“…Fv is responsible for the impact phenomenon, at normal impact, all energy is dissipated by micro-cracking and impact. 40,43 Indicating that different types of materials, like ductile and brittle, exhibit different angular dependencies. 2 Maximum erosion in ductile materials occurs at low oblique impact angles in the range of 15°-30°.…”

Modern-day engineering applications favor polymers and polymer composites on the grounds of their high specific properties. They can offer many different advantages compared to metals; such as high strength-to-weight ratio, ease of production, but their erosion resistance is weaker. In polymer composites, material loss occurs because of high-speed and repeated exposure to erosive particles, therefore service performance and life of the parts are adversely affected. Due to this, it is crucial to predict the particle erosion that may occur in engineering applications and to know the erosive wear behavior of the materials well. Polytetrafluoroethylene and its composites are widely used in tribological applications because of their load-carrying capacity, self-lubricating, and low-density properties, but there is inadequate literature on particle erosion behavior. In this study, particle erosion behaviors of polytetrafluoroethylene, its randomly oriented short glass fiber, and carbon particle and bronze particle-reinforced composites were investigated under different test conditions. Two different types of erosive particles (garnet and alumina) were used to present the effect of erodent type on particle erosion behavior. After particle erosion tests, surface topographies were examined by an optical profilometer, and surface morphologies were examined by scanning electron microscopy. It has been found that the type of reinforcement and the type of erodent significantly affects the particle erosion behavior of polytetrafluoroethylene and its composites.

“…In the tests carried out at impact angle of 85°( figure 11(b)) there was greater wear in samples with gelcoat, this is because the gelcoat has a lower hardness and the angular sand particles remove the material quickly [31]. Erosion damage at 90°is regularly maximum [32][33][34], because the erosive particles impact perpendicularly to surface of the material. In figure 11(c) it was observed that the mass loss from erosion wear at 90°is greater in all materials, this confirms the brittle erosion behaviour and results in a rougher surface after the tests [35].…”

In this research work, temperature erosion wear tests, on composites materials (carbon fiber and glass fiber), were carried out. The tests were made on uncoated and coated materials using a polyester resin (Gelcoat), which is used to protect the leading edge of wind turbine blades against the weather and UV rays and is of interest, in this study, to know the behaviour of this coating subjected to hard particles erosion. The tests were performed at 50°C, in order to simulate de extreme temperature in the coast of Oaxaca, Mexico, where some wind turbines are installed using blades made of fiberglass coated with gelcoat. Erosion tests were performed in a platform that was developed from the ASTM G76 standard. The rectangular samples had 25×18 mm and thickness of 4 mm. Sea sand from coast of Oaxaca was utilized as erosive particle. Three different impact angles were used 75°, 85°and 90°. The particle velocity was adjusted at 12 m s −1 . To determine the mass loss, the samples were weighed before the test and reweighed every 2 min to measure the amount of mass loss until complete the 6 min of the test. In order to identify the wear mechanisms, Scanning Electron Microscopy was used. The average roughness (Ra) and profiles of the samples tested were determined with a 3D optical profilometer. The results showed that Carbon fiber composite material had 3 times more resistance to erosive wear than fiberglass.

“…The advances in material sciences has influenced researches to explore the erosive performance of advanced fiber reinforced polymer composite in which fiber and filler exists together as reinforcement to the polymer matrix. Studies by Mahesha et al, Joshi et al, Rao et al, and Ray et al [6], [14], [15] focused on solid particle erosion behavior of these materials with variable factors of erodent concentrations, erodent size, impingement angle, speed, and temperature.…”

The present study aims to investigate slurry pot erosion wear behavior of nanoclay-modified short fiber reinforced polymer (SFRP) composites. Epoxy matrix modified with 5wt% nanoclay was prepared using high shear three roll milling mixing system at 60°C and 12.7 m/s speed. Two short synthetic fibers and two short natural fibers were used as reinforcements, i.e. carbon, glass, basalt, and kenaf. Slurry pot erosion wear tests were conducted using a mixture of sand and water as erosive materials and at a running speed of 300rpm for 10km sliding distance. The results showed that the inclusion of short fibres improved the erosion wear behavior of epoxy polymer, in which basalt reinforced polymer composite showing the best performance when compared to the other types of SFRP composites. The addition of 5.0wt% nanoclay filler also reduced the specific erosion wear rate of the SFRP composites. Nanoclay had significantly improved wear rate of glass fiber reinforced polymer composites of up to 53% compared to its pure state. Basalt fiber was also found to be a potential alternative to synthetic fiber; i.e carbon and glass fiber, based on its lowest wear rate among all the SFRP composites.
