Abstract

Radiation shielding is one of the most crucial features of enclosure materials in spacecraft. The attenuation of electron radiation in hybrid materials, which consist mainly of carbon-fiber-reinforced plastics (CFRP), can be improved by laminating thin tungsten foils between the CFRP layers. In this paper, we study tensile behavior of thin foils to understand the plastic deformation of pure tungsten (W) foils and sintered tungsten heavy alloy (WHA) foils. The performed tests are simulated using the finite element (FE) method. Full 3-D FE models of tungsten and CFRP hybrids are generated to study the non-linearity response of different tungsten material models.
