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.

“…They showed that nano-GFRP has created an opportunity to use this composite in a hydrothermal environment. Improvement in the wear properties of composites reinforced with glass fiber is another important factor that attracted the attention of a lot of studies [ 87 , 88 ]. Öztürk et al [ 89 ] analyzed the erosive wear behavior of the epoxy resin and the glass-fiber-reinforcement was evaluated with respect to the different parameters, such as various impingement angles (from 20° to 90°), velocity in the range of 70–200 mm/s, exposure time and erodent size.…”

Impellers are referred to as a core component of turbomachinery. The use of impellers in various applications is considered an integral part of the industry. So, increased performance and the optimization of impellers have been the center of attention of a lot of studies. In this regard, studies have been focused on the improvement of the efficiency of rotary machines through aerodynamic optimization, using high-performance materials and suitable manufacturing processes. As such, the use of polymers and polymer composites due to their lower weight when compared to metals has been the focus of studies. On the other hand, methods of the manufacturing process for polymer and polymer composite impellers such as conventional impeller manufacturing, injection molding and additive manufacturing can offer higher economic efficiency than similar metal parts. In this study, polymeric and polymer composites impellers are discussed and conclusions are drawn according to the manufacturing methods. Studies have shown promising results for the replacement of polymers and polymer composites instead of metals with respect to a suitable temperature range. In general, polymers showed a good ability to fabricate the impellers, however in more difficult working conditions considering the need for a substance with higher physical and mechanical properties necessitates the use of composite polymers. However, in some applications, the use of these materials needs further research and development.

“…16 The typical dispersion range for the nanosized particles is very less, and also, crack arresting and inhibiting capability is much better than that of microparticles due to increased specific surface area. 17 For example, Wloch et al 18 added 4 wt.% SiO 2 microparticles into the GFRP composite and obtained a 21% reduction in the flexural strength of the structure, whereas Lazar et al 2 obtained a 39.5% increase in flexural strength with 0.75 wt.% addition of SiO 2 nanoparticle within the GFRP composite. As heat dissipation and management in electronics and electrical devices made of polymer composites are problematic issues, electrically insulative and thermally conductive products can be produced by adding nanoparticles into the polymer matrix.…”

“…The inorganic nano SiO 2 particles have been a widely used filler material due to its plenty amount, low cost, excellent heat resistance, nonhazardous effect, better insulation, fine disperse ability, high specific surface area, which leads to enhanced thermo-mechanical, tribological, and physical properties. 1,3,7,17,25 Notably, the low price of nano SiO 2 can provide very cost-effective solutions for the increase of structural performance of the developed composite materials compared to the other counterparts like graphene, CNT, BN, etc. Lazar et al 2 modified the polymer epoxy with SiO 2 nanoparticles at filler loadings of 0.5 wt.%–3 wt.% and maximized the flexural strength with 0.75 wt.% SiO 2 filler which was approximately 40% higher than that of pure GFRP composite.…”

Silicon dioxide (SiO2) nanoparticles can be used as reinforcing material for composites due to their favorable characteristics. However, they are commonly subjected to surface treatments with silane coupling agents to achieve fine dispersibility and better mechanical interlocking at interface. In this study, the silane-coated SiO2 nanoparticles (as received) were used as secondary reinforcement without applying additional silane treatment process. KH550 and KH570 silane-coated SiO2 nanoparticles were dispersed, respectively, into polymer matrix, and then the modified matrix was reinforced with glass fibers. Silanized SiO2 filled glass fiber reinforced polymer (GFRP) nanocomposites were investigated for physical, mechanical, morphological, and thermal properties. Depending on the nanoparticles' ratio and silane coating, the increments were obtained till 10% for tensile strength, between 18.40% and 75.26% for flexural strength, and till 81% for impact strength. SEM confirmed that the enhancements could be attributed to the improved interfacial adhesion between the modified matrix and fiber reinforcements. The void contents within the polymer nanocomposites decreased by 38%–54% compared to a pure one. DSC and TGA examinations revealed that silanized SiO2 nanoparticles provided a better curing behavior (10% increase in Tg for 3 wt.% KH550-SiO2) and improved thermal stability for the GFRP composites (increase in Tend values by 50–70°C). Generally, KH550 silane-coated SiO2 has provided enhanced interface strengthening, leading to better characteristics for GFRP composites since the amino functional groups contained in KH550 have more favorable integration with epoxy matrix.
