Three coating materials are investigated: DLC, CrN and Al2O3.
Besides, the crack growth criteria for ductile materials are not well developed yet.
In general, there are four models of materials’ fracture toughness based on the material thickness and the fracture mode.

Introduction Nowadays composite materials have been widely used in many industries, such as aerospace, automobile, civil, sports, et. al..
Sisal fiber, as one kind of natural fibers which have been interestingly studied, has also caused a lot of attentions in materials scientists and engineers and was selected in this research [4-6].
Materials and Tests Sisal textiles were obtained from Guangxi province, China.

It is the major material of electronic packaging materials, radiator, piezoelectric element and reinforcing and modifying agent of the composite, etc. [1].
Though some synthesis can lower reaction temperature even react at room temperature [6], but can't get pure hexagonal AlN, besides the raw materials are very expensive.

Introduction Over the last few years, a number of researchers have been involved in investigate the exploitation of natural fibres as a load bearing constituents in composite materials are increases.
The use of natural fibres materials in composites has increased due to their relative cheapness, their ability to recycle and for the fact that they can compete well in terms of strength per weight materials [1,2].
Methodology Raw Materials.

By using the data of drilling and logging and other materials, the contour graph of the thickness of the remnant strata can be worked out.
So it is necessary to select the best method to restore the thickness of the denuded strata based on the characteristics of different basins and the quality of materials.

During our laboratory experiments the aptitude of cold rolling of joints and their environment, as well as the change in the features of materials was analyzed.
Welds properties were tested by rolling in VON ROLL rolling mill (Fig. 1) at the Institute of Materials Science - University of Miskolc.
The examined materials were laser beam welded before test rolling.
