In this study, a water jet erosion test setup was used to evaluate the erosion resistance of glass fiber-reinforced polymer (GFRP) composites. The erosion tests were conducted using GFRP composite coupons of size 40 × 40 × 4 mm. The erosion test parameters included jet impact angles of 30°, 45°, and 90° and test durations of 120, 240, and 360 min. Fresh water and 3% NaCl saline water solutions were used as erodent medium in the present study. The test results were obtained as mass loss and mass gain. The eroded GFRP surface was analyzed using scanning electron microscopy (SEM). The dominant erosion mechanism was ductile–brittle erosion, which was evident from the presence of matrix deformation and fiber breakage in the eroded coupons.

摘要

In this study, a water jet erosion test setup was used to evaluate the erosion resistance of glass fiber-reinforced polymer (GFRP) composites. The erosion tests were conducted using GFRP composite coupons of size 40 × 40 × 4 mm. The erosion test parameters included jet impact angles of 30°, 45°, and 90° and test durations of 120, 240, and 360 min. Fresh water and 3% NaCl saline water solutions were used as erodent medium in the present study. The test results were obtained as mass loss and mass gain. The eroded GFRP surface was analyzed using scanning electron microscopy (SEM). The dominant erosion mechanism was ductile–brittle erosion, which was evident from the presence of matrix deformation and fiber breakage in the eroded coupons.
