Adaptive structures, embedded with sensors and actuators, have many applications, such as damage detection, structural health monitoring, noise reduction, etc. Recent developments in adaptive composites and their fabrication techniques have focussed on robust metal-matrix and polymer-matrix adaptive structures. Metal-matrix structures are used in applications where structure is required to with...

Metal matrix composite (MMC) technology can improve the service performance of matrix metals and alloys. Most magnesium alloy based MMCs are produced via a casting process, therefore the casting microstructures are of vital importance to their performance in service. The formation of microstructure during solidification of MMCs is mainly influenced by four factors: nucleation (or its absence) o...

Pin-on-disk tests were performed to evaluate the wear behaviour of a 2024 aluminium alloy metal matrix composite (MMC) reinforced with 52 vol.% TiC particles (Al-2024/TiC) in fabricated and thermal-treated (T6) condition. The MMC was produced via pressureless infiltration partially sintered preforms an average particle size 1.1 μm at 1200 °C for 2 h under flowing argon. Microstructural mechanic...

Micro powder injection moulding-μPIM is a powder injection moulding-PIM variant for microparts/devices. This study is about the optimization and respective production of nanocomposites feedstocks suitable to μPIM process. The optimization of MWCNT content in metal matrix composites-MMC feedstock were performed using torque rheometry until achieve homogeneous feedstocks with suitable flowability...

Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...

In this study, discrepancies between the free vibration of fiber-metal laminate (FML) and composite cylindrical shells reinforced by carbon nanotubes (CNTs) based on Love’s first approximation shell theory have been considered by beam modal function model. The representative volume elements consist of three and four phases for composite and FML structures, respectively, which include fiber, CNT...

This review summarises the research work carried out in the field of carbon nanotube (CNT) metal matrix composites (MMCs). Much research has been undertaken in utilising CNTs as reinforcement for composite material. However, CNT-reinforced MMCs have received the least attention. These composites are being projected for use in structural applications for their high specific strength as well as f...
