Experimental Materials.
As has been discussed before, wood fibers and HDPE are two kinds of materials with different physical properties and microstructures.
Through surface treatment of wood fiber may improve the interfacial bonding between these two materials to a certain degree.

For steel thixoforming, and generally for high melting point materials, the high semi-solid state temperature induced difficulties linked to tools materials.
These difficulties do not exist with low melting point materials.
For high melting point materials, thermal phenomena become important and their control is essential.

With the decrease of material dimensions and structure size, the semiconductor nanomaterials have more excellent features than the bulk materials in electronic and optical properties, such as belt edge blue shift (slightly blue shifted by ~30meV to bulk InAs on 20K) indicating the radial quantum confinement effects, which makes it possible to research the structure of the nano laser[1,2].Theoretically, by controlling the size and morphology of InAs nanomaterials can achieve emission wavelength is continuously adjustable from blue-ray to 3500nm, and reparation of single-electron transistors [3] resonant tunneling diodes [4] and ballistic transistors [5].In bulk form, III-V materials occur in either the zincblende (ZB) or wurtzite (WZ) crystal structure due to the energy difference between the two phases is small, however, when the dimensions of the system are reduced, the twin defects, stacking faults, and ZB-WZ polytypism are commonly reported problems [6,7].

Research shows that when ceramic materials are replaced by nano- materials, the mechanical properties of materials can be greatly improved, mainly in the following three aspects: 1) the breaking strength is greatly improved; 2) the fracture toughness is greatly increased; 3) the heat resistance is greatly improved.
The application of nano materials to anticorrosion coating greatly improves the anti-corrosion coatings and open up new ways to anti-corrosion coating and new areas of application of nano-materials.It is a major innovation of anti-corrosion coating.
