In the recent era, Metal Matrix Composites (MMCs) are one of the most vigorously studied topics in material science. Lightweight metals and its alloys create an intense attraction for tailoring new metal matrix composites to overcome conventional limitations like low strength. Aluminum metal matrix composites signify to the high-grade lightweight high-performance aluminum-based MMCs. The reinforcements in aluminum matrix composites could be in the form of particulates, whiskers, and continuous fiber or discontinuous fiber, where weight or volume fraction varies from a few percentages to 60%. Properties of aluminum metal matrix composites can be customized as per the demand of the industry by getting the appropriate combination of the metal matrix, reinforcements, and selective processing route. Nowadays many grads of aluminum matrix composites are fabricated by different routes where in situ route processing is more attractive compared with conventional ex-situ process because it delivers excellent wettability, thermally stability of reinforcements, the bonding strength between reinforcements and matrix, cohesive atomic structure, and fine grain size of reinforcements (specifically nano size). The devoted research work of aluminum matrix composites during the last three-decade generates a wealth of knowledge on the effect of reinforcements vis-à-vis mechanical, chemical, tribological properties of aluminum matrix composites. The acceptance of the aluminum matrix composites as engineering materials depends not only on the performance advantages of the composites, but it also depends upon the cheap, easy, and familiar fabrication technologies for these tailored materials.

“…Silica has several applications in electronic parts of printer toners and the pharmaceutical industry. Al matrix composites with silica reinforcement usually exhibit superior mechanical properties compared to monolithic materials, particularly in severe working conditions such as elevated temperatures [1,8,9]. On the other hand, among one-dimensional nanostructured materials, silica nanotubes (SNTs) have been extensively used in catalysis, biosensor, nanoscale electronics, storage and delivery systems due to important features of accessibility, biocompatibility and photoluminescence [10].…”

Physical properties and processing parameters of the reinforcing phase such as shape and content can dramatically influence the mechanical properties of the composites. In this project, the effect of different shapes of silicon dioxide or silica (SiO2) reinforcement including nanoparticle and nanotube as well as their weight percent (1, 3, 5 and 10 wt %) on the mechanical properties of aluminum (Al) composite were investigated. The silica nanotubes (SNTs) were prepared by hydrothermal methods. In order to achieve a good dispersion, Al powders were coated by cetyl trimethyl ammonium bromide (CTAB) to obtain a surface positive charge. Then, SiO2–Al powders were obtained by electrostatic self-assembly to realize the homogeneous adsorption of SiO2 nano reinforcement on Al powders. Finally, SiO2-reinforced Al matrix composites were fabricated by powder metallurgy. Characterization of composites was carried out by transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM) and Fourier transform infrared spectroscopy (FTIR). For determination of the mechanical properties of the composite, the compressive strength and density were investigated.Results showed a significant reduction in the relative density from 98% to 84% for composites containing 0 to 10 wt % of SiO2. The compressive strength exhibited a moderate increase by adding SNTs while in samples containing SiO2 nanoparticles, the mechanical properties improved and reached a peak value of 225 MPa at 5 wt % SiO2 nanoparticles (~40% increase compared to pure Al). However, a further increase in nanotubes content resulted in a considerable reduction in compressive strength. This can be attributed to the increase in porosity and agglomeration of nano reinforcement in the composite.
