In this study, an
investigation on solid particle erosion performance of transparent
polycarbonate solid sheet, plexiglass and two types of laminated materials,
which are widely used in aerospace and automotive industries, were performed.
All the experiments were performed using tests system developed as per ASTM
G76-13 and MIL-STD-3330 solid particle erosion test standards. The influence of
impact angle (20°, 30°, 45°, 60° and 90°) and impact velocity (70, 150 and 195
m/s) were taken into consideration on solid particle erosion behavior of
investigated materials. Besides these test parameters, alumina (Al2O3 – 52 µm)
and silica sand (SiO2 – 71 and 348 µm) with different particle diameters were
used as impinging erodent particle. Polycarbonate material showed better
erosion resistance at all velocity and impact angle parameters when compared to
other materials. In addition, polycarbonate material represented an incubation
behavior at low velocity tests performed with smaller silica sand size. Impact
angle of 30°, both polycarbonate and laminated glass materials exhibited.
Erodent particles impinging to laminated glasses changed impact angle at
laminar transition.
