Mechanical and abrasive wear behavior of carbon fabric reinforced epoxy composite with and without fly ash cenospheres

Abstract

Carbon fabric reinforced epoxy and carbon fabric reinforced epoxy containing different weight fraction of silane-treated fly ash cenospheres filled composites were cast, sectioned, and subjected to three-body abrasive wear tests for evaluating the abrasive wear behavior. Mechanical characterization was done and a comparison was made between the different samples. Abrasive wear tests were performed on a rubber wheel abrasion tester under different loads, abrading distances using quartz and silica sand as abrasives. The results showed that both unfilled carbon fabric reinforced epoxy and fly ash cenospheres filled carbon fabric reinforced epoxy composites exhibit differing magnitudes of wear volume loss, it being highest for unfilled carbon fabric reinforced epoxy composite. The data trends point to the fact that the wear volume and specific wear rate decreases with increasing fly ash cenospheres loading in carbon fabric reinforced epoxy composites. It was found that silane-treated fly ash cenospheres could effectively reduce the wear rate especially under silica sand as abrasives. To explain these differences, the worn surfaces were examined using scanning electron microscope and the features thus observed were correlated with the selected mechanical properties.

Effect of blast furnace slag content on mechanical and slurry abrasion behavior of needle‐punched nonwoven fabric reinforced epoxy composites

“…Gradually, wear tracks formed and fibers getting exposed to the abrasive environment. Similar observations were reported with the addition of fly ash cenosphere particles in carbon fabric composite by Arivalagan et al [8] and with SiC filler in glass fabric composites by Raju et al [32] Entrapment of wear debris between the rubber wheel and composite surface reduces the wear rate.…”

“…Needle-punched nonwoven fabrics emerged as an excellent reinforcing material for the high-performance composites due to its resin absorbing quality, potential against delamination problems, and cost effectiveness. Mechanical and abrasive wear behavior of fly ash cenospheres filled carbon fabric epoxy composites analyzed by Arivalagan et al [8] The abrasion resistance and the mechanical properties were improved significantly with the inclusion of filler. Among all fibers, polyester are widely used due to many advantages which include good mechanical strength, inexpensiveness, good abrasion resistance, very low moisture absorbency, high glass transition and melting temperature, high heat resistance, resistance to hazardous chemicals, biocompatibility, and largely available in different cross-sectional shapes.…”

“…They observed that wear debris increased with increase in temperature and factor normal load highly affect the wear rate of the composite. Jain et al [18] investigate the effect of multi-walled carbon nano tube (MWCNT) with variation of 0.5 and 1 wt.% as a filler with glass-epoxy composites. They found that MWCNT filled glass-epoxy composite shows better wear resistance and friction coefficient than unfilled glass-epoxy composites.…”
