摘要
为了研究燃烧速度对镁/聚四氟乙烯红外诱饵剂辐射强度的影响,首先对不同配比镁/聚四氟乙烯红外诱饵剂的燃烧速度、辐射强度和质量辐射能量进行了测定和计算,确定了在镁与聚四氟乙烯的配比为50∶50时,燃烧时的红外辐射强度最大;然后在镁与聚四氟乙烯混合物中加入不同含量的碳纤维,实验发现随着碳纤维含量的增加,燃烧速度和红外辐射强度迅速增加;通过分析确定了导温系数随着碳纤维含量增加而提高,进而使燃烧速度加快,使得红外辐射强度的增加。
The influence of burning rate on the infrared radiation intensity of Mg/PTFE infrared composition was studied. The burning rate, infrared radiation intensity and quality radiation energy for Mg/PTFE infrared composition of different ratios were measured and calculated, it was obtained that the infrared radiation intensity is the largest when the ratio of Mg and PTFE is 50：50. The different content of carbon fiber was added to Mg/PTFE composition, and the burning rate and infrared radiation intensity increase along with the content of carbon fiber increases. It was defined that the more the content of carbon fiber, the larger the thermal diffusion coefficient of composition, and than the burning rate is speeded up, the infrared radiation intensity increases by analysis.
