Filament Winding of Microwave Absorbing Composites Cylinders

对吸波复合材料构件的缠绕工艺特性及存在的问题进行了分析,综合现代复合材料缠绕成型工艺,针对含有吸收剂的缠绕层,提出了"双辊同槽、双线夹芯复合"的浸胶工艺制备预浸纱带,以湿法缠绕工艺制备回转体吸波复合材料构件的工艺方法。工艺特性分析表明,选用相应的缠绕规律和工艺参数能够满足不同形态的回转体构件绕制,使吸收剂在各缠绕层中均匀分布、含量可控,保证了制件的吸波性能稳定、质量可靠。

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 roils for the same slot and double lines sandwich core, and absorbing composites cyl- inders are manufactured through wet filament winding. The results show the winding rules and the processing parame- ters 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.
