Effect of Nano TiO₂/Clay on the Erosive Wear Behavior of Basalt-Epoxy Hybrid Composites at Elevated Temperatures

Abstract

Materials added to the matrix help improving operating properties of a composite. In the last few years, nanofiller /polymer composite have been widely investigated because of their outstanding multifunctional properties. In order to improve the erosive wear resistance of composite, an attempt was made to use nanoTiO2 and nanoclay as filler for the basalt reinforced epoxy composite (BE). The impact velocity, filler concentration and temperature are the parameters used for the study. The composites were fabricated using vacuum assisted resin infusion technique (VARI) technique. The fabricated composite specimens were tested by using erosive wear test rig as per ASTM G76 under normal incidence. The result shows that the erosion rate increases with increase in temperature and impact velocity. However, nanoTiO2-filled BE composite exhibits lower erosion rate as compared to Nanoclay filled and unfilled composite. The morphology of eroded surfaces was examined by using scanning electron microscopy (SEM).

Wear Properties of Nanoclay Modified Basalt Fibre Composites Under Dry Adhesive Sliding, Two-body Abrasive and Slurry Pot Erosive

“…This might be due to threebody abrasive wear, where the high content of nanoclay that ploughed out of epoxy matrix has acted as abrasive and slide between the surface of composite and abrading roller, leading to further matrix damage and fibre removal [12]. sand mixture was unable to penetrate efficiently into the surface [17]. However, the wear rate actually increased as nanoclay content increased, which might due to decrease adhesion between nanoclay and epoxy matrix caused by agglomeration [44].…”

“…Basalt fibre has shown excellent mechanical properties, high abrasion resistance and relatively low price [15]. Their mechanical and thermal properties are proven to be better than E-glass fibre, comparable to S-glass fibre and they are cheaper than carbon fibre [17][18][19][20][21].…”

Slurry Pot Erosion Wear of Nanoclay M odified Short Fiber Reinforced Polymer (SFRP) Composites

“…The advances in material sciences has influenced researches to explore the erosive performance of advanced fiber reinforced polymer composite in which fiber and filler exists together as reinforcement to the polymer matrix. Studies by Mahesha et al, Joshi et al, Rao et al, and Ray et al [6], [14], [15] focused on solid particle erosion behavior of these materials with variable factors of erodent concentrations, erodent size, impingement angle, speed, and temperature.…”

“…Therefore, it can be seen that basalt fiber has a very promising future as a natural fiber that can replace synthetic fibers, based on the wear rate obtained. Basalt fiber's ability and behavior to resist erosion wear of epoxy polymer might become one of the key factor in material selection for application under adhesive and abrasive wear [14].…”

“…The applied load has a higher effect on the wear behavior of the developed composites. Mahesha et al [5] studied the erosive wear of epoxy hybrid composites using Basalt and Nano clay/TiO2 as a reinforcing material. The erosion wears increase with an increased in temperature and velocity of impact.…”
