This paper designed Poplar LVL production experiments under different process conditions, and measured the mechanical properties of poplar LVL specimens under different experimental conditions.
The results showed that, it is feasible that grey theory is used to analyze the influence level of production technology of poplar LVL on the mechanical properties.
Investigations show that, mechanical properties and engineering performance of LVL are affected by many factors such as wood species, veneer thickness and quality, processing variables, member size, in service environment and loading types [1-5].Different factors have different influence levels on the mechanical properties.
So it is feasible that grey relational analysis is used to analyze the influence level of production technology of poplar LVL on the mechanical properties.
This paper only had grey relational analysis of the influence level of four factors on the dynamic shear modulus, the grey relational analysis of the influence level of other factors on the other mechanical properties remain further study.

Crystallization and Mechanical Properties of Nano ZnO/PP/PLA Composite Filaments 1 YingChen Zhang1,2,3, JianFei Xie 2, HongYan Wu3 ,Y.P.
The incorporation of nano-materials has proved that it is a very effective way of improving the mechanical properties, particularly the tensile strength of PP (polypropylene)/PLA (polylactic acid) composites.
It is regarded as an environmentally friendly process since no chemicals are involved and also as an effective way to modify the bondability and wettability of polymer surface by introducing polar groups or increasing surface roughness without affecting the bulk properties [5].
Compared with the Figs, the uneven dispersion of the samples may cause the relatively lower tensile properties.
On the other hand, it is clear that PLA is well-dispersed on the polymer matrix for sample 6 which confirmed its outstanding tensile properties (Fig.2 (c)).

Length and diameter of basalt fiber both influence the mechanical properties.
The basalt fiber content is the single factor for each, and the research on mechanical properties of basalt fiber reinforced RPC is by changing the fiber content.
Test results and analysis Static mechanical properties.
As to the static mechanical properties and flexural impact properties, basalt fiber improve flexural impact properties is much more significant than improving static mechanical properties of RPC, which illustrates that the main role of basalt fiber is to improve the toughness of constructional element by absorbing impact energy.

The Impact Evaluation of Factors on the Adhesion of Modified Polytetrafluoroethylene Films in a Glow Discharge Non-Thermal Plasma M.A.
However, after modification, the polymer film changes its physical properties, becomes brittle, changes the transparency of the film.
Based on the data obtained, a mathematical model of the dependence of the change in the contact properties of the resultant feature (wetting angle) of the PTFE film on the factor values of which are: voltage (x1) and discharge current (x2) in the reaction chamber.
According to the data obtained, a matrix of experimental planning of the wetting angle depends on 2 factors: amperage (I) and voltage (U) (table. 2).

It is found that mechanical properties of composites increase with the increasing particle size of iron.
Specific reasons in the following two aspects: on the one hand, the ratio of powder particle size of the matrix is an important factor of effecting reinforcement distribution uniformity and the final material properties.
The reasons are that enhanced particle size and the degree of distribution is an important factor affecting the performance of the composites when composite volume ratio is same.
Summary （1） It is found that mechanical properties of composites increase with increasing particle size of iron power.
The reason is believed that big particle size of the iron powder contributes better effect on dispersion of reinforcing particles in the composite to result in better mechanical properties

The objective of present work is to study the influence of cooling rate and quenching temperature on the mechanical properties of ferrite-bainite steel and to establish the correlation between them.
Considering the above factors, the overall number of high angle grain boundary appears increasing after the first.
Mechanical properties.
The mechanical properties of rolling steel are shown in Table.1.

The microstructures as well as the effect of starting powders size on the mechanical properties and thermal fatigue properties were investigated.
The mechanical properties and thermal fatigue resistance vary with the addition of α–Si3N4 powders.
In Hasselman’ theory, some parameters are introduced to evaluate resistance of crack initiation and propagation, and the fracture strength is one of the most important factors[3].
Research has highlighted that the final properties of nano- or ultra-fine non–oxide ceramics are strongly affected by the characteristics of the staring powder [6,7].
The addition of α-Si3N4 powders affect the mechanical properties, and the maximum value are obtained when the amount of α–Si3N4 powders is 40wt

By decrease of the observed properties of the stored wood, a deterioration a quality of produced pulp can be expected (a higher Kappa number, amount reject and decrease the mechanical properties of pulp).
Oak belongs to ring-porous wood species whose mechanical properties increase if an annual growth is higher [3].
Lower annual growth can influence moderate decrease of mechanical properties.
Based upon the decrease of mechanical properties with the time of wood storage, it is also possible to expect decrease of mechanical properties of pulps prepared from the stored wood.
After some time, wood is affected by wood decaying fungi, which gradually degrade wood, and thus properties of wood change.
