Rubber adhesive bonding structures have been applied increasingly in aviation, aerospace, machine and chemical industrial areas because of their unique properties - including sound absorption, damping, airproof, insulation, thermal barrier, etc. Rubber-composite bonding structures are the important new ones of rubber-nonmetal adhesive structures. They are rather sensitive to deviation of manufacturing technology parameters and tiny change(s) of environmental condition(s) during bonding process partly owing to the remarkable different physical and chemical properties of rubber and composite materials. Therefore, non-destructive testing and evaluation (NDT&E) are become a focal problem for rubber bonding structures in industrial applications. The theoretic estimation results show that its sensitivity is dependent on surface deformation change of the object to be tested. Interferometric intensity coefficient will change dramatically when the surface deformation is up to 0.1 lambda. Experimental and practical testing results have demonstrated that disbonding with diameter 10 mm and voids with diameter 3-5 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.
