Evaluation of Rubber - Composites Bonding Components by Using Laser Electronic Shearography

摘要：

Laser electronic shearography is a fast, remote and global nondestructive testing and evaluation (NDT&E) method. The theoretic estimation results show that its sensitivity is dependent on surface deformation change 2 , 1 ▽δi1,2 of the object to be tested. Interferometric intensity coefficient ) ( 2 , 1 Ψ▽δi1,2 will change dramatically when 2 , 1 ▽δi1,2 is up to 0.1 λ. Experimental and practical testing results have demonstrated that disbonding with Φ10 mm and voids with Φ3 Φ5 mm in rubber-composite adhesive bonding interface can be found clearly and reliably by the method. A series of results including 2D, 3D images, have been presented in this paper.
