Solid particle erosion behavior of Graphene/SiC/Al2O3/TiO2 coated Kevlar/Epoxy composite materials

In light of the finding of a research -based solution for erosion with fabrication and test ceramic fillers incorporating composite material, this research used the electro-spun method to cover fibre mats with nanofiller materials such as graphene, SiC, Al2O3, and TiO2. This study delves into the erosive behaviour of recently created nanohybrid composite materials. The test consistently maintains the following parameters: impact velocity (60-80 m/sec), angle of impact (15 degrees - 90 degrees), standoff distance (ranging from 15 mm to 25 mm), and erodent size (ranging from 300 mu m to 500 mu m). The results demonstrated that as the impact velocity and erodent size rose, so did the erosion rate. The semi -ductile quality of the manufactured materials is shown by the highest erosion rate at a 60 degrees impact angle. The smallest erosion rate is often seen at an impact angle of 15 degrees, however. The graphene/ Kevlar/Epoxy, graphene/SiC/Kevlar/Epoxy, graphene/Al2O3/Kevlar/Epoxy, graphene/TiO2/Kevlar/Epoxy, and Kevlar/Epoxy erosion rates range from 3.27 to 13.08, 6.39 to 14.71, 11.64 to 19.30, 13.52 to 23.35, and 22.19 to 51.61 mg/kg, respectively. In comparison to the erosion values reported for hybrid composite materials based on fillers, these numbers are quite low. When compared to a hybrid composite without nanoparticles, the overall weight reduction for graphene/Kevlar/Epoxy, graphene/SiC/Kevlar/Epoxy, graphene/Al2O3/Kevlar/Epoxy, and graphene/TiO2/Kevlar/Epoxy is 70.67 %-85.25 %, 59.23 %-75.38 %, 41.78 %-64.26 %, and 27.86 %-56.91 %, respectively. This research examines the process of morphological erosion. Examining degraded surfaces with a scanning electron microscope reveals microcracks, crack propagation, pushing action, ploughing action, displacement of fibres, and breaking.
