“…Therefore, a large number of factors are included so that non-significant variables can be identified at earliest opportunity. Exhaustive literature review on erosion behaviour of polymer composites reveal that parameters viz., impact velocity, filler content, erodent temperature, impingement angle, stand-off distance and erodent size etc largely influence the erosion rate of polymer composites [8,11,17]. The impact of six such parameters are studied using L 27 (3 13 ) orthogonal design.…”
