In this paper, an attempt has been made to study the erosive wear property of CNT reinforced poly methyl methacrylate (PMMA) composites. Carbon nanotubes are (CNTs) applied widely as reinforcing fillers due to their exceptional stiffness and strength, high aspect ratio. The composites have been prepared with different weight percentage of CNT like 0.1, 0.3, 0.5, 0.7 and 1%. The erosion rates of these composites have been evaluated experimentally with regard to their wear rate at three different impingement angles (30⁰, 60⁰, 90⁰) and at three different pressures (1, 2, 3 bar). The particles used for the erosion measurements were sand particle with diameter of 400µm. From the results, it is revealed that with increase of fiber content the erosion rate of the composites decreases. The effect of impingement angle and velocity of impact has a significant effect on the erosive wear behavior of the PMMA-CNT composites. To evaluate the test data obtained, an experimental design method based on taguchi has been used.
