The Influence of Fibre Orientation on Tribological Performance of Jute Fibre Reinforced Epoxy Composites Considering Different Mat Orientations

Abstract

In this study, hand lay-up technique was used to fabricate epoxy composite based on jute fibre mates. Three different orientations wew considered in the fabrication of the composites. The characteristics of the material removal from the surface of the composite due to sliding condition was investigated. Different applied loads were considered to gain different shear force in the interface. Scanning electron microscopy was used to examine the influence of the shear force on the interaction between the fibre and the resin after sliding at different orientations. The outcome would be significantly contributed to the knowledge of composite science and tribology. The main findings of the work was that fibre orientation has very significant influence of the wear and frictional performance of jute fibre reinforced epoxy composites. Sliding distance controls the running in and steady state wear behaviour of the composites especially when the composite was tested in parallel and antiparallel orientations. Wear resistance of the composites found to be better in the antiparallel orientation followed by parallel and then normal. Jute fibres gave very promising results to replace glass fibres for the same composites at the same operating conditions.

Biofiber‐reinforced polymeric hybrid composites: An overview on mechanical and tribological performance

“…It was observed that incorporating the jute fibers in polypropylene matrix lowered the specific wear rate by 65%. Alshammari et al [98] studied the tribological properties of jute-epoxy composites subjected to different fiber orientations. For the enhancements in surface properties, jute fibers were immersed in 6% NaOH solution for 24 hours following which they were cured in an oven for 24 hours at 40 C. Using block on ring setup, the effect of composite specimens in normal, PO and APO orientations were analyzed.…”

Tribology of Natural Fibers Composite Materials: An Overview

“…Considering the fiber orientation and fiber content, as presented in Table 3, Acha et al [70] reported the compressive properties of unsaturated polyester reinforced with raw, acetone-washed, and detergent-washed jute fibers. Considering the effect of fiber orientation on the material wear performances, respect to the sliding directions, Alshammari et al [44] investigated jute/epoxy composites using block-on-ring (NFRC vs. stainless steel) configuration under dry contact conditions. The AP-O fibers showed a better film generating on the contact surface and a high shear resistance, allowing the authors to conclude that the AP-O fibers within epoxy matrix exerted a high friction coefficient (0.72 ± 0.13).…”

“…As schematically shown in Figure 2 and clarified by many authors [40][41][42][43][44][45], with respect to the sliding direction, three fiber orientations within composites should be defined in a tribological contact: (a) Parallel orientation (P-O), (b) anti-parallel orientation (AP-O) and (c) normal orientation (N-O).

“…Mechanical properties of some natural fibers compared with Aramid and E-glass fibers [38,39]. As schematically shown in Figure 2 and clarified by many authors [40][41][42][43][44][45], with respect to the sliding direction, three fiber orientations within composites should be defined in a tribological contact: The presented fiber orientations and their influence on the tribological properties of the NFRCs will be discussed in Section 3.…”

Tribological Investigation of Frictional Behaviour of Mild Steel Under Canola Bio-Lubricant Conditions

“…Two physical phenomena are set up when two surfaces with relative motion between them are in direct contact. However, surface roughness causes the points on the surfaces to make contact in discrete positions and this creates interfacial adhesion [5,6]. Then friction occurs when the two surfaces move in relation to one another.…”
