摘要
Abstract
As a new nondestructive detection method ,laser ultrasonic ,which gradually goes into our sight ,is non‐contact ,point detection and have the significant advantage in the complex shape sample test with high effi‐ciency .The principle and advantages of laser ultrasonic technique is introduced ,and the composite laminates specimen with preset injury is made .The penetration method and pulse reflection method are used to test the sample ,which is composite laminates containing a preset damage .Results show that φ2 mm preset defects could be detected by both methods ,which can reach the same detection‐rate as a ultrasonic test system with a conventional piezoelectric probe .关键词
