Diameter has an important role in determining mechanical, electrical, optical and biomedical properties of fibers [4].
Several parameters affect physicochemical properties of electrospun nanofibers.
But our results showed that flow rate is not affecting the size notably, which is probably a result of both mechanisms mentioned above.

It was found that the addition of a melt viscosity modifier to a carbon-filled composite helps to maintain the linear dimensions of the fiber filler particles, thereby increasing the physical and mechanical properties of the material.
The physical and mechanical properties of such materials are much lower, due to the limited length of the fibers, on which the properties of the material directly depend, as well as the impossibility of regulating their orientation in the polymer matrix during production.
Considering the above, the study of the mechanisms and conditions affecting the change and preservation of the length of carbon fibers in reinforced composites is an important area.
Despite the slight difference, this difference significantly affects the properties of the material.
Increasing or maintaining higher values of the residual length of CF in the composite had a positive effect on the physical and mechanical properties of the composites.

The mechanical properties of aluminium alloy can also be greatly improved by thermomechanical processing.
Therefore, the most reasonable way is to increase conductor’s highest permitted temperature.As a result of all the above factors combined, we developed high strength and heat resistance aluminium alloy 6Z63.

The results show the key factors that affect the result of these assessment methods.
Key factors, which affect the result of the flaw assessment, have been studied.
In this part, the key factors which affect the analysis results of API 1104 and BS7910 have been extensively studied.
So it could be conservative for using the tensile properties of parent steel as that of welds.
BS7910 level1 and API1104 level 2 show lower conservative, but need more dates and material properties.

Conclusions (1) There are many factors affecting the accuracy of injection molded plastic parts and the relationship among the factors is very complex.
Besides, the property of the molding material, injecting machine and the process parameters also play a very important role.

Introduction With the rapid development of the logistics industry, multi-axis overloadinged vehicles has significantly increased, while it posed a serious effcet on the mechanical properties of the asphalt pavement[1-3].
Asphalt pavements are subjected to a variety of loading conditions increasing in both magnitude and quantity over the years, which are the principle factors contributing to a premature stress related failures before the life span of the mixture[5-6].
Since asphaltic-pavement is a complex structure consisting of a number of materials with different properties, perfect mathematical description of the structure may not be possible.

Mathematics Principle of Fuzzy Comprehensive Discrimination The method of comprehensive discrimination combines variety of affecting factors for evaluating the objects.
The steps are as follow: Establish factors set.
Factor set is composed of various factors of affecting the evaluation object.
The purpose of the fuzzy comprehensive evaluation is for getting appropriate evaluation result, based on the comprehensive consideration all the affect factors, from the evaluation set.
To reflect the importance of various factors, the various factors that ui should be given a corresponding weight wi.

Several piezoelectric properties were also affected by the heat treatment.
Electromechnical coupling coefficients of heat-treated LNN became about two thirds of those before the heat treatment, and mechanical quality factors became about six times larger.
Table I shows piezoelectric properties of LNN ceramics before and after the heat treatment, and PZT_Fe.

Several attempts have been conducted to improve the mechanical properties of mineral trioxide aggregate (MTA), including the addition of various nanoparticle materials such as silver and titania.
One of the main problems in synthesizing MTA from natural materials is its mechanical properties, particularly the low tensile strength.
The mechanical properties of MTA are influenced by several factors like water to powder ratio, liquid or solid type, mixing and placement techniques, compaction pressure, and temperature [6], [7].
Nevertheless, the study of nanoparticle’s addition to the mechanical properties of cement-like MTA prepared from natural materials has not been reported.
The effect of AgNP and TiO2 addition on other mechanical properties of cement-like MTA would be interesting to investigate.
