EFFECT OF OIL PALM SHELL CARBON-POLYESTER RESIN COMPOSITE ON MICROWAVE ABSORBER PROPERTIES
Keywords:
Composite, Microwave Absorber, Dielectric Properties, Waste UtilizationAbstract
Pyrolysis effect on the dielectric properties of microwave absorber composed of palm shell
carbon-polyester resin composite was studied. The permittivity, E, and loss tangent, tan is
of the composite were studied in the 8 to 12 GHz frequency range which emphasize the
influence of carbon 'concentration (mass %) of pyrolysed oil palm shell carbon at 600°C,
700°C and 800°C. It was'observed that the increase of carbon concentration inside each
measured composite influenced the increase of E: and tan is condition. This indicates the
possibility of using carbon derived from oil palm shell residue in providing significant loss
in contributing to microwave absorption, as well as an alternative in managing the
increase of oil palm shell residues throughout the country.
