The Analysis of Fracture Mechanics on Self-healing Composite Materials with Microcapsules

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.
