Automated Registration System of the Density Change at the Depth of Composite Materials, in High Temperature Conditions

The continuously wider use of composite materials (CM) in various sectors of human activities imposes the growth of new methods and the construction of new appliances in order to study their physical and chemical attributes, such as density and effective atomic number, especially in a dynamic way (in situ) in high temperatures. In this paper, an automated system for the registration of density change at CM's depth is described. This system makes extensive use of radio isotopic methods that are proved to be successful techniques of non destructive method (NDC).
