“…In the second category, reinforcement particles are embedded in a metal matrix, and the best way to make this type of composite is to use powder metallurgy (13,14). Recently, the use of quasi-crystalline materials as reinforcement particles in aluminum-based composites has received much attention (15,16), because quasicrystalline alloys and composites containing quasicrystalline phase improve some properties due to their complex atomic structure, unique mechanical and tribological properties, and special thermal behavior (17,18) .These properties make them suitable for applications such as surface coatings, reinforcement particles in composites and catalytic applications (4,19,20). Conventional sintering methods such as hot press, high temperature extrusion, hot isostatic press lead to grain growth which affects the properties of the final product.…”

In this study, Al-based composites reinforced with Al59Cu25.5Fe12.5B3 quasicrystal (QC) were prepared by spark plasma sintering (SPS) method. Microstructural and mechanical properties were examined. It is observed that with addition of quasi-crystalline reinforcement the intensity of the quasi-crystalline peak has increased. Also, it is observed that by performing spark plasma sintering, the quasi-crystalline particles maintain their stability. Due to low temperature of the process and the short time of spark plasma sintering, the occurrence of destructive phases within the quasi-crystal has been prevented. based on field emission scanning electron microscopy (FESEM) images, the distribution of quasi-crystalline particles at the sample level has increased. In addition, the mechanical properties are improved by increasing the quasi-crystalline particles. Therefore, the sample with 15 vol.% of quasi-crystal has better results than other samples in improving microstructural and mechanical properties and it can be considered as an optimal sample with suitable practical properties.

“…In the first category, hard particles (ceramic: Al 2 O 3 , B 4 C, SiC, CNTs, TiB 2 , etc., and intermetallic: AlFe 3 , AlFeCu, etc.) are embedded in the aluminum matrix as reinforcement to achieve extraordinary strength [6][7][8][9][10][11][12][13][14][15][16][17]. However, with the increase in reinforcement volume fraction, the ductility of the composites significantly decreases due to the brittle nature of reinforcement and weak interfacial bonding be-tween reinforcement and matrix [18][19][20].…”

In this study, Al matrix composites (AMCs) reinforced with Al/Cu core-shell particles were synthesized by hot pressing. The Al/Cu particulate reinforcements were pre-synthesized by galvanic replacement. The effect of the volume fraction of reinforcement on the microstructure and mechanical behavior of the composites was investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), micro-hardness and compression tests. The strength of the composite becomes 2.25 times the matrix by using 20 vol.% core-shell reinforcements containing only 6 vol.% Cu. Further, with increasing volume fraction of Al/Cu reinforcement, the degree of in-situ transformation of Cu into intermetallic also increases. Consequently, a specially tailored microstructure can be obtained by controlling the volume fraction of the reinforcement and its interfacial reaction with the matrix, which can improve the mechanical strength of composites without considerably compromising on fracture strain. The findings of this work provide stronger implications for the industry to fabricate viable engineering structures.

“…Because of its unique nature and good biocompatibility, it could be employed to substitute commonly used chemical fibers such as carbon and glass fibers [1][2][3] . Natural fiber reinforced with different matrices have been explored in recent studies moderately, in that about 15-20 percent is being employed in the vehicle industry and even more exclusively used in construction industries due to all applications [4][5][6] . In the researcher's point of view, natural fibers are generally divided into two categories: plant-based and animal-based.…”

In this work, various proportionate (0%, 1%, 3% 5% & 7%) of titanium di-oxide nano-filler was utilized as particulate matter along with the sisal/jute fiber reinforcement, in the view to increase the physical properties of the composite materials. Beside, as matrix material the mixture of Epoxy (E) and Polyurethane (PE) was chosen with the proportionate of 70 and 30 wt.% respectively, in order to extract the specific qualities of both the matrices to achieve the interpenetrating polymer networks (IPNs). Moreover, to exactly find out the thermo-mechanical characteristics of the sisal/jute fiber reinforced IPN composites, tests like thermo-gravimetric analysis (TGA), tensile, flexural, Impact, short beam strength and water absorption tests were carried out as per standards. It was found that, incorporation of 5% of TiO 2 , increases the mechanical properties such as tensile, flexural, impact and short beam strength. Similarly, incorporation of TiO 2 into IPN matrix enhances the thermal stability and water absorption resistance. All the obtained values of various filler weight % of TiO 2 were compared with each other against with and without particulate incorporated IPN laminate in the purpose of using the same in construction industries.
