Abstract
AbstractPolymeric composites are widely used for structural, aerospace, and automobile sectors due to their good combination of high specific strength and specific modulus. These two main characteristics make these materials attractive, compared to conventional materials like metal or alloy ones. Some of their typical benefits include easy processing, corrosion resistance, low friction, and damping of noise and vibrations. Wear behavior of Polytetrafluoroethylenes (PTFE) and its composites including glass-filled composites and carbon-filled composites are investigated using a pin-on-disc configuration. A plan of experiments in terms of Taguchi technique is carried out to acquire data in controlled way. An orthogonal array (L9) and the analysis of variance are employed to investigate the influence of process parameters on the wear of these composites. Volume loss increased with abrasive size, load, and distance. Furthermore, specific wear rate decreased with increasing grit size, load, sliding distance, wh...

Polymers and their composites are emerging as viable alternative products to metal or alloys in many advanced engineering applications
The abrasive wear behavior of short carbon/glass fiber reinforced with PEEK/polyphenylene sulfide (PPS) polymers showed that the wear rate was sensitive to the orientation of the fiber axis with respect to the sliding direction (Harsha & Tewari, 2003; Lhymn, Tempelmeyer, & Davis, 1985; Mishra & Acharya, 2010)
The results showed that the highest specific wear rate was for glass fabric reinforced vinyl ester composite with a value of 10.89 × 10−11 m3/N m and the lowest wear rate was for carbon fabric reinforced vinyl ester composite with a value of 4.02 × 10−11 m3/N m
Summary
Polymers and their composites are emerging as viable alternative products to metal or alloys in many advanced engineering applications. For abrasive wear of composites, microscale wear, short fiber (Cirino, 1988; Lhymn et al, 1985; Mishra & Acharya, 2010; Shipway & Ngao, 2003); influence of fiber orientation (Chand & Dwivedi, 2007a; Dwivedi & Chand, 2009; Harsha & Tewari, 2002); effects of fillers like carbon and glass fiber (Bijwe et al, 1989; Friedrich 1993; Suresha et al, 2007); Vinyl ester, UHMWPE, and Polyamide 6G (Liu et al, 1999; Suresha & Kumar, 2009; Ravi Kumar et al, 2009; Yousif et al, 2010); cotton fiber, anisotropic bamboo, and short glass fiber (Chand et al, 2007; Chand & Dwivedi, 2007b; Chand et al, 2000; Eleiche & Amin, 1986); bamboo, SiO2, glass fabric, and particulate glass fillers (Chand et al, 2000; Raju et al, 2012; Tong et al, 1995); and tribofilm formation (Bahadur & Sunkara, 2005; Bahadur et al, 1997; Patnaik et al, 2010; Vande Voort & Bahadur, 1995) are studied experimentally. The Taguchi L9 (33) method and ANOVA are adopted to identify the effect of process parameters on the wear of tested materials
