Research on Self-diagnose and Self-repair Net in Smart Composite Structure by Hollow-center Optic Fiber

For the damage self repair of the smart composite structure,this paper puts the self diagnose and self repair net in smart composite structure by hollow center optic fiber forth and some key technologies in it are discussed.As passage way of liquid cement,the hollow center optic fiber net can diagnose the loads acting on the structure,put the cement to damage and repair it when structure is damaged.So,the self diagnose and self repair function of the composite structure will be come true
