Solid Particle Erosive Wear Behavior of Glass Mat Reinforced PPS Composites: Influence of Erodent Particle Size, Pressure, Particle Impingement Angle, and Velocity

Abstract

This study investigates solid particle erosive wear behavior of glass mat reinforced polyphenylene sulfide (PPS) matrix composites under A preliminary draft of this article was presented at the Fifth International Workshop on Thermoplastic Matrix Composites (THEPLAC 2011), various test parameters. PPS composite was manufactured by using the compression-molding process. Composite samples were eroded in a specially designed sandblasting system employing various parameters, and variation of the erosion rate was investigated. Samples were eroded at different erosion times, particle impingement angles, and under various pressures by using three different sizes of alumina particles. Impingement velocities of erodent particles were measured by using the double disk method. The results are also discussed regarding impingement velocity of the erodent particles. Glass mat reinforced PPS composites exhibited semiductile erosion behavior by showing a maximum erosion rate at 30 • and 45 • impingement angles. The erosion rate of the composite was increased with augmentation in erosion time, velocity, pressure, and particle size. Maximum erosion was observed when the composite was eroded after 10 s at 45 • impingement angle under 4 bar pressure by using 60 mesh size erodent particles. The morphology of eroded surfaces was examined by using a scanning electron microscope, and possible wear mechanisms were discussed. C 2012 Wiley Periodicals, Inc.

Tribological performance of polymethyl methacrylate as an aviation polymer

“…Erosion rate was calculated using the formula below: In the present study, the impingement velocities of erodent particles were measured with respect to acceleration/blast gun pressure and particle size by using a double disk method. The double disk method is known as the most widely used method to measure the impingement velocities of particles [11][12][13][14][15][16][17]. Figure 4 shows a schematic illustration of the double disk method used in this study.…”

“…By measuring the distance between the first and the second marks and the distance between the center of the disk and the scar, the angular displacement between the two marks can be calculated (θ). Subsequently, the time of flight of the particles (t) as they travel the distance between the disks (L) can be calculated by using the following formula [17]:…”

Heat treatment effect on erosion behavior of poly(methylmethacrylate) for optical transmittance efficiency

“…Nozzle to sample distance was adjusted as 120 mm. Impingement velocities of erodent particles were measured with respect to acceleration/blast gun pressure and particle size by using the double disc method which is the most widely used procedure [27]. Accelerated particles which have an average velocity of 67 m/s were impacted the both pristine and heat treated PMMA samples for 10 s at various impingement angles (15 • , 30 • , 45 • , 60 • , 75 • , 90 • ) which can be held by adjustable sample holder shown in Fig.…”
