A radio absorbing composite material based on compounded rubber and modified nonwoven fabric

Resumo

The paper discusses the relationship between the reflection of microwave electromagnetic radiation and the composition of a composite multilayer material made from rubber filled with carbonyl iron particles and nonwoven fabric reinforced with carbon fiber. It is found that the radio absorbing composite material has low reflectivity at electromagnetic wave frequencies less than 4 GHz. It is shown that the composite material has the highest absorption capacity when electromagnetic waves are incident on the nonwoven fabric layer of the material.
