Environmental Factors on Aging of Nitrile Butadiene Rubber (NBR) - A Review Tang Qingyuna, Zhang Weifangb Science & Technology Laboratory on Reliability & Environment Engineering, Beihang University, Beijing, China atangqingyunene@163.com, b08590@buaa.edu.cn Keywords: NBR, aging, environmental factors, mechanical property, coupling Abstract.
The emphasis of present works is test of physical and mechanical properties of NBR, and the micro analysis should gain special attention.
However, these properties are not good indicators for seal performance.
Zhao [1] studied the change of mechanical properties and chemical structure of NBR subjected to thermo-oxidative aging, and discovered a good correspondence between them.
Mechanical stress can affect the speed ratio of two processes: degradation and structuration of polymer, and reset the chemical bond inside it.

The reason for this is that the mechanical properties in the base material are usually used in the structural analyses in the welded structure considering a proper safety (or reduction) factor in the weld.
Weld mechanical properties of Alloy800HT.
Weld mechanical properties of Alloy617.
Consequently, the normalizing factors in each region are summarized in Tables II-IV for Alloy800HT, SUS316L, and Allo617 weld strap, respectively.
According to Tables II-IV, the mechanical properties in the weld and base material are different to some extent, and thus might affect the structural behavior of the welded components.

This study mainly analyzed the factors that affected the mechanical properties of laminated veneer lumber（LVL）.
To increase the mechanical properties, metal mesh was inserted into LVL that made of fast-growing timber.
Effects of different factors were evaluated on the mechanical properties of LVL, several enhancement modes of metal mesh were designed to reinforce the LVL.
Then, the mechanical properties (modulus of rupture and modulus of elasticity) of the LVL specimens were measured by static bending test.
This orthogonal experiment was conducted to show the effects of factors on the mechanical properties (MOR and MOE) of LVL, including the type of metal mesh, the mesh number of metal mesh, the position of metal mesh and the angle of metal mesh-wood grain.

Mechanical properties of the calcium-plastic composite have a great influence on the containers.
The main factors affecting the mechanical properties are the process and material formulations.
Under the usage of analysis of variance on single factor experiment, the mechanical properties of the calcium carbonate-plastic composite with three different coupling agents (silane, titanate and aluminate) were studied in the same test conditions.
The results show that: The type and quantity of the coupling agent effect a lot on the mechanical properties of the composite.
It clearly demonstrated that silane coupling agent has the greatest effect on mechanical properties of the composite.

A series of soil-structure shear tests was taken by self-made large single shear apparatus and the main factors affecting behavior of the interface are studied.
It was shown that the deformation and mechanical properties are determined by the roughness of structural surface, particle size distribution and normal stress.
As early as in 1961 foreign scholars Potyondy[1] used stress-controlled and strain-controlled direct shear apparatus to study the mechanical properties of the contact surfaces between a variety of soil material and structural surface, summed up four factors of the soil, moisture content, surface roughness, normal stress that affect the friction strength of the contact surface and raised the design method of the structural safety.
Clough etc.[2] studied the mechanical properties of the contact surface between the soil and the concrete by direct shear tests, the shear stress-strain of the the contact surface showed a hyperbolic relationship which is still used by people.
