聚合物复合材料作为用于车辆和其他构造的结构设计的材料的应用已经导致以安全和有效的方式维护它们。应特别关注飞机结构，其必须是轻质的并且显示出上级机械性能，以满足该行业中不断增长的需求。因此，应用于此类材料的无损检测技术应按以下几类进行评估：在其开发的早期阶段检测、定位和识别损坏的有效性，应用的复杂性和检查的成本。在下面的研究中，作者对三种复合材料结构进行了实验测试，这三种复合材料结构由玻璃纤维增强塑料、具有由相同材料制成的芯部和由铝合金制成的面板的混合复合材料以及从军用飞机的垂直稳定器中提取的碳纤维增强塑料结构制成，几乎没有可见的冲击损伤和分层。使用各种技术进行测试，包括PZT传感;超声波，热成像和基于振动的检测，以分析这些方法在飞机元件检测环境条件下的适用性。所进行的分析可以得出结论的有效性的应用方法和它们的具体应用在复合材料元件的无损检测。(C)2015爱思唯尔有限公司版权所有。
The application of polymeric composites as materials for structural design of vehicles and other constructions has led to maintain them in safe and effective manner. A special attention should be paid to the aircraft structures, which must be lightweight and reveal superior mechanical properties in order to fulfill growing demands in this industry. Thus, the non-destructive testing techniques applied for such materials should be evaluated in several categories: effectiveness in detection, localization and identification of damage in possible early phase of their development, complexity of application and a cost of inspection. In the following study the authors experimentally tested three composite structures made of glass fiber-reinforced plastic, hybrid composite with a core made of the same material and face sheets made of aluminum alloy and a carbon fiber-reinforced plastic structure extracted from the vertical stabilizer of a military aircraft with barely visible impact damage and delaminations. The tests were performed using various techniques including PZT sensing; ultrasonic, thermography and vibration-based inspection in order to analyze the applicability of these methods in the environmental conditions of inspection of aircraft elements. The performed analysis allows concluding about effectiveness of the applied methods and their specific applications in non-destructive testing of composite elements. (C) 2015 Elsevier Ltd.
