Introduction
Mechanical properties of fiber-reinforced plastics (FRP) are strongly dependent on a control of the
adhesion between the matrix and fiber.
The coefficients A and B are functions of the elastic and plastic properties of the constituents given by Okabe and Takeda [5].
The coefficients 1β and 2β are functions of the elastic and plastic properties and the geometric factors of the constituents given by Okabe and Takeda [5].
The mechanical properties of the fiber and matrix are listed in Table 1.

Introduction
Pervaporation membrane is of crucial importance for successful pervaporation separation technologies, and it could directly affect solution separation effect and equipment investment.
The PIC membrane displays excellent mechanical properties, and its permeability for water, and other water-soluble small molecule solutes is high, so it has been regarded as a promising membrane and becomes one of the research focuses.
However, the preparation process of membrane is complicated and obtained membrane is not homogeneous, which affects separation efficiency directly[5].
These properties will overcome the deficiency of PIC membrane.
It is noticed that the value of separation factor and permeate flux of PVAMC membrane increased obviously compared to QACPVA/CMAPVA, and the PVAMC membranes had the high temperature resisance property.

One of the intrinsic HPDL (High Power Diode Laser) properties is the rectangular beam shape, which can be profitably used in welding of large polymer parts.
Beyond reduced handling costs, the residual mechanical properties of the weld governed by the thermal cycle can be controlled by the pulse shape and are no longer constrained by the welding speed.
In determining the conditions of the process should take into account several important factors, including the following: the beam energy, absorption differences between the cast of aluminium alloys, laser scan rate.

f-the tension of each trunnion
k-application factor, because of acceleration ,repeated use and some uncertain factors, it takes k=1.2.
When hardware work in the hot environment, creep properties will change the mechanical properties of material greatly.
Because the temperature of iron ladle wall is about 350℃ in working field, so the trunnion area of iron ladle can’t occur high temperature creep, and the mechanical properties of material are almost invariant.
The stand or fall of the grid classification directly affect the computation precision and speed.
So, the safety factor n=3; the allowable stress.

Besides for thermo-physical properties of rubber, tires can performed as a high-quality heat sink and can be used an alternative construction material for tropical building to ensure the indoor comfortable thermal environment.
Accordingly, the main climatic factors affecting human comfort and relevant to construction are: air temperature, its difference between day and night, and between summer and winter.
It is observed that, for physical, mechanical and thermal properties of rubber (refer to Table-1), ELT can enhance heat sink and drain out the excess heat from indoor environment.
This has happened because ELTs are performing as a heat sink here because of their physical and thermal properties.
The main reason behind this reverse heat flow from the sand to the above ground floor slab is for the variation of physical and thermal properties of sand (refer to Table-1).
