本文比较了使用不同的热无损检测技术来快速检测碳纤维复合材料飞机部件。制备了模拟碳纤维增强塑料层合板中夹杂物和几乎不可见的冲击损伤的样品，这分别代表了制造过程和使用环境中的缺陷。材料缺陷检测的限制，然后比较瞬态和锁定热成像和结果进行了验证与水下超声c扫描。本文的结论是，锁相热成像是一个更强大的技术来检测冲击损伤和瞬态热成像更适合于检测夹杂物。热无损检测比水下超声波c扫描快30倍，最终可能为商用飞机部件的快速定量在役和制造过程检测问题提供解决方案。(C)2000爱思唯尔科技有限公司版权所有。
This paper compares the use of different thermal non-destructive testing techniques to rapidly inspect carbon fibre composite aircraft components. Samples were prepared to simulate inclusions and barely visible impact damage in carbon fibre reinforced plastic laminate which represent faults in tho manufacturing process and in-service environment respectively. The limits of material fault detection were then compared for transient and lock-in thermography and the results were verified with underwater ultrasonic c-scans. The paper concludes that lock-in thermography is a more powerful technique to detect impact damage and that transient thermography is more suitable for detecting inclusions. Thermal non-destructive testing is up to 30 times quicker than underwater ultrasonic c-scanning and may ultimately provide the solution to the problem of rapid quantitative in-service and manufacturing process inspection of commercial aircraft components.
