AbstractThe erosive wear behaviour of epoxy composites reinforced with aligned, as-produced carbon nanotube (CNT) films was investigated. The CNT film composites were fabricated in two different configurations, where the unidirectional (0°) and bi-directional (0°/90°) aligned CNT films were exposed to the particle stream. Results have shown that the unidirectional (0°) CNT film/epoxy composite exhibit superior erosive wear resistance compared to the unidirectional (0°) carbon fibre reinforced epoxy composite.Furthermore, the bi-directional (0°/90°) CNT film/epoxy composite shows even better resistance to erosion compared to the unidirectional (0°) CNT film/epoxy composite due to additional impact energy absorption resulted from CNT networks. Scanning Electron Microscopy (SEM) provides further insight into the erosive wear mechanisms of CNT film composites at different impingement angles. This work has successfully introduced aligned as-produced CNT films fabricating epoxy composites using

Tribological behaviour of fibre-reinforced thermoset polymer composites: A review

“…Chen et al. 39 carried out experiments regarding erosion on unidirectional CF/EP composites as well as unidirectional and bidirectional CF/EP composites, filled with aligned carbon nanotubes (CNTs). The experiment data showed the maximum erosion wear rate at 30°–45° impingement angles for CNT film-reinforced epoxy composites, implying ductile erosion behaviour.…”

Influence of fiber orientation on solid particle erosion of uni/multidirectional carbon fiber/glass fiber reinforced epoxy composites

“…Meanwhile, advanced scientific researches on these materials are progressively carried out. 1–6 Erosion wear is formed when solid particles moving at a certain velocity impact a surface and remove some materials off the top surface. Impingement angle (15°–90°), 7,8 velocity (≈16–88 m/s), 9 size (≈42–500 µm) and shape (spherical and angular) of the impacting particles (Garnet, SiC, Al 2 O 3 , and SiO 2 ), 10 as well as the properties of target material 11–13 are important variables that affect the solid particle erosion behavior.…”

Micro Hardness and Erosive Wear Behavior of Tungsten Carbide Filled Epoxy Polymer Nano Composites

“…15 0 -30 0 ) then the erosion failure mode of a material is ductile in nature, On the contrary, if maximum rate of erosion occurs at higher impact angles (i.e. 70 0 -90 0 ) then the erosion failure mode of a material is brittle in nature (Arnold and Hutchings, 1992;Arnold and Hutchings, 1993;Zhou et al, 2013;Chen et al, 2014).…”

“…Based on the worn surface, they explained the failure phenomena. Chen et al (2014) observed erosion wear performance of carbon nanotube (CNT) film composites, which had two different orientations (uni-directional-0 0 , bi-directional-0 0 /90 0 ). Results show that unidirectional composite exhibits better erosion wear resistance than bi-directional composite.…”
