Abstract
The knowledge of how to process composite materials and combine them with radiation absorbing centers, using different components, additives and polymer matrices with suitable electromagnetic properties (dielectric constant and tangent loss), allows the production of multifunctional composites that can function as conductors or microwave absorbing materials. Thus, the purpose of this study was to process and evaluate the electromagnetic properties of multilayered multifunctional composites made with layers of glass fiber cloths or nonwoven glass fiber veils pre-impregnated with formulations based on carbon black. Electromagnetic properties of the multifunctional composites were evaluated by measuring the reflection of microwave radiation using the waveguide technique in the X-band (8.2 to 12.4 GHz). The results show that the multifunctional composites absorbed 90% to 99% of the energy of the incident microwave radiation. The high attenuation of the incident microwave radiation combined with their small thickness indicate that these multifunctional composites could be used in a number of military and civilian applications.
