This treatment method showed a better effect on improving mechanical properties in comparison to NaOH-treated of bagasse fiber-polyester composites [4].
In this study, we have tried to evaluate water absorption and tensile properties of their composites.
Tensile Properties of Composites.
The trend of composites tensile properties has a little difference with their single fibers [6].
These may be due to the reinforcing ability of the fibers not just depending upon the mechanical strength of the fibers but some factors affect the interfacial interaction between the matrix and the fibers surface like polarity of the fiber, surface characteristics and the presence of reactive centers of functional groups [13,14].

The fundamental component of machined PcBN cutting tool affected layer was obtained and the reason of begetting affected layer was analyzed.
Ko-Ta Chiang in his paper told us that the main two significant factors on the value of the material removal rate (MRR) were the discharge current and the duty factor.
To a certain extent, the existence of surface affected layer has affected the service life of cutting tool, and has became the second important elements that affected cutting tool life besides the geometry size factor.
The workpiece material and technological parameter of electrical discharge machining influence the affected layer thickness and its physical mechanical property.
The WC, WN and TiO are showed in the affected layer

Three factors are constituted for this.

The effect of sheet and material properties on springback in air bending G.
Process geometry and material properties affect the outcome, therefore, full knowledge of these values is critical.
Among the main factors affecting bending results, actual sheet thickness was regarded as a mayor one.
Table 2 - Material properties.
All materials showed different mechanical properties along the rolling direction and transverse to it.

Mechanical properties under dynamic tensile loads were determined.
Mechanical properties of these steels depend on a strain rate.
That is why it is important to determine, how high deformation rates affect the mechanical properties of medium manganese steels.
Change of mechanical properties for different deformation rates.
These factors may have opposite effects on the mechanical properties, which further increases the complexity of the analysis.

How to obtain favorable mechanical properties, thermal properties and electrical conductivity seems especially important.
In these thermal properties, thermal conductivity is one of the important factors.
The results show that the particle size of carbon black affects some of the mechanical properties of carbon black-filled nature rubber.
From the table 2, The mechanical properties of carbon black- filled nature rubber are: Shore A hardness 54～75degrees ,elongation at break 490.6%～781.3% and 300% modulus 4.6～17.12MPa.
(2)Particle size and the structure of carbon black also affect the mechanical properties of carbon black-filled nature rubber, the smaller carbon black Particle size and the higher structure of carbon black could improve tensile strength more.

In high speed state, deformation of head face caused by the temperature rise of end face is the key factor which constraints the stability of mechanical seal.

The limited mechanical resistivity together with the high total open porosity could be highlighted as the dominant factors affecting the durability of the researched historical masonry.

The two materials are bond together to offer better mechanical properties.
Thermal damage is a direct consequence of the large difference in thermal properties of the carbon fiber and the polymer matrix [3].
The heat-affected zone (HAZ) is the area of base material, which has had its microstructure and properties altered by heat intensive cutting operations.
Factors that affecting the HAZ are pulse energy and pulse repetition rate.
Which means both of these factors interrelated, when a value is changed, then the response will also change.

In this regard, the need to identify fundamental factors affecting both the thermophysical and strength characteristics of the material is of interest, as it will determine the ways to control the lightweight concrete quality.
Thus, the common factors, affecting which it is possible to simultaneously change the heat engineering and strength characteristics of lightweight concrete in the right direction, thereby increasing the efficiency of products and structures, have been identified.
At the first stage of research, the common technological factors that affect both the strength and thermophysical characteristics of concrete were identified.
The influence analysis of the main variable factors on the corresponding indicators of concrete properties was carried out on the basis of the obtained regression equations with the graphic models’ construction.
Thus, the studies of lightweight concrete based on microspheres showed that a change in the basic properties of a given concrete from prescription and technological factors obeys the laws generally accepted in concrete technology.
