A Study of Mechanical Properties of Polymer Composite Containing Tungsten Nano/Micro-Powder for Radiation Applications

Polymer composites are closely related and widely used in human life. Polymer composites have not only perfect physical and chemical properties for industrial goods but also relatively inexpensive price. In addition, manufacturing processes are relatively easy comparing with metallic ones. polymer composites are being utilized in a lot of fields such as plastic products, packaging things, and radiation shield. In particular, interesting of polymeric materials to prevent radiation is gradually increased for last few years. In addition, nano or micro-scale powder, such as tungsten (W) and lead (Pb), can be dispersed in polymer composites to enhance ability of radiation shield. Therefore, the researches for polymer composites containing nano or micro-scale high density elements are gradually tried recent years. In addition, the environmental issues gradually demand the less use Pb for radiation shield area. However, experimental results of mechanical properties, such as tensile strength and elongation, for these composites are still lack and much required to apply for industrial approaches. It is also important to know mechanical properties of these composites to maintain stability after forming or manufacturing, especially, for radiation shield purpose. In the paper, we introduce the experimental results of mechanical properties about such polymer composites which are completed with mixing nano and micro-size tungsten powder
