Preparation and Microwave Absorption properties of Glass beads/Carbon Fiber with Electro less Ni-Plating

The electroless Ni-Plated technique was used to fabricate the coupled and activated Glass beads /Carbon Fiber. The microstructure of Ni-P-GBs/CFs was analyzed by IR, SEM, EDS, and the microwave absorption properties were characterized by Vector Network Analyzer. The results showed that Ni-p alloy layer is dense and continuous after electro less plating. When the mass ratio is 3:2(GB/CFs), and mass percent of mixed dusty materials is 22.5%, the average loss value is lower than -5 dB in the frequency range of 2 similar to 18 GHz, while the greatest loss value is up to -12.4dB in the 15.1 GHz.
