Composite wicks are made of two or more materials or its layer configurations.
The familiar wick materials are copper, stainless steel etc which poses the capillary driving force.
The type of nano materials used to enhance the thermal conductivity is the ability of material to transfer heat which depends on its volume added with base fluid.
The temperature reduction at the evaporator was essential and is obtained with various temperature rise depends on the Nano materials used.

Damping Responses of Viscoelastic Composite Material Structure Muhammad Iqbal Sabir 1, a , Guo Wan-Tao2, b , Liu Er-Bao 1, c, Li Li1, d,* 1 College of Materials Science & Chemical Engineering, Harbin Engineering University, China 2 LuoYang Ship Material Research Institute, LuoYang, China a iqbalsabir@hotmail.com, b guowantao@sohu.com, c liutong_05@163.com, d,* lili_heu@hrbeu.edu.cn Keywords: Composite materials, Viscoelastic, nonlinear Damping, Vibration Abstract: The work reported in this paper describes the behavior and prediction of damping properties of the 3D composite laminated engine mount shell structure.
Viscoelastic materials have been widely used for that purpose.
The continuous desire for materials having excellent properties, which would be light, stiff and have better damping characteristics have lead to consider composite materials not only from the point of view of how stiff or strong they are, but also from the point of view of how good a damping they can provide.
Experimental and analytical characterization of damping is not easy, even with conventional structural materials; and the orthotropic type of composite materials get even more complex.
This study presents that composite materials have the potential to use as engine or damping mounting devices.
