For most common chemicals, the Carbon – graphite is inert, and has the self-lubrication function which is difficult to obtain in other sealing materials.
Not only service life has been prolonged, but also the leakage problem caused by sealing materials has been basically solved.

The drawbeads and the radius of the die introduce a complex bending-unbending loading history as the material passes through these regions.
The simplified assumptions on the law of material behavior (theory of total plastic strain) and the action of the tools are used.
The process and material parameters can be found in Tab.1.

Introduction It is known that some distance away from thermodynamic equilibrium, a few new, at times unique physical and mechanical properties of materials are found [1].
In general, experimental investigations into the effect of dynamic non-equilibrium processes (DNPs) on the mechanical behaviour of various structural materials are of particular importance [3–5].
These newly formed dissipative structures account for a noticeable variation in the initial mechanical properties of materials under further static and cyclic deformation [6].

Introduction Wood materials are a plural system.
Due to its excellent compatibility, it can be used to make homogeneous materials.
The wood materials still retain the linear and regular permutation.
The reason is that the woody materials retain the stereo-chemical structure of macromolecular chains.

The Influence of Plastic Deformation Performed before and after Electron Beam Irradiation on the Morphology and Structural Properties of UHMWPE Joanna MASZYBROCKA1, a *, Adrian BARYLSKI2, band Jerzy CYBO3, c 1, 2, 3Institute of Materials Science, Faculty of Computer Science and Materials Science, University of Silesia, 75 Pulku Piechoty 1A, PL-41-500 Chorzow, Poland ajoanna.maszybrocka@us.edu.pl, badrian.barylski@us.edu.pl, cjerzy.cybo@us.edu.pl Keywords: crosslinking density, degree of crystallinity, electron beam irradiation, lamellar structure, UHMWPE.
The tests were conducted on the specimens of the initial materials irradiated with an electron beam (N20.i, NO50.i), deformed before irradiation (ON20.i, ON50.i) and deformed after irradiation (NO20.i; NO50.i).
The examined materials were etched at room temperature for approximately 2 hours.
When analysing crystallinity degree Xc as a function of a growing radiation dose for materials processed according to ON and NO variants (Fig. 1), it can be noted that for a small deformation of ef ≈ 0.2, an insignificant reduction in Xc appears when compared to the material subjected to N radiation crosslinking only.
Changes in the orientation of the lamellar structure as a result of the applied technological variants on forming materials: GUR1020 –a) and GUR 1050 –b) Fig. 4.
