The solid particle erosion (SPE) performance of three different

transparent materials, polycarbonate solid sheet, plexiglass

(Polymethylmethacrylate (PMMA), and laminated glass was investigated.

Erosion tests were performed under different impact angles (20°, 30°, 45°,

60°, and 90°) and impinging velocities (75, 150, and 200 m/s). As erodent

particles, alumina (Al2O3) with 52 μm average diameter and silicon

carbide (SiC), particles with two different dimensions (71, and 348 μm in

diameters) were used. The results showed that polycarbonate specimens

outperformed the other tested samples regardless of impact velocity and

impinging angle conditions. When the erosion resistance of samples at 90°

and 75 m/s is taken into consideration, the polycarbonate sheet was found

to be at least 14 times more erosion resistant compared to plexiglass, and

23 times more resistant than the laminated glass materials. In addition,

polycarbonate exhibited an incubation behavior at lower impact velocity,

and with SiC erodent.
