Abstract
According to the characteristics of the bonded structure of CFRP skin-CFRP,short pulse ultrasonic reflecting on-equipment testing method was used to test bonding quality,the influence of bonding film and debonding in structure on ultrasonic reflecting signal were analyzed,and self made short pulse delay block ultrasonic probe was used to test debonding in samples.Simulation results show that,short pulse ultrasonic reflecting signal can test Ⅰ interface debonding Ⅱ interface debonding when d/λ ≤0.5.Experiment results show that,the width of pulse produced by self made 5 MHz probe is not larger than 1.5 cycle,which can meet the requirement of short pulse.The self made probe can test Ⅰ interface debonding,and Ⅱ interface debonding when thickness of bonding film is less than 0.5 mm,which can meet on-equipment testing requirement of actual product.关键词
