The effect of different fillers, loads, and sliding distance on adhesive wear in woven e-glass fabric composites

Abstract

In this study, adhesive wear of woven E-Glass fabric reinforced composites filled with aramid, B4C and mica particles at 0.5% wt. and 1.5% wt. ratios were carried out under dry sliding conditions. The effects of filler type, applied loads (5, 10 and 15 N) and sliding distances (250, 500 and 750 m) on the tribological behavior of the composites were investigated on the pin-on-disc device. As a result of the studies, it was determined that the friction coefficient in aramid reinforced composites was lower than the other reinforced composites. In wear volume due to wear, it was observed that the aramid wear volume was less. In addition, Wear volume increased with increasing load for all particle reinforcements. But, the highest wear volume occurred in the neat wear sample at 15 N load conditions. For the wear rate and wear volume, the fillers have shown improvement up to 1.5% wt. in the composite. 1.5% wt. aramid-filled glass fiber woven composites showed the lowest wear rate: 2.82 × 10−4 mm3/N-m (at 15 N normal load). In addition, in the scanning electron microscope images taken, it was observed that there were breaks in the size of 15.07 µm in the epoxy and 61.11 µm in the fibers. The use of aramid with particle reinforcement rather than fiber is important for wear. In addition, the lowest wear volume was 65% more resistant at 1.5% wt aramid reinforcement and at 15 N load compared to the unreinforced composite in the abrasion tests.

Tribological and mechanical properties of nanofilled glass fiber reinforced composites and analyzing the tribological behavior using artificial neural networks

“…2 Fiberreinforced polymer matrix composites are widely used in industries such as aerospace, automotive, marine, and defense due to their superior strength-to-weight ratios, low density, high corrosion resistance, and excellent tribological properties (low friction coefficient and high wear resistance). [3][4][5] These composites are commonly employed in the production of components such as cams, gears, brakes, wheels, bearing sleeves, seals, rollers, bushings, and clutches. 6 The interfacial bond between the fiber and matrix, fiber alignment, fiber orientation, and interfacial area are important factors in determining the mechanical properties of fiber-reinforced polymer matrix composites (FRPCs).…”

Tribological Performance Study of Low-Friction PEEK Composites under Different Lubrication Conditions

“…Research by Chen et al [13] demonstrated that adding 7 wt% aramid fibers into epoxy resin notably elevates the material's tensile and impact strength, thermal stability, and damping capabilities. Further analysis by Çetkin et al [14] of the tribological characteristics of composites composed of aramid-fiber-filled glass fiber fabric under dry friction conditions revealed that the coefficient of friction decreased as the aramid fibers made adequate contact with the frictional surface. The incorporation of 1.5 wt% aramid fibers into the glass fiber fabric significantly reduced surface deformation of the composites, leading to a 65% improvement in wear resistance properties.…”

Tribological performance study of low-friction PEEK composites under different lubrication conditions

“…Chen et al 13 added 7wt% aramid bers to epoxy resin and showed that it signi cantly improved the tensile strength, impact strength, thermal stability, and damping properties of the material. Çetkin et al 14 researched the tribological behavior of aramid-ber-lled glass ber fabric composites under dry friction conditions. The results showed that the COF decreases when enough aramid bers are in contact with the friction surface.…”
