摘要
Abstract
In order to prepare mesophase pitch-based nickel-plated carbon fibers, two kinds of nickel plating methods, electromagnetic stirring electroless and ultrasonic wave electroless, were compared. The results indicate that carbon fibers with high Ni-P content surfaces were successfully prepared by these two methods, and ultrasonic nickel plating method was suited for preparing continuous fibers. The research shows that after electroless nickel, the electromagnetic parameter of carbon fibers has decreased while the equivalent permeability increased, which is fit for the absorbing in low frequency. Epoxy resin composites were prepared by using electroless nickel carbon fibers as reinforcement, and the radar absorbing properties were studied also. The results show that the radar absorbing properties of the composites have been improved in both high frequency and low frequency when using parallel-arranged electroless nickel fibers respect to those without electroless nickel fibers. The maximum radar absorption of whole the composite with parallel-arranged electroless nickel fibers is -27.62dB at 14.88GHz and the total bandwidth lower than -5 dB is about 14GHz, bandwidth lower than -10dB is 6.5GHz, the radar absorbing property is remarkable.关键词
