Effect of GnPs on Erosion Wear of BFRP Composite Pipes Under High Temperature Conditions

Basalt fiber reinforced polymer (BFRP) composite pipes were reinforced with 0.25 wt% graphene nanoplatelets by ultrasonic mixing technique. Solid particle erosion tests were carried out at 23 °C, 50 °C and 100 °C and different impingement angles (30°, 60°, 90°). The highest erosion rate in Basalt pipe was at 90° erosive particle impingement angles, while in graphene nanoplate reinforced pipes, this rate was realized at 60° and 90°. In other words, at 23°C, the erosion resistance gain achieved with graphene addition was 1,52-2,89 times greater depending on the impact angle, but even experiments conducted at 50°C and 100°C demonstrated a 55% increase in the practical relevance of graphene use. To provide evidence for damage mechanisms based on the detailed data obtained, the focus was on clearly demonstrating the quantitative impact of graphene's presence using scanning electron microscopy. Furthermore, enhanced performance and durability of additive composite materials will pave the way for their widespread use in industrial applications, with sectoral output.
