“…Since researchers' primary aim was improving matrix fiber bonding by doing various chemical modification techniques [13,14], various chemical treatments are used to treat natural fibers in order to improve their interfacial contact with the matrix [15,16]. Furthermore, adding ceramic fillers to resin improves the mechanical characteristics of composite materials, resulting in increased efficiency and cost savings [1,[17][18][19][20]. When compared to composites without silica, mudar/snake grass/polyester composites with silica had 1.5 and 1.08 times the tensile strength and modulus, respectively [18,21].…”

The impact of SiO2 and B4C on mechanical and morphological studies of Sansevieria trifasciata fiber (STF) reinforced in polyester composites is investigated in this study. STF fibers are reinforced with polyester composites with the addition ceramic fillers such as SiO2 and B4C in various weight fractions to improve tensile, flexural, and impact characteristics. The morphological properties are studied with the help of scanning electron microscopy (SEM). The improved mechanical properties were tensile strength (44.92 MPa), flexural strength (103.58 MPa), and impact strength (27.4 kJ/m2) obtained for 20 wt.% STF fiber and 15 wt.% SiO2 reinforcement with the polyester matrix. The mechanical characteristics of the composites were significantly influenced by increasing SiO2 up to 15 wt.%.

“…The abundance of raw materials has a lot of advantages such as: easy processing, simple manufacturing, relatively low cost and easy of use etc. Using the ceramics is increased with reasons of hardness, heat resistance [2]. Ceramics are typically produced by forming ceramic particles in to a desired shape and applying heating a process known as firing.…”

“…The dielectric ceramics Pb (Zr,Ti)O3, abbreviated (PZT) are very sensitive oxides to insert ion or substitute ion at site A(and/or) site B, because of their simple perovskite ABO3 structure. The purpose of doping is often related to the improvement of ceramic properties for their industrial applications (sensors, actuators and resonators) [2]. Lead-containing ferroelectric materials such as Pb (Zr, Ti) O3(PZT) and PZT-based [6,7].…”

“…However, the fracture toughness of alumina ceramics is low, as a result, the material becomes brittle and thus its application reduces. Numerous research has been carried out to improve tribological behavior in conformal contact by incorporation of oxides like CuO, Y 2 O 3, ZrO 2, MgO, TiO 2 , Nb 2 O 3 8‐12 and nonoxides like SiC, TiN, TiB 2 ,CNT 13 etc as a secondary phase in alumina matrix. Valefi et al 14 investigated the effect of CuO addition into yttria stabilized tetragonal zirconia polycrystalline (Y‐TZP) ceramics sliding against alumina ball in conformal contact.…”

The well-known alumina ceramics have extensive structural application due to its outstanding physico-mechanical properties like hardness, wear resistance, good thermal conductivity, and thermal and chemical stability even at high temperature. 1 Its typical application includes in various engineering fields such as laser tubes, cutting tools, wear pads, high temperature electrical insulators, electronic substrates, automobiles, especially in unlubricated engines, aerospace, and even in biomaterials. 2-7 However, the fracture toughness of alumina ceramics is low, as a result, the material becomes brittle and thus its application reduces. Numerous research has been carried out to improve tribological behavior in conformal contact by incorporation of oxides like CuO, Y 2 O 3, ZrO 2, MgO, TiO 2 , Nb 2 O 3 8-12 and nonoxides like SiC, TiN, TiB 2 ,CNT 13 etc as a secondary phase in alumina matrix. Valefi et al 14 investigated the effect of CuO addition into yttria stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramics sliding against alumina ball in conformal contact. They reported that the coefficient of friction (COF) reduces to 0.35 with a low wear rate (<10 −6 m 3 /N m) due to accumulation of soft copper oxide layer which causes shifting of the wear mechanism from brittle to ductile and increases wear resistance. The effect of different lubricating additives like TiC, CNT, CaF 2 etc to improve tribological attributes of alumina and alumina-zirconia composite up to a certain level of addition and range of temperature by reinforcement in the matrix was also reported by several researchers. 15-18 Countersurface plays an essential role on COF Kerkwijk et al 10 have reported that COF changes from 0.65 to 0.43 when Al 2 O 3 ball is replaced by Y-TZP ball as a counter surface on 5 wt.% CuO added alumina sintered.
