在聚酰胺(PA)或聚丙烯(PP)两种树脂中，用不锈钢纤维(SSF)作导电填料，采用注塑工艺制备新型雷体材料，并进行物理、力学和吸波性能测试。经试验得出，当SSF质量分数为15%时,两种材料的加工性能良好，满足雷体物理、力学性能要求；采用弓形框法测量材料的微波吸收率，PP／SSF和PA／SSF复合材料在8.2～12.4 GHz频率范围内的反射衰减均大于10 dB，将羰基铁与丙烯酸树脂按不同比例混合制备0.4 mm厚度微波吸收涂层分别涂覆两种材料，发现反射衰减值分别提高6.2～11.3 dB和17.9～40.7 dB。

Two new mine materials were prepared by using stainless steel fibers(SSF) to fill polyamide(PA) or polypropylene (PP) with injection molding process,the physical,mechanical and absorbing properties of the two materials were tested. The results show that the processing properties of the two materials are good,and meet the requirements of the physical properties of mine bodies when the mass fraction of SSF is 15%. The microwave absorption rate were measured by using military standard with arched test method,reflection attenuation of the two materials is more than 10 dB in the 8.2~12.4 GHz frequency range. Carbonyl iron with an acrylic resin were mixed in different proportions to prepare microwave absorbing coatings with thickness of 0.4 mm, then the coating was used to coat the PP/SSF and PA/SSF materials respectively, which resulting that reflection attenuation values increase by 6.2~11.3 dB and 17.9~40.7 dB.
