玻璃钢缺陷的空耦激光超声检测
Air-coupled laser ultrasonic testing of glass fiber reinforced polymer defect
摘 要
玻璃钢具有优异的材料性能而被广泛应用于航空航天等领域,但在生产和使用阶段产生的缺陷会极大影响材料的稳定性和安全性。使用传统无损检测手段检测具有各向异性、层铺结构的玻璃钢时存在一定局限。使用结合激光超声与空耦超声检测优点的混合系统,采用中心频率为450 kHz的低频空耦探头,非接触检测了玻璃钢内部不同类型的微小缺陷,并开展了接触式相控阵超声检测对比试验。试验结果表明,使用混合系统能够有效实现玻璃钢内部缺陷形状、尺寸及位置的低成本、非接触和高精度检测。

Abstract
Glass Fiber Reinforced Polymer (GFRP) composites are widely used in aerospace and other fields due to their excellent material properties. However, defects generated during the production and usage phases can greatly affect the stability and safety of the GFRP composites. Traditional non-destructive testing methods have certain limitations when they are applied to the internal defect detection of GFRP composites with anisotropic and layered structures. To address the material inspection challenges of GFRP, we have developed a laser ultrasonic inspection system based on a low-frequency air-coupled ultrasonic probe that can retain the high resolution of the laser ultrasonic inspection system with low-cost and high robustness of the air-coupled ultrasonic probe. In this paper, using a hybrid system combining the advantages of laser ultrasound and air-coupled ultrasound inspection, different types of minor defects in glass fiber reinforced composites were non-contact detected using a low-frequency air-coupled ultrasonic probe at 450 kHz, and the results were compared with those of contact ultrasound phased array inspection. The results show that the use of the hybrid system can effectively achieve low-cost, non-contact, high signal-to-noise ratio and high accuracy detection of the shape, size and location of defects in GRFP composites.
