Experimental study on two-body and three-body abrasive wear behaviour of jute-natural rubber flexible green composite

Abstract

The use of laboratory testing has become more significant to assess abrasion resistance in flexible reinforcement of armour and car structural components. In this study, compliant composite with constituents as woven jute fabric and natural rubber (NR) encapsulated in an NR-based B stage cured prepreg were tested for wear due to abrasion under two- and three-body conditions. Flexible composites are fabricated in three different configurations namely Jute/Rubber/Jute (JRJ), Jute/Rubber/Rubber/Jute (JRRJ) and Jute/Rubber/Jute/Rubber/Jute (JRJRJ). The present study makes use of abrasive paper with a grit size of 60 and silica sand with size 250 µm as the abrasive medium for two- and three-body abrasion tests respectively and the specific rate of wear is calculated. Though the wear trend of the composites follows a similar pattern in the case of two- and three-body wear, the mechanisms governing the wear are found to be different. The morphology of the worn surface is studied with the aid of a scanning electron microscope.

Three body abrasion wear resistance of cenosphere particle‐reinforced syntactic foams developed using molding method

“…In a variety of applications, choosing the right lubricants, surface coatings, and reinforcement materials may help PMCs function more tribologically and experience less wear. 8,10,11 One of the most frequent kinds of wear in polymer matrix composites (PMCs) is abrasive wear. When hard objects like sand, dust, or debris come into contact with the PMC surface and cause mechanical damage, it is called abrasive wear.…”

“…In PMCs, the wear mechanisms are intricate and frequently interact with one another. In a variety of applications, choosing the right lubricants, surface coatings, and reinforcement materials may help PMCs function more tribologically and experience less wear 8,10,11 . One of the most frequent kinds of wear in polymer matrix composites (PMCs) is abrasive wear.…”

“…Additionally, the kind of polymer matrix is also very important for PMCs' resistance to abrasive wear. For instance, due to their greater toughness and capacity for energy absorption, thermoplastic matrix composites offer stronger abrasive wear resistance than thermoset matrix composites 10 . Incorporating tougher and more wear‐resistant reinforcing elements, such ceramic particles or fibers, and changing the surface characteristics of the PMC by surface coatings, treatments, or plasma spraying are two methods that may be utilized to increase the abrasive wear resistance of PMCs 14 …”

“…Over the course of their service lives, most engineering components are prone to one or more kinds of wear. 1 Metals and alloys are being replaced with composites in almost every engineering fields in order to minimize component weight and cost. Among the various composites available, PMCs are more commonly employed.…”

“…13 Few researchers conducted assessment of compliant composites for their mechanical properties, which revealed that compliant composites had good resistance to tear. [14][15][16] It was also discovered that by adopting compliant material as a matrix, failure of the component catastrophically may be avoided. 5,17,18 Filler particles have been used to improve the wear resistance of PMCs in recent years.…”
