Introduction
Kevlar-Zirconia-Epoxy composites can be utilized in applications that need high-wear resistance due to their exceptional mechanical properties, low friction, and high durability.
Conclusion The wear mechanisms of composite coatings vary significantly under dry and lubricated conditions, influenced by operational factors like contact loads and rotational speeds.

Thus, comparison of the in-plane static mechanical properties of two kinds of composites at room temperature was carried and the related standards were also listed in table1.The stiffness of 0° tension, 0° compression and flexure property of T800/5228E were decreased, but other mechanical properties like 90° tension, 90° compression and in-plane shear stiffeness and main strength characterization were not affected or even gained some improvement.
The mechanical properties of composite laminate depends on its constructure.
How it influences the CAI and other mechanical properties is an interest work to be done.

JMatPro software is used to predict the mechanical properties of steel alloys.
Some mechanical properties like wear resistance of alloys might be controlled by the volume fraction of eutectic carbides, microstructure, orientation, and matrix properties.
The observed effects of detrimental phases (Sigma, M23C6, G-phase) on SUS304 toughness and ductility Sigma(σ) precipitate is an essential phase in several stainless steels, one of the main factors for mechanical properties, corrosion resistance, weldability, and hardness [16].
Interfacial energy and coarsening rate of carbides are essential factors to control toughness for steel alloys.

The influence of the morphological features of the particles of the initial powder on the grain size and the mechanical properties of the sintered compact is determined.
Therefore, an important factor affecting the emission capacity and durability of the cathode is the properly formed structure of both the surface and the emitter body [7].
It is an important technological characteristic of the powder affecting the structure of the powder compact (Table 1).
Measurement of the mechanical properties of the samples was carried out by two methods: the method of restored imprint and the method of measuring indentation.
Conducting tests by the method of measuring indentation allows obtaining additional information about the mechanical properties of the surface layers of the material.

Introduction
Chemical-Mechanical Polishing (CMP) is a process of combining with chemical and mechanical reaction.
Based on the common polishing pad material types, material properties and surface structure in CMP process, Xiong Wei summed up the influences of polishing pads to the CMP process[5].
Phyllotactic pattern acquires with special geometry, physical and chemical properties of biological structure arrangements, which have been obtained by the biological evolution and natural selection.
These are very important factors for improving the polishing ability of the polishing pad.
In Fig.2, choosing the material of the based pad of the polishing pad is mainly based on the requirement of the mechanical and electrochemical properties of materials.

Several SMA devices are based on their unique properties.
Even though they possess high damping and attractive shape memory properties they are difficult to produce and process and are also more expensive.
DMA is a technique that can be used to obtain a lot of information pertaining to the damping/mechanical properties of any viscoelastic material.
Other factors which influence the strain recovery by SME are the imperfections in the material, such as quenched-in vacancies, dislocations, etc., which cause the pinning of martensite plates, and thereby hampering the transformation which, in turn, decreases the strain recovery.

For increase cutting tool durability is necessary maximally possible elimination of these factors.
All these factors of cutting tools are the only consequence of these cutting tools durability.
Cutting tool durability determines its cutting properties and machinability [2, 6].
Material for workpiece is from specific material list with guaranteed chemical structure and mechanical properties, see Tables 1 and 2.
The manufacturing process is affected by a large number of factors which are in the testing laboratories optimized and do not operate on a given process and therefore do not affect the results of such experiments are compared with the practice of heavily distorted.

The liquid spreading speed in the textile material would affect the comfort property.
Thus, the liquid spreading speed of the material would affect its comfort property.
The properties of foam are governed mainly by the selection of raw materials (e.g. composition and properties of the raw materials) as well as the manufacturing process(es) [12].
