FABRICATION AND CHARACTERIZATION OF NANO-FE/WOODCERAMIC COMPOSITES

Wei Hong Zhou, Yun Shui Yu, Xue Liang Xiong

Abstract


Furan resin added with γ-Fe2O3 nanoparticles and Chinese fir sawdust were mixed and compressed into boards. The boards were then sintered in a vacuum furnace to obtain a nano-Fe/ woodceramic composite. The phase constitution, microstructure, and element distribution of the composite were examined by using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy disperse spectroscopy (EDS), respectively. The mechanical properties, volume electrical resistivity, and wave adsorption properties were investigated. XRD analysis indicates that α-Fe, Fe3C, and graphite carbon exist in the nano-Fe/woodceramic composite, and α-Fe promotes the graphite degree of woodceramic. SEM and EDS observations indicate that the composite has a porous structure and α-Fe nanoparticles distributed in the woodceramic. Experimental results show that the maximum values of bending strength and compressive strength are 11.74 MPa and 13.86 MPa, respectively. The minimum value of volume electrical resistivity is 0.021 Ω$cm. The minimum reflection loss value is11.45 dB at 9.68 GHz with 3mm thickness of absorbing layer.
