Characterization of Kevlar Fiber-Reinforced Absorbing Composites

Abstract:

In this paper, addition of Fe-Ni, MnZn-ferrite, and CNF (carbon nanofiber) absorbers in the Kevlar fiber fabric-reinforced epoxy resin composites resulted in excellent absorbing properties as well as other required properties such as light-weight (as low as 2.2 g/cm³), small thickness (~2 mm), high mechanical strength (up to 380 MPa) and thermal stability (up to 120 °C). Reflection loss testing of the laminates FM-3 showed that the peak reflection loss was-45 dB at the frequency of 10.4 GHz, and the absorbing waveband at-10dB was 12 GHz (from 6 to 18GHz). The study also indicated that the content of the added absorbers was limited by the viscosity (or flowability) of the resin-absorber mixed suspensions.
