Abrasive wear and dynamic–mechanical behavior of marble dust filled bagasse fiber reinforced hybrid polymer composites

Abstract

The present study investigated the influence of waste materials on physico‐mechanical, dynamic mechanical, and abrasive wear behavior of polymer composites. The composites were manufactured by varying the waste bagasse fiber (2.5, 5, 7.5, and 10 wt%) in fixed marble dust (15 wt%) filled epoxy resin. The void content of the composite found to decrease, whereas density, impact energy, and flexural strength were found to increase with the increase of waste bagasse fiber loading. The hardness and tensile strength were first increased, and after attaining highest values for 7.5 wt% fiber content, both decreased with another fiber loading. Damping properties such as storage modulus, loss modulus, and damping factor were evaluated utilizing dynamic mechanical analyzer. Results showed that the composites with 10 wt% waste bagasse fiber loading exhibited highest viscoelastic properties. Moreover, the dry sand abrasive wear behavior of fabricated composites was designed to study the impact of fiber loading, sliding distance, and load using the Taguchi method. The analysis reveals that the sliding distance contributes the most toward abrasive wear of the composites, with a contribution of 58.70%. 7.5 wt% waste bagasse fiber, 400 m sliding distance, and 5 N load resulted in a most wear‐resistant combination. Finally, the abraded composite surfaces were examined using scanning electron microscopy to study the possible wear mechanisms.

Effect of Marble Dust on the Mechanical, Morphological, and Wear Performance of Basalt Fibre-Reinforced Epoxy Composites for Structural Applications

“…This is true for randomly oriented short basalt fibre polymer composites. Considering the recent literature, hybrid composites comprised of carbon/basalt/epoxy showed better fracture strain and tensile strain as compared to carbon fibre epoxy composites; however, the tensile properties were reduced [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. These findings suggested that the arrangement of carbon/basalt fibre in the composite plays a crucial role in enhancing composites’ strength [ 32 ].…”

“…At a fixed percentage of waste marble dust (15 wt. %), changing the bagasse fibre weightage to 7.5% improved the mechanical and physical properties of composites [ 31 ]. Not only the mechanical properties but also the wear performance, thermal characteristics, and fire retardancy of the composite were found to be enhanced by the inclusion of marble dust in fibre polymer composites [ 1 , 20 , 28 ].…”

Effect of erosive parameters on solid particle erosion of cotton fiber–based nonwoven mat/wooden dust reinforced hybrid polymer composites

“…11 In this regard, natural fibers, that is, hemp, jute, banana, cotton, sisal, etc., have been successfully utilized as reinforcement by various researchers and scientists. 12,13 Cotton fiber is also a natural type of fiber which is used in textile industries for centuries. Dry weather harvested cotton fiber cultivated in the northern and southern hemispheres from the decades.…”

Effects of boron nitride and carbon nanotube on damping properties, thermal conductivity and compression stress relaxation behavior of BIIR

“…Rubbers usually have low thermal conductivity about 0.10-0.23 W/m K. [5][6][7] Thermally conductive fillers such as boron nitride (BN) and carbon nanotube (CNT) are added into rubbers to prepare thermally conductive rubbers. [8][9][10] Liu et al found that the thermal conductivity of silicone rubber increased by 30% after the addition of 14% BN nanosheet.…”

“…[14] The hollow glass microsphere/ nitride particle ratio and filler surface modification of significantly affected the thermal conductivity, dielectric constant and loss of low-density polyethylene. [15] Rubbers with wide damping temperature range and high damping factor (tan δ value) are an important development direction, [4,16,17] requiring a tan δ value over 0.3 in the temperature range of 60-80 C. [18,19] The damping factor of most rubbers is relatively low, and their effective damping temperature range is 20-40 C. [7,20] The damping properties of most rubbers cannot meet high requirements of applications. [21,22] Chen et al prepared chlorinated butyl rubber (CIIR)/terpene resin/carbon black damping material.…”
