However their works concentrate on structural stiffness of wing structure on different wing materials and techniques to determine flutter.
Discussion From the tensile test conducted on the flat plate composite wing, the specimen possessed the behaviors of composite materials since there is no indication of plastic region in Fig. 8.
The material mechanical properties are as shown in Table 1.

The UVM is highly applied to machining nonconductor materials, hard & brittle materials such as various ceramics etc, compare with Electrical discharge machining (EDM), electrolysis machining and laser machining, UVM is independent on the conductive of materials and no thermo physical activity on part, compare with the photo etching, UVM can machine the large depth-to-width ratio on part.
All these properties are making the UVM the unparallel advantage in cutting hard & brittle materials.
These results provide a theoretical basis for machining monocrystal materials such as SiC, Si etc, also obtain reference for efficient processing and a good surface quality of these precious materials.

The surface properties of wood-plastic composite materials have been found to be similar to those of polyolefin materials, thereby presenting a challenge to the use of adhesive joining methods.
Plasma chemistry can be performed to improve the adhesive properties of polyolefin materials.
