Wear analysis of waste marble dust-filled polymer composites with an integrated approach based on design of experiments and neural computation

Abstract

Waste marble dust is a solid waste generated during the cutting and polishing of marble pieces in construction sites and also in marble processing industries. This paper reports on the utilization of this waste as a filler material in particulate-filled polymer composite. Polyester-based composites are prepared with different weight proportions of waste marble dust and the dry sliding wear behavior of these composites is studied. Wear trials are conducted using a pin-on-disc test apparatus based on the Taguchi’s L25 orthogonal array as per ASTM G 99-05. The effects of different parameters on the specific wear rate of the composites are studied and an optimum combination of parameters is obtained for the least wear rate. Based on the experimental data, a prediction model using the artificial neural network is used to predict the specific wear rate of the composites at a wider range of operating parameters, within and beyond the test region. The morphologies of the worn surfaces are studied by a scanning electron microscope to ascertain the wear mechanism of the composites at different conditions. This work thus opens up a new avenue for the value added utilization of a waste like marble dust in tribological applications.

Utilization of Waste Marble Dust in Poly(Lactic Acid)-Based Biocomposites: Mechanical, Thermal and Wear Properties

“…Analysis of these results leads to the conclusion that combination of factors A4 (20 wt% MD), B1 (400 m sliding distance), C1 (1 m/s sliding velocity) and D1 (10 N normal load) gives minimum volumetric wear. Similar observations have been reported by various researchers in regard to the effect of MD as filler on the wear performance of polymer composites [45,46]. Authors claimed that wear resistance was remained highest with the combination of lower sliding distance, sliding velocity, normal load with higher MD filled polymer composites.…”

A critical review on tribological properties, thermal behavior, and different applications of industrial waste reinforcement for composites

“…40 The reason reported by authors for such wear mechanism is more brittleness of the composite at higher MD content with no plastic deformation and where only wear debris is found. 40 Sharma et al studied the effect of MD reinforcement (0-30 wt%) on needle-punched nonwoven epoxy composites by examining the erosion wear rate mechanism. Their study concluded that the addition of MD filler has provided an improved erosion wear resistance.…”

“…At higher reinforcement of MD, short and continuous wear tracks are visible while low content of MD results in micro-fracture and plastic deformation in composites (see Figure 8). 40 The reason reported by authors for such wear mechanism is more brittleness of the composite at higher MD content with no plastic deformation and where only wear debris is found. 40 Sharma et al studied the effect of MD reinforcement (0-30 wt%) on needle-punched nonwoven epoxy composites by examining the erosion wear rate mechanism.…”

Design of a composition based on polyethylene and marble microparticles that decomposes under the effect of ultraviolet radiation

“…Work [11] designed new polymeric composites with a filler in the form of waste of marble dustsolid waste. This waste forms when cutting and polishing marble pieces at construction sites, as well as at marble processing enterprises.…”

“…It is shown that the coefficient of thermal conductivity of the composites increases with an increase in filler content. Similar to works [9][10][11], the impact of natural factors on the stability of the composite was not tackled.…”
