Properties of Jute Fibers Reinforced Friction Materials

Abstract

Jute fibers reinforced friction materials were prepared by mold and heat treatment. The friction coefficients of 3wt.%,9wt.% and 12wt.% jute fibers reinforced friction materials were bigger than that of the materials without jute fibers in the heating condition. The friction coefficient of 6 wt.% jute fibers reinforced friction materials was bigger than that of the materials without jute fibers below 250°C. The friction coefficient of jute fibers reinforced friction materials deceased with the temperature decrease in the cooling condition. The friction coefficient of the materials with free-jute fibers raised from 350-250°C and reduced at the temperature lower than 250°C.Wear rates of the friction materials raised with temperature rise for jute fibers carbonization led to the matrix became loose. With jute fibers content rise worn surface of the reinforced materials became from smooth to rough. There were pits, grooves, abrasive particles, pulled out fibers and wear debris on the worn surfaces. Abrasive wear was the main wear mechanism.

Friction and wear properties of dumbbell‐shaped jute fiber‐reinforced friction materials

“…The results showed that the treated composites with 3‐amino propyl trimethoxy silane and the trimethoxy methyl silane had higher thermal stability compared with that of untreated composites; and jute fiber composite treated by trimethoxy methyl silane, which had better fiber substrate adhesion, exhibited maximum abrasive wear resistance. Ma et al investigated the effect of jute fibers contents on the friction and wear properties of the friction materials. They indicated that the friction coefficients of friction materials reinforced with jute fibers of 3 wt %, 6 wt %, 9 wt %, and 12 wt % decreased with the decrease in temperature in cooling condition.…”

Evaluation of the Mechanical and Tribological Behavior of Polyether Ether Ketone Fiber-Reinforced Resin-Based Friction Materials Fabricated by Wet Granulation

“…It could be inferred that the incorporation of PEEK fiber can reduce the sum of SWR by 13.51%–52.86% and PFS-6 had the optimal wear resistance. Furthermore, the wear resistance of RBFMs strengthened by PEEK fiber was higher than that of RBFMs strengthened by glass fiber [ 39 ], jute fiber [ 40 ] and corn stalk fiber [ 21 ].…”
