Because of the characteristics of both one dimensional nanostructure and excellent physical and chemical properties, the kinds of novel nanomaterials -tungsten carbide nanowires, have important academic significance and practical meaning.
The rapid intrinsic growth characteristic of nanometer WC grain during sintering process lead nano-grained cemented carbides with excellent mechanical performances is not acquired [10].
Fig.1(f) shows SEM images of the materials synthesized at 1200 °C starting from a mechanical mixture of WO3 and CNTs.
The needles are not grown on a flat substrate but only on a substrate with a curvature, so the curve radius of the substrate is a key factor that affects the nucleation of the WC needle.

This led to be a weaker factor of cracking on those RC structures.
Theoretically, the factors affect the bond between the stressed rebar and concrete include chemical adhesion, friction forces and mechanical anchorage of the ribs against the concrete interface.
These factors can be implicated in three major subject headings: structural characteristics, rebar properties, and concrete properties.
Where the rebar properties usually include size/geometry, loading stress, yield strength, and surface condition [1,2].
Moreover, the typical quasi-static load- displacement curves may indicate the bonding properties of different rebars.

Some cases reported were due to mechanical jointing failure with improper screw insertion.
Unlike solid wood, wood based composites material failure and fracture properties are not getting the necessary attention by researcher.
The mechanical properties were determined initially and have met the Type P2 requirement based on European Standard EN 320 [9].
Mode 6 damages occurred due to two factors.
The presence of the failure would not affect the particleboard appearance.

The pre-ECAP mechanical properties were 232 MPa tensile strength, 65% elongation, and Vickers hardness of 63 (load: 2.9 N).
After eight ECAP passages, the properties changed to 438 MPa, 28%, and 141, respectively.
The fatigue specimens were electrolytically polished (approximately ≈ 25 mm from the surface layer) prior to mechanical testing to remove any preparation-affected surface layer.

Therefore, it is possible to enhance strength properties of creep resistant steels by precipitation hardening and stabilization of dislocation structure during creep.
Substructural changes are strongly affected by the plastic deformation during creep test.

The main research contents include four parts as follows. 1) Old asphalt pavement and traffic volume investigation Present pavement investigation data such as pavement and sub-grade structure, material, environmental factors and using condition etc can be obtained.
Design method mainly includes as follows: CBR and DCP method combined with other design method; deflection design method when firmly believing pavement destruction to be caused by roadbed defect; mechanical design method through computer program to imitate actual pavement is more reliable but complex compared with the design method based on experience.
Gradation design of cold recycled mixture still lacks experience; QC/QA on Cold in-place recycling is less effective than plant recycling; Cold in-place recycling construction is easily affected by climate conditions.

The development of new materials is to support the technology rapid development of one of the factors, make the material surface functionalization of compound, improve, and high strength of the innovation of the new material is research and development of the ing, lubrication, corrosion resistance, heat most looking forward to.
If metal organization toughness is insufficient easy generation surface layer under the action of shear stress cracks and peeling, influence of the composite material multi-layer anti-wear properties.

Such a flow directly cools the electrical and mechanical components or passes through an air/liquid heat exchanger, usually located on the top/back side of the nacelle.
In addition, in the former case, the airflow can carry a large amount of dust, sand, salt, etc. within the nacelle, whereas in the late case the heat exchanger affects the airflow around the turbine, thus making more difficult its control.
Such enhancement also depends on other factors, such as particles shape, volume fraction and thermal properties [7][8][9][10][11].

And this method does not affect the structure appearance after reinforcement.
This method is commonly used for concrete components which are not seriously damaged which can prevent steel which is in the cracks from corroding but can not restore the original mechanical properties of damaged components.
