Microwave absorbing applications: Characterization of the Electromagnetic and Mechanical Properties of Iron Reinforced Natural Fiber Composites

Abstract

It is still difficult to create an effective microwave absorption composite made of natural Fibers that also has strong tensile and electromagnetic properties. In this study, experiments are carried out to create new hybrid microwave absorbent composites made of jute Fibers bonded with iron. This experimental study's goal is to improve absorption and widen the absorption bandwidth while maintaining acceptable tensile properties. Hence four samples have been used been created and tested with varying iron levels and a constant jute Fiber content. The waveguide-based microwave measuring approach has been used to measure the electromagnetic parameters. It is discovered that an ideal sample has good X-band microwave absorption characteristics. Additionally, the created composite is put to the tensile test, where it is discovered to have an average Young's modulus. Current investigation to observe the values of 9.4 GPa for the modulus, 0.08 for the ultimate strain, and an average ultimate 49 MPa is the tensile strength value. Analyses using a scanning electron microscope were used for the interior failure behavior of the tensile-tested specimen and establish the primary mechanisms of failure like matrix cracking, Fiber breaking, and delamination failure. The outcomes show the potential of the manufactured composite for diverse tactical uses. determined (transmission and reflection coefficients). At room temperature, all measurements were taken.
