“…Pettarin et al [30] reported the wear behavior of high molecular weight high density polyethylene (HMWHDPE)/ MoS 2 composites under dry sliding and abrasive wear conditions. They concluded that, incorporation of MoS 2 to HMW-HDPE improves its sliding and abrasive wear performance with a content of MoS 2 for minimum wear rate around 10 wt.%.…”

Various amounts of short fibers (glass and carbon) and particulate fillers like polytetrafluoroethylene (PTFE), silicon carbide (SiC), and alumina (Al 2 O 3 ) were systematically introduced into the thermoplastic copolyester elastomer (TCE) matrix for reinforcement purpose. The mechanical properties such as storage modulus, loss modulus, and Tan by dynamic mechanical analysis (DMA) and three-body abrasive wear performance on a dry sand rubber wheel abrasion tester have been investigated. For abrasive wear study, the experiments were planned according to 27 orthogonal array by considering three factors and three levels. The complex moduli for TCE hybrid composites were pushed to a higher level relative to the TCE filled PTFE composite. At lower temperatures (in the glassy region), the storage modulus increases with increase in wt.% of reinforcement (fiber + fillers) and the value is maximum for the composite with 40 wt.% reinforcement. The loss modulus and damping peaks were also found to be higher by the incorporation of SiC and Al 2 O 3 microfillers. The routine abrasive wear test results indicated that TCE filled PTFE composite exhibited better abrasion resistance. Improvements in the abrasion resistance, however, have not been achieved by short-fiber and particlaute filler reinforcements. From the Taguchi's experimental findings, optimal combination of control factors were obtained for minimum wear volume and also predictive correlations were proposed. Further, the worn surface morphology of the samples was discussed.

“…More particularly, synthesis, mechanical and tribological behavior of novel lignin-ultra high molecular weight polyethylene (UHMWPE) composites is reported in this paper. It is also well known that the addition of particulates such as kaolin [26], MoS 2 [27], and Ti 3 SiC 2 [28] can tailor the tribological behavior of UHMWPE.…”

Abstract:In this paper, we report the synthesis and characterization of ultra-high molecular weight polyethylene (UHMWPE)-lignin composites. During this study four different compositions, namely UHMWPE, UHMWPE-13 wt. % lignin, UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % lignin were fabricated by hot pressing. Detailed microstructural studies by scanning electron microscopy (SEM) showed that UHMWPE and UHMWPE-13 wt. % lignin had a uniform microstructure, whereas UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % lignin samples were riddled with pores. UHMWPE and UHMWPE-13% lignin showed comparable flexural strengths of~32.2 MPa and 32.4 MPa, respectively. However, the flexural strength dropped drastically in UHMWPE-25 wt. % lignin and UHMWPE-42.5 wt. % samples to~13 MPa and~8 MPa, respectively. The tribology of UHMWPE-lignin composites is governed by the tribofilm formation. All the compositions showed similar µ mean values and the specific wear rates (WR) decreased gradually as the concentration of lignin in UHMWPE was increased.

“…Polymers filled with solid lubricant (SL) have been extensively studied because of the increasing industrial and material applications. Several researchers [4][5][6][7][8][9][10][11][12][13][14] have revealed variation in properties of polymer composites filled with solid lubricants such as graphite, molybdenum disulphide (MoS 2 ), and polytetrafluoroethylene (PTFE).…”

“…Pettarin et al [4] have assessed the effect of the addition of commercial molybdenum disulphide (MoS 2 ) on the tribological behavior of high molecular weight high density polyethylene and observed that addition of 10 wt% of solid lubricant (MoS 2 ) increased the wear resistance under both sliding and abrasive wear conditions, but with a high cost in its mechanical behaviour. A comprehensive comparative study of four different internal lubricants (PTFE, graphite, MoS 2 , and SnS 2 ) on sliding wear of epoxy compounds was reported by Jacobs et al [5].…”

The present work reveals the effect of the addition of commercial MoS 2 (10 wt%) particles on mechanical and two-body abrasive wear behavior of epoxy with/without glass fiber mat reinforcement. The composites were fabricated using casting and simple hand lay-up techniques followed by compression molding. The mechanical properties such as density, hardness, tensile, and flexural properties were determined as per ASTM standards. The abrasive wear testing was carried out using pin-on-disc wear tester for different loads and abrading distances at constant speed of 1 m/s. A significant reduction in wear loss and specific wear rate was noticed after the incorporation of MoS 2 filler allowing less wear of matrix during abrasion which in turn facilitated lower fiber damage. However the incorporation of MoS 2 particles had a detrimental effect on most of the mechanical properties of the composites. The worn surface features were investigated through scanning electron microscopy (SEM) in order to investigate the wear mechanisms.
