Analysis of wear behavior and shear properties of nano – ZnO2/jute fiber/epoxy composites by Hand layup technique

Abstract

Nano-ZnO2 was added to a jute fiber/epoxy composite whether it affected wear metrics and compressive strength. A silane-coupling agent with an amin-terminated end was used to functionalize the surface of ZnO2 nanoparticles. The modified ZnO2 was characterized employing FTIR spectroscopy and TGA. Using the hand layup method, the multiscale composites were created by distributing different amounts of nanoparticles (0.5, 1, 3, also 5 wt%) in matrix. The 3weight%ZnO2-filled compound has the finest characteristics out of all of these specimens. Adding ZnO2 to the composites caused in a 43 % increase in Compressive property in the short-beam shear test. Adding 3 wt. %ZnO lowered wear rate by 80 % and COF by 48 %. Wear and fracture mechanisms were studied. According to the discoveries of this study, M - ZnO2 is a promising alternative to be employed as a nanofiller in fiber-strengthened polymeric matrix. An epoxy/jute composite was supplemented with nano-ZnO2 to examine the effects on wear metrics and interlaminar shearing strength during dry sliding, according to the study's findings. A silane-coupling agent with an amin-terminated end was used to functionalize the surface of ZnO2 nanoparticles. The modified ZnO2 was characterized using Fourier-transform infrared spectroscopy and thermogravimetric studies. Hand layup was used to disperse different quantities of nanoparticles (0.5, 1, 3, also 5 wt%) in the matrix to create the multiscale composites. The 3 wt%ZnO2-filled composite has the finest characteristics out of all of these specimens.
