“…A number of investigators have found that the erosion rate of particle reinforced composites depends not only on reinforcement volume fraction, but also on reinforcement size. [ 7,25 ] Therefore, in this study two different reinforcement sizes were used. Approximately spherical zirconia particles (Shanghai Zhimo New Material Technology Co., Shanghai, China) in two sizes were used as reinforcements, and Epikote MGS LR 235 resin with a MGS LH 234 hardener (Hexion Columbus, OH) was used as the epoxy matrix phase.…”

“…The choice of this matrix and these particle sizes facilitated comparison with the results of our earlier alumina particle‐reinforced epoxy study, where spherical particles in two sizes of 197 and 447 μm were used as the reinforcements. [ 7 ] As discussed by Plueddemann et al in, [ 26 ] since inorganic ceramic particles were used to reinforce the organic epoxy, a silane coupling agent (KBM‐ 603, Shin Etsu, Chiyoda, Tokyo, Japan) was used to enhance the interphase bonds.…”

“…Their in‐plane size distribution and thickness distribution can be found in our previous studies. [ 7,18 ] Arani et al [ 7 ] found that when these abrasive particles were used, the fracture of the brittle alumina reinforcements was a dominant erosion mechanism. Therefore, this abrasive particle size was again used in the present study in order to allow an assessment of whether the presently used tougher zirconia reinforcements would improve the erosion resistance.…”

“…Composite samples with volume fractions of 35% and 45% of zirconia reinforcements were fabricated using the same methodology described by Arani et al [ 7 ] These volume fractions were again chosen to be identical to those of the alumina reinforcements in Arani et al's paper, [ 7 ] thus allowing for a direct comparison of the relative erosion resistances when using the two ceramic reinforcements. The nearest neighbor theory [ 27 ] was employed, to analyze the distribution of reinforcements in the fabricated samples, by taking 20 images from the surface of the uneroded samples.…”

“…For example, Saputra et al [ 6 ] investigated the erosion of glass bead‐reinforced epoxy composites by glass particles and observed a significant deterioration in the erosion resistance compared to the neat epoxy due to the fracture and removal of the reinforcements. Arani et al [ 7 ] studied the effect of adding spherical alumina particles to an epoxy matrix on the erosion of the resulting composite by the high‐speed impact of silicon carbide abrasive particles. Using three dimensionless ratios that depend on process parameters such as the abrasive size, the abrasive kinetic energy, the reinforcement size, the reinforcement content and the material properties, they identified, categorized, and discussed the typical erosion mechanisms occurring for composites having hard and brittle reinforcements.…”

Numerical and experimental investigation of the erosion of zirconia particulate‐reinforced epoxy matrix composites by angular silicon carbide particles

et al. 2020

An smooth particle hydrodynamics/finite element (SPH/FEM) model was developed to simulate the erosion of zirconia particle‐reinforced epoxy composites, due to the overlapping impacts of angular particles at both perpendicular and oblique incidences. For each composite target, multiple sub‐volumes, each having their own random reinforcement distribution, were modeled. The reinforcements were assumed as noneroding and nondeforming and were distributed in the modeled sub‐volumes according to the random distributions measured in the actual samples. Erosion tests were performed to verify the numerical model, and it was found that the erosion rates of the zirconia‐reinforced composites were in all cases significantly lower than the neat epoxy. The experimentally‐observed erosion mechanisms were successfully simulated by the model, and the predicted erosion rates matched the measured ones to within 2% to 11%. It is anticipated that similar models can be used to predict erosion of other particulate composite systems whose reinforcement erosion and fracture is negligible compared to the matrix erosion.

Present investigation characterizes solid particle erosion response of neat epoxy and crump rubber filled epoxy composites. Three types of composites were prepared by reinforcing crump rubber particles (10, 20 and 30 vol.%) in epoxy matrix. Neat epoxy samples were also prepared for comparison. Thermo gravimetric analysis revealed crump rubber composites have higher stability as compared with neat epoxy specimen. Differential scanning calorimeter tests reveal higher glass transition temperature for crump rubber composites as compared with neat epoxy specimens. Erosion rate of the samples have been studied for different angles of impingement (30, 45, 60 and 90°) and erodent impact velocity (30, 45 and 60 m/s). 30 vol.% of crump rubber reinforced epoxy composites reveal better resistance to erosion in comparison with other composites and neat epoxy; attributed to the elastic nature of crump rubber particles to absorb impact energy of erodent particles. For all the specimens, maximum erosion is noted at 60° angle of impingement indicating semi‐ductile response to erosion. Erosion efficiency and velocity exponent of samples also substantiate the semi‐ductile behavior. Morphology of the eroded surfaces was analyzed using scanning electron microscope. Property map is used to compare the results available from the literature with the present study.

This paper aims on evaluating the erosion wear behavior of epoxy composites reinforced with ramie fibers. The possibility of reinforcing ramie fiber to improvise the wear resistance of epoxy is investigated in this study. Composites are fabricated by reinforcing multiple layers of woven ramie fiber mats into epoxy resin using conventional wet lay‐up technique and erosion wear trials are conducted using solid particle erosion test setup. Taguchi analysis is done to assess the relative significance of each of the factors influencing the erosion rate using L16 orthogonal array. The analysis reveals that the impact velocity followed by impingement angle are the most significant control factors affecting the erosion wear rate of ramie‐epoxy composites. Steady state erosion analysis is done to ascertain the effect of each of the significant factors while keeping other factors fixed. Further, an analytical and predictive model based on the principle of neural computation is used to predict the rate of erosion wear of the composites and the obtained results are compared with the experimental outcomes. The worn morphologies of the eroded surfaces of the composites are studied and analyzed to identify possible mechanisms causing wear.
