Optimization of Abrasive Wear Parameters of Halloysite Nanotubes Reinforced Silk/Basalt Hybrid Epoxy Composites using Taguchi Approach

Abstract

The demand for environmentally friendly and sustainable materials for nonstructural and structural applications grows by the day. Polymeric composites reinforced with fillers and fibres are considered to have increased strength and desirable wear resistance. Abrasive wear of industrial and agricultural based components are currently one of the most serious issue. Therefore, the current research reports on the influence of Halloysite-Nanotubes (HNTs) loading on the three body abrasive behavior of bidirectional silk fibre (SF) and basalt fibre (BF) reinforced epoxy (Ep) composites. Rubber wheel with dry sand abrasion testing in accordance with ASTM G65-16e1 was performed with four control parameters such as filler content, load, abrading distance and silica sand size. The tests were planned as per orthogonal array of Taguchi (L27). Significant impact of control factors were identified using ANOVA (Analysis of variance). The results demonstrated that adding HNTs to SF-BF/Ep nanocomposites significantly improved the wear resistance and the combination of A2, B1, C3 and D1 control factors yields the lower specific wear rate (SWR). Findings exhibit that the load and abrading distance were the most significant parameters affecting the abrasive wear of SF-BF/Ep nanocomposites followed by filler content and silica sand size. Microstructural features were observed via scanning-electronmicroscopy (SEM).

“…Four parameters viz abrading distance, amount of filler, applied load, as well as silica sand size at three levels were considered. The results showed that abrading distance was the most influential control factor that affected the wear rate [24]. The Taguchi method establishes single parameter significance.…”

“…According to the findings, it was demonstrated that sliding distance was the most influential factor affecting the wear rate [23]. Darshan, Suresha, and Jamadar [24] studied the effect of parametric wear rate of Hallosyte nanotube reinforced basalt/silk epoxy composite. Four parameters viz abrading distance, amount of filler, applied load, as well as silica sand size at three levels were considered.…”

Mechanical Properties and Analysis of Two-body Abrasive Wear Behaviour of Graphene Modified Carbon/Epoxy Composites Using Taguchi’s Technique

“…The use of epoxy resin as a matrix material is known to significantly enhance the strength (tensile, flexural, and impact) of mono/hybrid composites (e.g., SiC filled carbon/epoxy and Al2O3 filled carbon/epoxy, SiC filled glass/epoxy) parts [6,7]. In PMCs, Although there is a wide range of matrix/binding materials used (Table 1), epoxy resins offer excellent strength which makes them more practical in aerospace, automotive and marine applications [8].…”
