A critical review on erosion wear characteristics of polymer matrix composites

Abstract

Polymer matrix composites (PMCs) are extensively known for their higher strength and stiffness at lower weight compared to traditional materials. They are extensively used in numerous engineering applications. Utilization of these materials had been extended to novel areas where it is essential to study their tribological performance. Several research works reported the tribological performance of polymer composites. The aim of the review is to provide broad information on erosion behaviour of polymeric composites. Attention is paid towards the effect of test parameters i.e. impact velocity, erodent characteristics, impingement angle on the erosion wear rate and their failure mechanisms were discussed. Inclusion of various fillers in to polymeric composites enriched the erosion resistance property that attracted the researchers to find out their application. However limited literature were available on the erosion behaviour of particle filled composites. Hence, another objective is to review available literature on the erosion response of filled composites.

A review on the degradation of properties under the influence of liquid medium of hybrid polymer composites

“…Wear is unnecessary damage to the surface of a solid due to its relative motion, which entails the partial loss of material from the contacting surfaces. It is a natural reaction of a substance that may either be mechanical or chemical [56]. One of the principal causes of material failure and damage to equipment is identified as friction and wear [57][58][59].…”

Hybrid polymer matrix composite (UHMWPE‐HPMC) as solid particle erosion resistant coating for sharp pipe elbows using numerical simulation and experimental analysis

“…Composite coatings can be designed to have more complicated failure mechanisms, which influence their functional properties at these conditions. [3][4][5][6] Ceramic particles reinforced polymer matrix composites (PMCs) have shown erosion mechanisms like removal of matrix resin from the surface by the continuous impacts of erodent. This results in exposure of ceramic particles or impacts of erodent on the particles.…”

“…This also causes crack formation in particles and propagation into the base metal and separation of composite coating-base metal along the interface. 2,[7][8][9] The erosion resistance of PMC coatings is affected by parameters of the environment such as shape and size of eroding solids, impact velocity at contacting angle, 4 impacting flux rate and ceramic filler parameters in the composite coating like content, 6 size orientation, and hardness profile. [10][11][12][13] For PMC composite coatings, the factors affecting the SPE can be categorized to the nature of hybrid polymer matrix, ductility, and quality of different interfaces like particle-matrix or matrix-metal.…”

“…7 These simultaneous effects of modes lead to lateral crack propagation in brittle mode and microdamages accumulation and fatigue impact in ductile materials. The impact energy can be categorized in normal (elastic impact), 4 normal (plastic impact), 6 normal (elastic/plastic impact), and oblique (elastic/plastic impact). 10 Normal elastic/ plastic impact is the most common, which is a combination of elastically released kinetic energy and heat due to internal friction.…”

“…When sharp edged particles are present in the environment, the mechanism changes to microcutting and plowing (oblique). 11 The introduction of hydride PMCs for wear resistance purposes 17 has showed that the synergic effect of different size/morphology reinforcement additives is substantial. As the erosion performance depends on matrix and reinforcement bonding, 18 an improved bonding strength can increase the hardness of composites and therefore the erosion resistance.…”
