“…Several researchers have developed the fillers reinforced epoxy composites. The commonly used fillers in the case of metal composites are B4C [9], graphite [10], SiC [11], TiC [12], Al2O3 [13], Graphene [14], Red mud [15], TiO2 [16], Si3N4 [17], ZrO2 [18], mica Brazilian Journal of Development, Curitiba, v.10, n.5, p. 01-13, 2024 [19], AlB2 [20] and WC [21]. These particles act as a filler in the case of polymer composites to increase the wear resistance.…”

In this research, agriculture residues as reinforcement and filler were utilized for an epoxy-based matrix material. Glass fibre was incorporated in this composite throughout the production process in addition to the kenaf fibre. Rice husk ash filler in the matrix was maintained at 10 wt %, while the kenaf/glass hybrid fibre varied from 0 to 40%. Compression moulding was used to create the hybrid to study its mechanical attributes, which includes tensile strength, flexural strength, and impact strength. The results showed that due to the wettability of the given hybrid matrix, it exhibits superior mechanical characteristics. For 30% hybrid fibre and 10% filler material, the mechanical properties like tensile strength, flexural strength, and impact strength were raised by 41.26%, 14.42%, and 63.15%, respectively.

The influence of adding B4C particulates with a 40 and 90 µm sizes on the compressive strength, tensile strength and impact toughness of the A356 alloy is being studied. In the Al alloy matrix, 40 and 90 µm -sized micro B4C particulates are employed as reinforcements. In the A356 alloy, composites are created utilizing the liquid melt process in increments of 3 and 6 weight percent. Using an energy dispersive spectroscope (EDS) and a scanning electron microscope (SEM), samples are examined for microstructural characterization. According to ASTM standards, mechanical characteristics including tensile, hardness, compression, and toughness are assessed. The consistent distribution of B4C particles in the A356 alloy is seen in SEM micrographs, and this is supported by EDS analysis. Additionally, the inclusion of B4C reinforcement improves the compression and impact strength of the base matrix A356 alloy, which is especially noticeable in the case of reinforced composites that are 6 wt. % of 40 µm B4C in size.

The effect of nano-sized B4C particulates on the Zn85-Sn15 alloy has been investigated. Composites reinforced with B4C of (0%, 2%, 4% and 6%, by weight) are manufactured by two step stir casting. Microstructural studies carried out by SEM, EDS, and XRD and mechanical testing like tensile, hardness, and impact were performed on cast samples. The criteria for determining strength and fractography are met. EDS analysis confirms the homogeneous distribution of B4C particles in the Zn-Sn matrix seen in SEM micrographs. XRD examination revealed the B4C phases in the Zn-Sn alloy matrix as well. When B4C reinforcement is added to the basic matrix alloy, it improves its hardness and tensile strength with slight decrease in the ductility and impact strength. Further, tensile and impact fractured surfaces were studied to know the different fracture mechanisms.
