The researcher has focused upon considering types of mould materials, because they need efficiency properties.
However, the cause probably resulted from mechanical properties of the plastic mould steels, and created better quality than plastic mould steel AISI-1050, based on the testing completed in such conditions [6,7,9].
Wear Analysis of End Mill From the result of the analysis of the surface quality obtained from the milling process (machining milling) using an end mill of 2 cutting edges (twin flute), it has been found that the factors which affect the quality of the milled surface are speed, feed rate and depth of cut, which were the factors in the study.

Some of the factors should be consider which are; the temperature to expand the graphite material, the sonication time and also the type and ratio of modification material used.

Tear propagation is the typical fracture mode of fabric laminates, which is affected by stress and damage shape (size).In this paper, envelope material which is mainly composed of fabric laminates used in stratospheric airship is the objective of the study.The tear propagation and tearstrength of Cross-shaped specimens with initial damage whichwere in different situations (size, angle and shape) were studied through biaxial tensile test which was conducted in a tailor-made testing machine, and the strength is noted simultaneously to gain the mechanical properties of the specimens.
The mechanical property of the envelope material which is commonly used as the major structural material, directly affect the floating height, effective load, sustained flight time and the service life [1].

Introduction Temperature is one of the main factors affects the mechanical properties of rock.
These cases must take into account the thermo-physical and mechanical properties of rocks at high temperatures.
Houper[1] inspected some mechanical properties of the granite under different heat treatment temperatures.
Ferrero and Marini[2] performed destructive tests on two kinds of marble under different temperatures, analysized the changes of porosity in different temperatures, and pointed out that the crack density is the main factor affecting the marble cracking.
With the curves of mechanical properties of granite at high temperature through trial, Xu[4] pointed out that the compressive strength reduced as the temperature increased, and the Poisson's ratio was affected by temperature.

However, this significantly compromises mechanical strength, leading to gaps and deterioration of material properties (breathing resistance, dustiness, etc.).
The authors tested this material for mechanical, physical, and biophysical properties, confirming its high capture efficiency and thus recommending it for respirator manufacturing.
According to the authors, this will improve the mechanical properties of the polypropylene material and simplify the process of manufacturing filtration respirators.
