Abstract
The present work is focused on studying the wear behavior of marble filled hybrid NPNJE composites in slurry condition. A set of composites consisting of marble powder in different weight percentage (0 to 30 wt% in step of 10) are prepared using VARTM technique. Maximum erosion occurs at 45° and 75° for unfilled and marble filled composites respectively. The addition of marble powder has changed the nature of composite from ductile to semi-brittle as witnessed from the surface studies. The Taguchi analysis (L16 orthogonal array) is also employed to achieve a set of control factors that determines the minimum erosion rate, also corroborated through validation experiment. The best possible combination for minimum erosion rate is A1B2C1D2 as observed from the main effect plot. Factor A is observed to have more contribution in the analysis of slurry erosion behavior of NPNJE composites followed by factor B and C. The unfilled and marble filled NPNJE composite are characterized using FTIR to identify the functional groups and its constituents. Oka erosion model is employed to validate the dependency of the impingement angle for the obtained erosion result. Micro-cracking, fiber exposure and breakage, fiber-matrix debonding are dominant erosion mechanism as observed from surface studies.
