This paper recycles and reuses sucker rod carbon fiber composite by microwave technique. The high temperature dielectric parameters of sucker rod carbon fiber composite were tested with the perturbation technique of cylindrical resonator. The structure and performance of the recovered carbon fiber samples were characterized by testing methods like scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffractometer (XRD). The results show that: the carbon fiber of sucker rod is good at absorbing microwaves. During microwave pyrolysis, the heating rate can reach 359.46 (℃/min), which greatly shortens the processing time. In addition, the microwave technique does not affect chemical bonds and functional group types, and the resulting recycled carbon fibers can be recycled well.
