“…Studies on the fracture mechanism of PRMMC have indicated that the particle fracture dominates the rupture of the composites reinforced by large particles (i.e., d > 20 m), while the interfacial debonding plays a critical role in the case of small reinforcements (i.e., d > 10 m) (Chen and Tokaji, 2004;Gupta et al, 1997;Nie and Basaran, 2005). However, the fracture surfaces in Fig.…”
