纤维增强聚合物复合材料因其独特性以及定制特定性能以满足必要要求的能力而被用于许多应用。与许多其他材料一样，复合材料容易出现缺陷，这可能会显着降低其物理性能。因此，纤维增强聚合物复合材料应在零件使用之前和使用寿命期间进行测试，以确保不存在缺陷，或缺陷的严重程度不足以损害材料的完整性和性能。然而，由于复合材料的非均质结构以及制造过程中使用的材料种类繁多，因此对无损检测提出了独特的挑战。本研究涉及使用电容电桥对玻璃纤维增强复合材料进行无损检测。使用这种方法的主要优点是我们可以同时确定复合材料制造和使用过程中可能出现的空隙、裂纹和吸湿性。版权所有 © 2009 ASME
Fiber reinforced polymeric composites are used in many applications due to their uniqueness, and the ability to tailor specific properties to satisfy necessary requirements. Like many other materials, composites are susceptible to defects, which may significantly degrade their physical properties. Hence, fiber-reinforced polymeric composites should be tested both prior and during the life of the part to ensure that defects are either not present, or are not severe enough to compromise the integrity and performance of the materials. Composites, however, present a unique challenge to non-destructive testing because of their non-homogenous structure, and the wide variety of materials that are used in the manufacturing process. This study deals with the non-destructive testing of glass fiber reinforced composite materials using a capacitance bridge. The major advantage of using this method is that we can simultaneously determine voids, cracks and moisture uptake, which may occur during manufacturing and the usage of the composites.Copyright © 2009 by ASME
