Based on modern filament winding technology, processing property and puzzles are analyzed for the microwave absorbing composites cylinders. For winding layer including absorbers, a technique is adopted, which prepreg is prepared using double rolls for the same slot and double lines sandwich core, and absorbing composites cylinders are manufactured through wet filament winding. The results show the winding rules and the processing parameters can meet cylinders manufacture. The content of absorbers dispersed in the different prepreg well-proportioned can be controlled,and the microwave absorbing performance is excellent.
