Wear characteristics of glass‐polyester‐based hybrid composites: A parametric analysis using response surface method and fuzzy logic

Abstract

Marble dust generated during processing of the marble producing rocks is a major solid waste with a detrimental impact on environment. Analysis shows that this waste has constituents having compounds like SiO2, Al2O3, Fe2O3, CaO, MgO, etc., in different proportions. This paper explores on the possible use of waste marble dust as secondary filler in glass‐polyester composites and reports on its dry sliding wear characteristics. Such hybrid composites with unsaturated polyester as the matrix are fabricated by keeping the woven glass fibre loading fixed and by varying the weight fraction of the particulate filler, that is, marble dust through a simple hand layup route. Dry sliding wear trials are conducted under different test conditions as per ASTM G 99‐05 following the L30 model of response surface method (RSM). A parametric appraisal of the wear process is made using RSM and the significant control factors and their interactions influencing the specific wear rates are identified. Scanning electron microscopy of the worn composite surfaces is done to ascertain the wear mechanism. It is found that the presence of marble dust improves the wear resistance of unfilled glass‐polyester composites substantially. Further, prediction of wear rate of the composites for a wide range of filler content and sliding velocities is conducted using RSM and another prediction model based on fuzzy logic and the outcomes are compared.

Analysis and characterization of interlaminar tack for different prepreg materials during automated fiber placement

“…Therefore, the number of samples has to be reduced. As is well known, the response surface method [ 30 ] is an efficient tool for designing a process that operates effectively over a variety of conditions. In this study, three levels are selected for each process parameter.…”

Tribological Performance of Composites Reinforced with the Agricultural, Industrial and Post-Consumer Wastes: A Review

“…Composites with the highest marble dust content exhibited the lowest erosion rate regardless of the applied impingement angle and impact velocity. In their two literature reports, Nayak et al determined the sliding wear behavior of hybrid composites made of unsaturated polyester resin, E-glass fiber mat (10-layers, 40 wt %) and waste marble dust (0–16 wt %) [ 99 , 100 ]. The authors demonstrated that the highest sliding wear resistance was observed for the composites with maximal waste marble dust weight percentage (16 wt %).…”

Design and multi‐objective optimization of the bumper beams prepared in long glass fiber‐reinforced polypropylene

“…Based on the above results of the optimized Latin Hypercube test, the Design‐Expert software is used to select the response surface model (RSM) for the proxy model to optimize the crashworthiness of the composites beams with variable thickness. [ 32 ] Since the RSM has good robustness and a limited number of optimization parameters, the RSM is selected for polynomial fitting as Formula (). [ 7 ] where y is the true response value, f is the approximate response polynomial, and ε is the response error.…”
