Introduction In recent years, the demands for new materials with excellent comprehensive properties become stronger and stronger[1−2].
The large grain sizes is bad for materials mechanical properties, by the contrast the small grain sizes can improve materials mechanical properties.
Preferred orientation affect materials mechanical properties.

Black bamboo, a kind of new green materials, has the potential of being made into furniture and the Huxiang Culture which is rich in human and unique in its own region.Aim:The combination of these two can create new furniture.
Black bamboo raw materials are bamboo, fast growth, it is recognized as environmentally friendly human timber.
This article combines black bamboo materials and Hunan cultural elements together, not only can enrich the furniture style, but also can make furniture with rich cultural connotation and unique geographical features.

The cerium dioxide films were prepared with cerium foils as raw materials by anodization in Na2C2O4-NH3∙H2O-H2O-(CH2OH)2 electrolyte.
If the porous cerium dioxide film is prepared with cerium foils as raw materials, we may solve the above problems.

Therefore, two different materials are used.
Both materials have been already tested separately against ballistic and blast threats [2].
In this work, we present tests with a composite protection made of these two materials against a ballistic threat.
As discussed in the experimental section, the friction between the different materials is important.
