The effect of erodent particle size on solid particle erosion of randomly oriented short glass fiber and mineral particle reinforced polyphenylene sulfide (PPS) was investigated. To examine the effect of erodent size on the erosion resistance of the PPS composite, aluminum oxide particles at three different sizes, namely, 300-425 mu m, 150-212 mu m, and 45-75 mu m, were used. The erosion tests were performed at six different contact angles of 15 degrees, 30 degrees, 45 degrees,60 degrees, 75 degrees, and 90 degrees, respectively. The results showed a strong relationship between the erodent particle size and erosion rates of PPS composite. Maximum erosion rate for the erodent particles with sizes of 45-75 mu m and 150-212 mu m occurred at contact angle of 30 degrees, on the other hand maximum erosion rate for particles having 300-425 mu m size occurred between 45 degrees and 60 degrees. The morphologies of eroded surfaces were characterized by the scanning electron microscopy (SEM). Possible erosion mechanisms were discussed. POLYM. COMPOS., 31:985-994, 2010.
