被动毫米波成像系统探测碳纤维复合材料研究

Detection Carbon Fiber Composites Using Passive Millimeter-Wave Radiometric Imaging System

为提高基质材料在被动毫米波成像系统(PMMW)的检出率,向基质材料内添加自制碳纤维化学镀材料.实验结果表明:镀银镍碳纤维(ANCF)、镀铜镍碳纤维(CNCF)、镀镍碳纤维(NCF)在PMMW中显示的相对电压值依次降低,成像效果依次增强;单纯基质材料矿酯和面粉几乎不能成像,石墨粉稍有成像,添加质量分数为0.3%的镀镍碳纤维(NCF)后,3种基质成像效果均明显提高.

To improve the effect of detecting base materials by using passive millimeter wave imaging system （PMMW）, the man-made chemical coated carbon fiber were added in detected materials and the composites were tested. Test results show that, for silver-nickel-coating carbon fiber （ANCF）, copper-nickel-coating carbon fiber （CNCF） and nickel coated carbon fiber （NCF）, the detected comparative voltage is decreased successively, but then the imaging distinguishing effect is improved accordingly. For base materials detected by PMMW, the esters or flour has little effect on imaging, while the graphite has slight one. After adding NCF with 0. 3% weight into the above three base materials, the images are improved greatly in PMMW.
