The loss of the mass due to erosive wear by impingement of small solid particles is a critical design consideration while selecting a material for structural applications like bumpers in automobiles, cladding for armour vehicles, pipelines carrying solid particles and material handling systems (Rao et al., 2016). Material for high temperature tribology has been studied by (Wang and Huang, 2017)
With the replacement of metals, alloys with composites, the study of the erosive behaviour of composites under slurry environment is essential (Joshi et al., 2014). The study carried out by(Manoj et al., 2008) showed that the slurry erosive resistance of Fe-TiC composite can be improved by adding TiC in Fe matrix. The influence of erodent characteristics on erosion resistance of titanium was studied by (Lindgren and Perolainen, 2014). The slurry erosive behaviour of metal matrix coatings was studied by (Farahmand et al., 2015). The slurry erosive wear behaviour of SiC ceramic foam/epoxy co-continuous phase composite was studied by (Ren et al., 2015). Slurry erosive behaviour of basalt reinforced low density polyethylene was studied by (Akinci et al., 2011).
Many researchers have studied the slurry erosive wear behaviour of metals, alloys and in the field of composites, metal matrix composites are concentrated. Since nowadays, the polymer matrix composites are replacing the metals, alloys and metal matrix composites owing to various advantages like cost and weight, the study of erosive behaviour of polymer matrix composites under slurry environment is essential (Joshi et al., 2014). Elastomers provide cutting edge advantage over other wear resistant materials in terms of resilience, ease of fabrication, corrosion resistance, toughness, vibration damping capability and so on. Natural rubbers have excellent resistance to erosion and abrasion when hydrocarbon and weathering resistance are not essential. Elastomers find their application in hoses, pipe linings, hose bends, side liners and pump casing (Xie et al., 2015). There are various parameters that affect erosion rate during slurry pot testing like particle velocity, abrasive concentration, particle size and property of material (Levy and Crook, 1991; Rao et al., 2016). There is no literature available on the slurry erosive wear behaviour of polymer matrix composites and especially flexible composites.In this regard, the present study is aimed at studying slurry erosive behaviour of flexible polymer matrix composite and analysing the effect of factors like stacking sequence, rotation speed and sand concentration on the erosive behaviour of the composite.
