摘 要:针对吸波材料存在的涂层大面积脱落和结构件承重不足导致材料吸波性能和力学性能急剧下降的问题,设计开发兼具优异吸波性能和力学性能的复合吸波材料。采用炭黑(CB)和羰基铁粉(CIP)作为复合吸波剂与环氧树脂(EP)复合制备复合吸波材料。利用单因素试验分析材料电磁性能,探究各组分质量比对材料吸波性能的影响,采用响应面试验分析了材料力学性能。建立高斯方程模型和多元回归方程模型,协同设计出CB/CIP环氧基复合材料各组分最佳质量分数比:CB、CIP、EP质量分数比为1%∶45%∶54%。模拟与实际具有一致性,为吸波材料的协同设计提供了可行性方案。A type of composite material with excellent microwave absorbing and mechanical properties was designed and manufactured due to the limited microwave absorbing and mechanical properties of materials,which was caused by large-area falling of coating from materials and insufficient load-bearing ability of structural units.Composite material was prepared by mixing epoxy resin(EP)with carbon black(CB)and carbonyl iron powder(CIP),which were used as microwave absorbents.The electromagnetic properties of the materials were analyzed by single factor experiment to investigate the effects of mass ratio on the microwave absorption properties of materials.The mechanical properties of materials were analyzed by response surface experiment.The optimum mass ratios of CB/CIP/EP composite obtained by coupling analysis through the Gaussian equation model and the multiple regression equation models were w(CB)∶w(CIP)∶w(EP)=1%∶45%∶54%.The simulation was in agreement with the experiments,which proved the feasibility of the simulation and provided a feasible scheme for the design of excellent microwave absorbing materials.
