Erosive wear characteristics of E‐glass fiber reinforced silica fume and zinc oxide‐filled epoxy resin composites

Abstract

In the present study, the effect of addition of silica fume, also known as microsilica, and zinc oxide fillers on the erosive wear behavior of bidirectional E‐glass fiber‐based epoxy resin composites has been investigated. The amount of silica fume and zinc oxide fillers in the composites was changed in the interval from 0 to 16 wt.%. The erosive wear of the composites has been evaluated at different impingement angles from 20° to 90° and at four different impact velocities of 70, 100, 150, and 200 m/s. The erodent particles used were silicon carbide (SiC) with the average particle sizes of 72 μm, 175 μm, and 348 μm, respectively. The results show that the erosion rate increases with increasing impingement angle, impact velocity, exposure time, and erodent particle size in all the composites. By comparing the two types of fillers, the composites filled with silica fume showed better erosion resistance than those of zinc oxide‐filled composites at the same filler loading. The composite filled with 16 wt.% silica fume presented the best erosion resistant while the highest erosion rate was obtained at the composite filled with 16 wt.% zinc oxide. The morphology of eroded surfaces was examined by using scanning electron microscopy, and possible erosion mechanisms were discussed.

“…The impingement angle, impact velocity, and erodent size are the most studied factors that significantly influence erosion behavior. It was well documented in the literature that erosion wear remains highest for ductile and brittle materials at low (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30) and high (90 ) impingement angles, respectively. [27] In comparison, erosion wear is found to increase with an increase in impact velocity and erodent size.…”

[27] In comparison, erosion wear is found to increase with an increase in impact velocity and erodent size. Therefore, in the current study, a combination of control factors for minimizing the erosion wear was optimized using the Taguchi approach.…”

“…The erosion wear performance of glass fiber reinforced epoxy composites filled with micro silica and zinc oxide fillers was investigated by Öztürk et al. [27] Erosive wear was evaluated as a function of impingement angle, impact velocity, and SiC erodent. The authors concluded that the erosion wear rate increased with increased exposure time, impact velocity, impingement angle, and erodent size and remained lowest for micro silica filled composites.…”

Comparative Analysis of Erosive Wear Behaviour of Epoxy, Polyester and Vinyl Esters Based Thermosetting Polymer Composites for Human Prosthetic Applications Using Taguchi Design

“…Several studies have been reported in the past for the investigation of erosive wear of polymer composite containing different types of fiber and fillers [ 37 ]. For instance, glass fiber reinforced polymer composite filled with micro silica and zinc oxide was fabricated via vacuum-assisted method and investigated for erosive wear behavior at a different impingent angle ranging from 20° to 90° [ 38 ]. It was reported that silica fumes enhanced the composite’s erosive wear resistance, while zinc oxide promoted erosive wear.…”

“…The strength of the material composites depends upon the atomic and molecular levels ranging at the nanoscale. The nanoscale particles for material ranges from 1 to 100nm, at the nano range the material possessed better features [5] . In organic metals and metal type oxide nano particles are utilized in many commercial uses as they have shown better for Electrical, Thermal, agentic, unique surface and optical features.…”
