Thermal damage is a direct consequence of the large difference in thermal properties of the carbon fiber and the polymer matrix.
The two materials are bond together to offer better mechanical properties [3].
Thermal damage is a direct consequence of the large difference in thermal properties of the carbon fiber and the polymer matrix [5].
The heat-affected zone (HAZ) is the area of base material, which has had its microstructure and properties altered by heat intensive cutting operations.
Factors that affecting the HAZ are pulse energy and pulse repetition rate.

Therefore, it could recognize that mechanical properties was improved by using low amount of nano-cellulose.
Furthermore, it has good mechanical properties and easily degrades by microorganisms in control conditions [5].
Moreover, plant fibers are also expected to improve the mechanical properties.

Mechanical Properties of Aluminium-Alumina Welding by Friction Welding Tummasook Mingmuang1,a, Sukangkana Lee.2,b and Chawalit Thinvongpituk3,c 1, 2 Department of Industrial Engineering.
The factors that affecting the friction welding process are often mentioned, there are five main variables include rotation speed, forge pressure, friction pressure, friction time and forge time.
These variables influence the properties of welding, especially in the metal to metal welding.
Thus, this research aims to study effect of feed rate on mechanical properties of welding interface.

The quality of the clinching joint is influenced by many factors, such as the material properties, die geometry, friction, and the state of the process.
The clinching joint can be affected by several factors, such as the tool geometry parameters and the process parameters.
The mechanical properties of the material were measured in University of Miskolc laboratories.

The key idea of this technology is to obtain components with optimized mechanical properties.
In fact, these process parameters affect the final microstructure and mechanical properties of the component.
The chemical and mechanical properties are listed in Table 1 and Table 2, respectively [18].
Effectiveness of process window for mechanical properties prediction has been verified.

In this study, it is showed that surface treatment affects adhesive strength and durability of aluminum/polycarbonate single-lap joints, and loading speed affects tensile-shear strength of adhesive joints.
The factors affecting durability of a metal to polymer bond are: the properties of the surface treatments (e.g. the production of a stable metal oxide layer), the adhesive film (e.g. the porosity of the adhesive) and the adherend material (e.g. the effect of moisture on the material properties).
As polymers, the mechanical behavior of adhesives is sensitive to the rate of straining that they experience [9].
In this study, it is showed that surface treatment affects adhesive strength and durability of aluminum/polycarbonate single-lap joints, and loading speed affects tensile-shear strength of adhesive joints.
The actual effect of abrasion may be a result of one or more of several factors, including enhancing Table 1.
