为了提高中空多孔碳纤维（HPCF）复合材料的吸波性能，本文研究了一系列嵌入频率选择表面（FSS）的HPCF复合材料。制作了不同单元尺寸和位置的粘贴型FSS样品，并进行了粘贴型FSS的实验研究。结果表明，单元尺寸和FSS在复合材料中的位置对样品的反射性能都有重要影响。没有FSS的HPCF复合材料的−10dB带宽为0GHz，而粘贴FSS的HPCF复合材料的−10dB带宽高达10GHz。结果表明，频率选择表面能有效地调节和改善HPCF复合材料的吸波性能。
In order to improve the microwave absorbing properties of hollow-porous carbon fiber (HPCF) composites, a series of HPCF composites embedded with frequency selective surface (FSS) were investigated in this paper. Samples pasted FSS with different element size and locations were fabricated, and experiments were carried out to find the effects of pasted FSS. It is found that both the element size and locations of FSS in the composites are critical for the reflection property of the samples. The −10dB bandwidth of HPCF composites without FSS is 0GHz, while that of HPCF composites pasted FSS is up to 10GHz. The results show that FSS can effectively adjust and improve the microwave absorbing properties of HPCF composites.
