摘要：

Fatigue failure of the mechanical parts has always been paid great attention to in mechanical engineering. In recent years the study on the self-healing composite materials with microcapsules provides a new way to solve it. In this paper, the fracture mechanics analysis on the self-healing composite material with microcapsules used for gear is carried out to determine whether it can achieve the self-healing. The results show that, only when the fracture toughness of the capsule shell and that of matrices matches in some way, can the self-healing be achieved. The composite material made of nylon 6 (PA6) as the matrix material, short E glass fiber as the reinforced material, poly ( urea-form aldehyde) encapsulated dicyclopentadiene (DCPD) as the self-healing microcapsule, is studied in this paper. The results show that this formula is feasible.
