摘要：

Solid-particle erosion of bismaleimide (BMI) polymers of various compositions was studied and compared with measured mechanical properties. For angular aluminum oxide erodents of mean diameter 42, 63, 143 or 390-mu-m impacting normal to the surface at 60 m s-1, the erosion rate was found to be a strong function of the size of the impacting particle. Material removal occurred primarily by a process of brittle-fracture-induced damage. However, the results suggest that for the BMI specimens, degradation and plasticity occurred in addition to fracture, and that the occurrence of these phenomena reduced the erosion rates.
