthermore, the strengthening and toughening mechanisms of nanocarbon-toughened ceramic matrix composites are considered. Moreover, the key problems and perspectives of research work relating to nanocarbon-toughened ceramic matrix composites are highlighted.

The present work deals with the characterization of interfacial properties for the development and life prediction of metal matrix and ceramic matrix composites. Advanced non-destructive methods are developed for this endeavour. An innovative micro-mechanics parameter is introduced for evaluating the fibre/matrix interfacial shear stiffness. The interface elastic property both in metal matrix and ceramic matrix composites is determined using the shear-wave back reflectivity (SBR) ultrasonic technique. By means of this approach, the effect of residual radial stresses on the interfacial shear elastic property is quantified. In addition, the interface shear strength is determined in model metal matrix composites by in-situ monitoring of fibre fragmentation using an original ultrasonic technique for imaging fibre breaks of a few micrometers in width. Finally, the interfacial stress at fracture is evaluated in-situ in metal matrix composites using ultrasonic nondestructive monitoring of interfacial deformation and failure under incremental transverse loading of the fibre embedded in the matrix.
