Investigation for Test Sensitivity of Shearography


Article Preview

To reduce weight and improve strength in the aerospace industry, composite structure connected by glue has gained popularity as a replacement for conventional materials and structures. However, the adhesive bonding process is more susceptible to quality variations during manufacturing than traditional joining methods. The integrality, strength and rigidity of product would be broken by disbonding. Investigate the sensitivity and accuracy of the testing method was more impotent to ensure the product quality and testing efficiency. This paper presents a study of detecting sensitivity of sheargoraphy methods when it is used for inspecting disbondinging on honeycomb structures. The potential of shearography method is also outlined.
