Abstract:

In this study, two different composite pipes manufactured with filament winding technique in [±55]4 winding configurations were investigated by considering the erosive behaviour of the inner surface of the pipe which may be subjected to erosive wear in substructure and material transfer applications where may be worn because of material flow. The solid particle erosion behaviour of basalt fibre reinforced composite pipe (BETKB) and basalt fibre reinforced composite pipes reinforced with 0.25 wt % graphene nanoplatelets (GNP/BETKB) were compared by considering the results obtained from the experiments. When evaluating the erosion rate resulting from impacting alumina abrasive particles on the inner surface of a pipe at various impact velocities (namely 23 m/s, 28 m/s, 34 m/s, and 53 m/s) and impingement angles (30, 45, 60), it was observed that graphene nanoplatelets reinforcement increased the resistance to erosive wear in basalt fibre-reinforced pipes. As indicated by the graphs, which also analyse the proportional change in erosion rate, the graphene nanoplatelets reinforcement achieved an erosion rate reduction of almost 50% at the impact velocity of 28 m/s. It was observed that the wear model of both pipes showed a behaviour suitable for the semi-ductile wear model.
