| Summary: | An investigation of the air-coupled ultrasonic technique, which could be done from one side of a testing material, was carried out in order to detect cracks in Fiber Reinforced Plastics (FRP) by non-contacting. The accessibility of probe should be improved to apply this technique for examination of cracks in FRP at maintenance fields of airplane, because in general some obstacles are located on its test surface. In this study, the probe layout was arranged to examine whole test area and some experimental investigation of this technique was carried out using testing specimens. As a result, all cracks located in the testing specimen can be detected clearly. Also it was confirmed that small cracks of 5mm in length could be detected and that the air-coupled ultrasonic technique can be used to detect invisible cracks. |
