It is believed that the use of this material to form composites is able to enhance the mechanical, thermal and electrical properties of Polyurethane (PU), Polyester (PE) and Epoxy.
In spite of the fact that aforementioned methods were used to produce better dispersion nanoclay/polymer composites, and enhance the bonding between the nanoclay platelets and surrounding matrix through the reduction of viscosity of the resin by increasing the temperauture at the early stage, some procedures that may seriously affect the properties of resultant composites.
Conditions of all samples for the test Materials and Mechanical Properties To investigate the homogeneity of all the samples subjected to different manufacturing processes, fractographic observation through the use of Scanning Electron Microscopy (SEM) was conducted.
The results are agreed with our previous study that the mechanical and material properties of nanoclay/epoxy composites would drop if the amount of nanoclay excesses their optimal value.

The experimental results show that the Taguchi method of thermal mechanisms in this study of the four control factors affecting the order: k value of thermal compound > fan power > liquid type > pump flow rate, and to identify the best combination of factor levels.
The structure consists of a conventional mechanical pump, liquid, cold plate, parallel plate and fan.
Selected properties with high thermal conductivity materials for fabrication cold plate cooling plate may be to lower the internal structure of the conduction thermal resistance effect.
From Table I of the S / N response data, we know that the best combination of factors and levels are A3, B3, C2 and D3.
Finally, using Taguchi analysis , then find the best heat dissipation level of four control factors.

Mechanical Properties of Films.
Mechanical properties of HPMC/Sh Composite Films with the various emulsifiers.
Hence, the films had poor mechanical properties [4, 18, 19].
Therefore, it enhances the mechanical properties of the composite films [20].
In addition, the particle size is also one of the factors affecting the viscosity of emulsions.

Additionally, there was less than 3% observed variation in the three-way tensile properties. 1.
The process was found to be capable of producing rings with distinct mechanical properties but the same final geometry [8] .
The head forgings underwent mechanical property testing and organizational assessment. 2.
When comparing the size of the F-value of each factor with each other, it can be known that the order of significance of the factors affecting the stability of the head-forming process is as follows: λ1 (under pressing speed) > λ4 (deformation temperature) > λ2 (rotational speed of the lower mold) > λ3 (inclination of the upper mold).
Among the factors affecting the stability of head formation, the quadratic terms λ12、λ22、λ32 and λ42 all manifest extremely significant, but the intersection factor between the two factors manifests non-significant.

The effect of PTFE on the mechanical and friction and wear properties of GF/PA6 composites Jian.
It is getting more clearly that additional PTFE additives in matrix could improve matrix-dominating mechanical properties.
However, when the concentration of a PTFE is above the saturation level, only a part of the molecules locates in the interfacial area and the excess is dispersed in the matrix affecting its homogeneity and consequently the mechanical properties of the composite.
Conclusions (1)The mechanical properties of PA6 composite increased with the addition of GF.
And the addition of PTFE further improves the mechanical properties of GF/PA6 composite.

There are some factors that can affect the experimental result of sandglass extrusion.
Among these factors, free space in mould cavity is very important, which can affect the forming of the fold during the extrusion.
There are some factors that can affect the experimental result of SE, such as extrusion ratio, extrusion times, extrusion temperature, friction and free space in mould cavity etc.
These factors have different effects on material microstructure, properties and defects.
Among these factors, free space in mould cavity is very important which can affect the forming of the fold.

Compared with the heat cured samples, the mechanical properties and infrared structure of the samples cured by microwave is constant.
At present, the major factors that restrict the development of SiO2/UPR composite material are mass stability and high cost.
However, there are so many factors that effect the quality of SiO2/UPR composite material, take raw material, equipment and process for example, curing as molding link that has vitally important effects on tincture and mechanical property of products[3].
