The small addition of MWCNT and Cu into polymer have affected to improve mechanical properties of composites.
Increasing in mechanical strength of composites is strongly influenced by two factors such as good dispersion of carbon such as MWCNT and good compatibility between filler and polymer matrix.

Introduction Steel is recognized as one of the main factors in the development of the modern world.
The study will be performed by developing reliability based strength reduction factors.
Increasing percentage of carbon does lead to increase in strength however it does lead to a decrease in ductility and hardness while also affecting the weldability [2].
Carbon Equivalent (CE) Hardness, Strength, Weldability Needed to set cooling parameters for the thermos mechanical process and a small change in amount of carbon equivalent can affect the overall physical properties.

Effect of Pre-Treatment of Lignocellulosic Fiber on Mechanical Properties of Chitosan-filled Filter Media A.
The pre-treatment enhance the fibrous filter media properties, while filter media from untreated empty fruit bunch fibers showed lower mechanical properties.
Surface modification aims to tailor the surface characteristics of a fibre for a specific application without detrimentally affecting the bulk properties.
Results and Discussion Fiber-matrix adhesion is one of the crucial factors that affect the mechanical properties of the fibrous filter media.
Liu et al found that the low concentration of chitosan solution did not improve the mechanical properties of oxidized cotton fiber [6].

The two main factors affecting the values here: the first factor is the physical structure characteristics of human waist and hips.
The factor of fabric Clothing material has a direct or indirect contact with the human body, it plays a decisive role on influencing the comfort of clothing .The material of the clothing affects the comfort mainly on fiber structure of fabric and its properties, fabric structure, mechanical properties, surface properties, and the heat transfer performance.
While the factors of influencing comfort of trousers are not isolated, they are in an interrelated organic whole and they are interacted by each other.
We should improve comfort of the trousers considering various factors on the basis of knowing the factors of influencing the comfort well and make the trousers fit the human body better.

HSLA steels are designed to provide higher atmospheric corrosion resistance and improved mechanical properties than structural steels.
Due to excellent mechanical properties demand for HSLA steel is currently increasing.
The welding parameters play a significant role in welds quality, since they affect the microstructural and mechanical properties as well as the aspect, geometry and internal or surface imperfections of the welded joints [38].
The current paper presents the correlation between GMAW parameters and mechanical properties of hot-rolled HSLA steel butt joints.
Thus, the factorial experiments have four influence factors on two levels and three replicas included in the central point, according to table 6.
