填充型吸波体阻燃外壳材料的研究

Investigation of Novel Flame-Retardant Shell Compound Materials Use for Filling Microwave Absorbing Materials

针对现有吸波材料外壳阻燃性能的不足,提出以玻璃纤维为主的新型复合外壳材料,并与聚丙烯空心板制备的方体的反射损耗进行对比。研究结果表明：在保证阻燃性的情况下,在低频下使用此类复合材料整体吸波性能较聚丙烯空心板材料提升了大约5-10 dB,在高频区有所下降,下降约10 dB,具有一定的应用价值。

In order to improve the flame-retardant of shell of the absorption materials. A novel compound shell material （ CSM ） which based on the fiber-glass was synthesized. In the same time, the rectangular shell were prepared by polypropylene cored slab （PCS）. The reflection loss （RL） of CSM and PCS were measured using a reflection method in a range from 2 to 18 GHz. The result indicated that containing CSM composite material exhibited good absorption property at low frequency compared to PCS. Whereas, the RL of the composite material was decreased at high frequency.
