Wear resistance and friction behavior of thermoset matrix reinforced with Musaceae fiber bundles

Influence of tribological test on the global conversion of natural composites

“…Resin, hardener and fiber bundles were mechanically mixed, then the mix was put in a mold and compressed at 1000 psi. The curing condition corresponds to 100 °C during 1 h, these conditions were defined according with previous work [35] . This condition was chosen in order to explore potential variations of curing conversion of vinyl ester resin after the tribological test.…”

“…Pins were machined to reach a diameter of 6.3 mm. The tribological test was performed using a pin on disc machine as the one schematized elsewhere [35] . According to this previous study, the most adequate parameters of the experiment test corresponds [35] : 200 m min −1 of speed, recorded distance corresponds to 3 km, and normal load to 4.9 N. The counter body used was a 1040 steel, a common material for the evaluation of the tribological behavior of polymers.…”

“…Additionally to neat matrix, natural composites reinforced with natural fibers such as Musaceae fiber bundles are considered. The use of this type of fiber bundles is due to the interesting qualities of their composites for the tribological applications, that have been evaluated in previous work [25,35] .…”

Investigation on wear behaviors and worn surface morphology of surface treated palmyra fruit fiber/polyester composites to appraise the effects of fiber surface treatments

“…Expansion Narration References A Adhesion When two bodies are under sliding with each other, mass from the soft body may stick on the counter surface and then removed due to higher shear stresses. [19,20,26,28] FD Fiber debonding The raw natural fiber surface always having the deposits of wax, impurities and other decomposable substances. These deposits prevent the better bonding of fiber with polymer matrix and leads to debonding under load.…”

“…The silane residues present in the fiber surface after the silane treatment are acting as bi‐functional groups, that is, they are able to react with both polymer matrix and natural fibers. This phenomenon ensures the drastic improvement in the fiber–matrix interfacial bond strength that cannot be achieved by the untreated fiber reinforced composites . Apart from the fiber surface treatment, the fiber content next finds a notable role in wear behaviors of the natural fiber polymer composites.…”
