摘　　要：微螺旋炭纤维独特的螺旋手性结构赋予其优异的吸波性能,本文结合自身实验,综述了微螺旋炭纤维复合吸波材料的研究进展,并分析其吸波机理在螺旋手性结构引起的电磁波交叉极化,同时对发展更好的微螺旋炭纤维手性复合吸波材料提出了可行建议。Carbon micrecoils（CMCs） showed excellent absorption properties for electromagnetic（EM）waves over a wide frequency range because of their unique helix-chiral morphology. Combined with the experiment, researches on the EM wave absorption properties of CMCs chiral composite are reviewed. The absorption mechanism preduced by EM cross - polarization coupling depending strongly on the particular spiral chiral morphology are analyzed. Some feasible advices to obtain desirable EM wave absorber of CMCschiral composite materials are also proposed.
