A method of 3d braided composites damage monitoring

摘要：

　　L shaped braided composites under fatigue load was researched,using piezoelectric sensors and active Lamb wave monitoring technology.HHT transform based signal envelope obtaining method and the damage index method based on signal energy change were used to monitor the damage extending of the braided composites.

关键词： Lamb wave braided composites damage index HHT transform
