“…Among the conclusions mentioned above, the conclusions (a), (b), and (c) are very common findings that many researchers were already pointed out. 11,15,16,19,20,27 Considering that the CF composite has lower density than the GF composite under the condition of the same fiber weight content, the conclusion (d) was the same as Miyazaki and Hamao 20 pointed out in their preceding research.…”

This article presents a critical review of papers dealing with solid particle erosion characteristics of polymer matrix composites, metal matrix composites, and ceramic matrix composites. In addition, the solid particle erosion characteristics of coatings for composite materials are also reviewed. Attention was paid to type of a reinforcement material (fiber/filler), amount of fiber/filler, fiber orientation, and interfacial strength between fiber/filler and matrix, which affect the solid particle erosion in addition to the variables affecting the solid particle erosion of monolithic materials, that is, impact angle, particle velocity, temperature, particle flux, and erodent properties such as shape, size, hardness, and so on. General characteristics of solid particle erosion for composites are extracted from the review of the papers.

“…Ballout et al. 19 performed solid particle erosion experiments of unidirectional GF epoxy composites, GF/EP, the fiber and matrix weight ratios f / m ( f : fiber weight, m : matrix weight) of which were 65/35, 50/50, and 35/65. Erosion experiments were performed at the impact angle α varying from 10° to 90°.…”

“…The linear (LROM) and inverse (IROM) rules of mixture were proposed and evaluated for a multiphase Al-Si alloy. The same rules of mixture were adopted by Ballout et al [70] for a glass-fiber reinforced epoxy composite. These two rules of mixture were also proposed to model the abrasive wear of unidirectional (UD) fiber reinforced composite materials [71,72].…”

The solid particle erosion behavior of polymer composites has been reviewed. Attention is paid to the effects of testing variables (e.g., erodent type, impact angle, impact velocity) on the erosion wear rate. The occurring failure mechanisms are discussed. Various predictions and models proposed by different investigators to describe the erosion rate (ER) are listed. Implementation of design of experiments (DOE) and statistical techniques in analyzing the erosion behavior of composites is reviewed. Recent findings on erosion response of multi-component hybrid composites are also presented. Recommendations are given to solve some open questions related to hybrid polymer composites.

“…They also observed that both the inverse and linear rules of mixtures failed to accurately predict the erosion rate when 406 µm abrasive particles were used, leading them to conclude that rules of mixtures are applicable only if the size of the impact zone (10% -20% of the abrasive particle size) is less than the size of the composite microstructure. Ballout et al [110] used these mixture rules to predict the erosion rate of a glass fiber-reinforced epoxy composite eroded by 142 µm alumina particles, and found a better agreement with experiments when the inverse rule was used. Fang et al [111] modified the inverse rule of mixtures by taking into consideration the synergistic effect of the phases and presented two models for two different ranges of impact angles.…”

Polymeric composites are exposed to erosion by solid particles in many different applications in various industries. The objective of this dissertation is to understand and model the material removal mechanisms occurring when particle-reinforced epoxy composites are subject to solid particle erosion. Experiments on alumina particulate-reinforced epoxy composites using angular silicon carbide abrasive particles revealed that the dominant erosion mechanisms depended, to a large extent, on the magnitude of three dimensionless parameters. These parameters depended on process variables such as abrasive particle size, kinetic energy, reinforcement size, content and material properties. It was also observed that the use of coupling agent was effective in strengthening the composites interfacial strength leading to improving their erosion resistance. It was found that with alumina reinforcements, reinforcement erosion and fracture resulted in little to no improvement in erosion resistance compared to the neat epoxy. However, when soft rubber or zirconia reinforcements were used, significant gains in erosion resistance were observed. For the rubber reinforcements, a novel rule of mixtures based on the erosion rates and areal coverages of the two phases is proposed. Using a model that was developed to predict the areal coverages given the reinforcement size and volume fraction, the mixture rule was shown to accurately predict the measured erosion rates. To better understand the erosion mechanisms of the zirconia-reinforced system, numerical models of the erosion of the neat epoxy and composite were developed. Using smoothed particle hydrodynamics (SPH) coupled with finite elements (FE), the developed model correctly predicted the measured neat epoxy steady-state erosion rate, incubation period length, and dominant erosion mechanisms. The SPH/FE model of the zirconia-reinforced composites assumed that, because of their relatively high fracture toughness, the reinforcements did not fracture. The model accurately predicted the significant improvement of the erosion resistance and the erosion mechanisms associated with using these tougher ceramic particles, at both oblique and perpendicular incidences. The methodologies presented in this thesis aid in determining the process and material parameters that most affect the erosion of particulate composites and, therefore, can be used in the material design process to improve erosion resistance. Although only particle-reinforced epoxy matrix-systems were studied, it is likely that many of the same phenomena will be present in other particulate polymer-matrix composites.
