Influence of ZrO₂ Incorporation on Sisal Fiber Reinforced Unsaturated Polyester Composites

Abstract

Sisal fiber along with ZrO2 particles dispersed unsaturated polyester (UP) composites were fabricated by compression molding technique. The filler contents were varied from 5 to 45 wt% with a gradual increase of 10%. The structural investigation was done using Scanning electron microscopy, X‐ray diffraction, and Fourier transform infrared spectroscopy. Mechanical testing was performed through microhardness tester, tensile, flexural, and Izod impact test. The optimum mechanical properties were obtained at 35 wt% of filler incorporation within UP matrix followed by a slight deterioration at 45 wt%. Fractographic images of the composites display the phenomena of fiber pull‐out, debonding and breakage. The water absorption test was performed both at room temperature and boiling water temperature conditions. The thermal insulation measurement was performed by Kawabata method. POLYM.

Fiber-Reinforced Polymer Composites: Manufacturing, Properties, and Applications

“…It offers short cycle time, a high degree of productivity, and automation with dimensional stability, hence it finds diverse applications in the automobile industry [144,145,146]. Dispersion of 35% filler elements containing sisal fiber and zirconium dioxide (ZrO 2 ) particles in the matrix of unsaturated polyester (UP) was obtained by the compression molding technique, which displayed optimum mechanical properties when tested under SEM, X-ray diffraction, and Fourier transform infrared spectrometer (FTIR) [147]. Jute fiber-reinforced epoxy polymer matrix-based composite has been fabricated by using hand lay-up followed by the compression molding technique at s curing temperature ranging from 80 °C to 130 °C.…”

Synthesis and characterization of Sr-doped HAp-incorporated polyether ether ketone composite

“…The enhancement in the microhardness is probably due to the dominant role of increased crystallinity. 14 Another reason of improvement the microhardness may be due to decreased in chain movement with incorporation of dispersion phase. This increment is directly related to the enhancement in the content of the dispersing phase within the PEEK matrix.…”

“…The crystallinity percentage from the XRD patterns was calculated as per the standard equation considering the crystalline peak (2θ = 18.36°) of PEEK matrix. 13,14 where I crystalline = intensity of the crystalline portion of the polymeric matrix corresponding to the 2θ value.…”

Enhancement of surface insulation properties of alumina/epoxy composites through ZrO2 film sprayed by plasma atomization

“…[21] As a Group IVB metal oxide film, zirconium dioxide film has excellent properties of well thermal and mechanical stability, nice resistance to high-temperature corrosion and hightemperature oxidation, and a high degree of binding to organic matter. [22][23][24][25] Xiong et al used atmospheric pressure chemical vapor deposition to successfully prepare zirconia coatings on C/C-SiC and C/C-ZrC substrates, and found the coating has a higher degree of binding to organics. [26] Su et al used atmospheric pressure plasma jet technology to prepare tetragonal ZrO 2 particles and characterized their characteristics, indicating that the plasma jet system has excellent potential for ZrO 2 synthesis.…”
